Safer hydrogen projects.

Hydrogen will be at the heart of the world’s energy transition away from natural gas. However, while there are many ways to produce and use hydrogen, there is a common denominator: all require monitoring for safety. Today, Teledyne Gas and Flame Detection has a complete product offer for hydrogen that not only encompasses end-to-end gas, flame and fire detectors, but also a complementary range of leading-edge controllers, services and cloud data management options. As a result, more and more companies engaged in hydrogen transitioning projects are placing their trust in Teledyne Gas and Flame Detection as a one-stop-shop for all their safety needs.

Teledyne Gas and Flame Detection’s innovative fixed and portable systems have been ensuring the safe use of hydrogen for decades, with the company today providing a critical contribution to a safe and efficient energy transition. Products, systems and services are available to support the full hydrogen spectrum – production, distribution and storage – across a host of established and new applications. In addition, a wide range of sensors is available for the main gases in the hydrogen value chain, including methane, ammonia, carbon monoxide and carbon dioxide. Many are suitable for integration into SIL2 or SIL3 systems.

Fixed gas detectors.
A case in point is the highly successful DG7-SIL2 intelligent fixed gas detector with integral display, which is ideal for detecting hydrogen and other gases related to hydrogen and hydrogen derivatives. This microprocessor-driven instrument is fully configurable using a wireless hand-held terminal or a hard-wired HART option, providing true flexibility to the installer and reduced service costs. The unit can interface directly with a wide range of panels, controllers and PLCs.

Another attractive option in fixed gas detectors is the OLCT 100-SIL2, which offers a range of housings and sensors for the full hydrogen value chain. It comes with a 4-20mA output and carries SIL certification in accordance with EN 50402.

Part of the same product family, the compact OLCT 20 fixed gas detector is ideal for installation in shelters or on skids, where there is a need for monitoring in very small spaces or for on-board applications. These transmitters again provide a 4-20mA output with the potential for direct connection to PLCs.

Flame detectors.
Many customers ask if they can use their existing natural gas flame detector with hydrogen. However, many flame detection systems for use in hydrocarbon processing just ‘see’ combustion products such as water, soot or carbon dioxide. When pure hydrogen burns it forms only water, making it necessary to use special flame detection equipment.

Teledyne GFD has an exciting new offer in this area: the Spyglass IR3-H2-V flame detector quickly detects hydrogen and other ‘energy transition’ fires in support of rapid response efforts. A near-infrared camera provides personnel with the ability to see invisible hydrogen flames in all weather and light conditions. Notably, the detector automatically records video, providing additional means to study the cause and development of fires.

For building networks of wired or wireless gas and flame detection equipment to enable integrated site safety strategies, it will be necessary to employ a controller. Here, the Teledyne GFD modular and flexible MX62-SIL2 features a large, fully interactive 10" (up to 15") high-definition colour touchscreen, 64 secure channels and a back-up processor to ensure continual measurement.

Portable gas leak detectors.
Portable gas detection equipment is perfect for use by personnel working in locations where compressed hydrogen is present and may potentially leak. Hydrogen has a wide flammability range in air: from 4% to 74% at atmospheric pressure. To ensure safety at all times, Teledyne Gas and Flame Detection portable gas detection systems have an alarm at 50% of the LEL, or 2% hydrogen.

Among the latest developments is the versatile GS700-Hydrogen, an upgraded version of the company’s popular and successful Gasurveyor 700 (GS700) that adds the ability to detect hydrogen. The new ATEX-certified GS700-Hydrogen therefore offers both natural gas and hydrogen detection in a single instrument. Ideal for leak detection around major equipment, large sites, and pipeline installation and maintenance, the GS700 has an optional GPS mapping system. It is possible to store and process data from the field in Teledyne GDCloud software to map the location of measured data and pinpoint the geo-location of any leaks. The device, which offers exceptional flexibility and performance in all gas utility applications, has already seen adoption at several hydrogen network test sites.

Personal safety gas monitors.
Teledyne Gas and Flame Detection can offer a comprehensive range of wearable devices for monitoring hydrogen, ammonia and all major gases relating to the hydrogen value chain. For example, the PS200 four-gas compliance monitor is compact, lightweight, water resistant and extremely robust, while the larger PS500 model provides the potential to detect up to five gases.

Ultimately there will be many roads to the hydrogen economy based on decarbonisation and new applications. And while some harbour concerns about hydrogen’s tiny molecules that can leak through the smallest of cracks, Teledyne GFD has the expertise and solutions to render hydrogen a very ordinary gas. The company has been working with customers for decades to ensure the safety of personnel and assets when handling hydrogen. Today, a complete portfolio of hydrogen gas and flame detection systems from Teledyne Gas and Flame Detection is ready to empower a safe and efficient transition to the hydrogen economy.

Infrared gas detector.

The only device on the market that provides IR detection to first-class SIL 2 high demand mode and SIL 3-capable IEC 61508 ed. 2 with a proof test interval of 8760 hours.

Teledyne Gas & Flame Detection has provided its GD10P infrared gas detector with a full firmware revision and upgrade, enhancing the product’s performance in high demand mode SIL2 approved applications. This milestone, as part of the product’s continuous improvement lifecycle, builds on circa 30 years of proven field experience for GD10P in the harshest industry environments and further supports the provision of a far longer warranty than conventional infrared gas detection systems.

Functional safety
New firmware within GD10P complies with the highest functional safety standards. The safety function has been assessed in conformity with the IEC 61508 ed. 2 standard according to Route 1S: Requirements for the avoidance (prevention) and requirements for the control of systematic faults, as well as Route 1H, which is based on hardware fault tolerance and safe failure fraction concepts.

High demand mode is where the frequency of demands for operation made on a safety-related system is greater than one per year.

While most safety-based applications in the process sector require only ‘low demand mode’ solutions, ‘high demand mode’ safety-critical applications are becoming increasingly common. As a result, gas detectors such as the GD10P must demonstrate their suitability and competence in line with the latest SIL2 third-party certification.

Solid-state infrared source
In comparison with other infrared (IR) gas detectors, the new firmware adds further to GD10P’s differentiating factors, which include a solid-state infrared source. Here, the optical chamber, featuring two independent IR silicone (semiconductor) sources, is sufficiently robust and stable to merit a 15-year warranty. This compares favourably with the standard 2-3-year warranty commonly available with conventional IR detectors. The GD10P also features heated optics to prevent condensation, a HART interface, fail-safe operation, extended diagnostics and low maintenance requirements thanks to features such as a scratch-proof sapphire lens/mirror (instead of traditional glass).

Whereas 2-3 measurements per second is the norm with many IR gas detectors, the GD10P can perform 50 measurements per second. More sampling means less false alarms, higher accuracy, faster response time and, in turn, lower operational costs. Further cost reductions arrive as the fit-and-forget GD10P requires no calibration. In contrast, conventional IR gas detectors require calibration twice a year.

Thanks to its solid-state dual sources, the GD10P, which has origins in the oil and gas industry, is ideal for use in extremely hot, cold or wet environments. Conversely, traditional alternatives suffer negative effects from factors such as vibration, flow rate and environmental influences like heat and dust, which means their plastic filter/sinter can melt or clog. Other noteworthy advantages of the GD10P in comparison with conventional gas detectors include a calculated life of 60 years (versus five years) and a T90 response = 1 second for methane (versus >8 or 9 seconds). 

Proven in the field.
Among countless real-life applications, one worth calling out is the detection of ethylene in recirculating air on board large industrial machines. Most applications of this type now require SIL2 level gas detection in high demand mode, and GD10P offers this feature without hardware redundancies. This particular application requires high accuracy that would otherwise necessitate specific process monitoring measures beyond safety devices alone. However, the GD10P matches the requested accuracy, allowing the customer to make savings in equipment investment costs as each machine required multiple detection points.

Another common example of the GD10P’s aptitude is evident in the detection of propane at industrial welding stations. After a previously unsatisfactory experience using catalytic detectors, the GD10P is proving ideal in these dusty conditions thanks to ‘auto-zero’ self-adjustment of the detector. Furthermore, the large optical chamber provides the opportunity to send two different warning levels that indicate the requirement for cleaning and avoid the need for ‘real time’ servicing.

Further exemplifying the benefits of GD10P is its application involving the detection of ethanol when monitoring the storage of perfume essence. The aim was to avoid the loss of expensive perfume essence diluted in ethanol, perhaps due to a tank leak, and avoid the increase of ethanol concentration in a confined area. The GD10P, due to its target gas selectivity (narrow band optical filter) and very low response time, was the optimum solution. The detectors have been in service for four years.

Low cost of ownership
These and many other case examples build upon a large global installed base of more than 100,000 GD10P IR gas detectors, many of which are operating in harsh conditions. Lower cost of ownership is a further advantage as only one detector is required per system, instead of several with low demand mode SIL2 approval.

Notably, the firmware upgrade aligns Teledyne’s GD10P with the requirements of the latest third-party certification advancements, increasing confidence in the platform’s traditional feature sets. When coupled with a depth of innovation based on real world data from in-field proven use over several decades, the GD10P knows few limitations, irrespective of the application’s size, environment or location.

Gas detection in water treatment.

When choosing a gas detector for use in water treatment applications, engineers should focus on simple, efficient, proven products from a supplier experienced in the provision of end-to-end solutions for this challenging marketplace. Teledyne Gas & Flame Detection can offer a wide repertoire of detectors based on a number of effective sensor technologies

As a process, the treatment of wastewater has a number of inherent hazards, namely the generation of flammable and toxic gases such as methane (CH₄) and hydrogen sulphide (H₂S). Furthermore, oxygen (O₂) enrichment and ozone (O₃) can present safety risks if the process requires technologies that use these gases, while for pH control some water treatment plants rely on carbon dioxide (CO₂), which can be toxic and create an oxygen deficiency hazard.

Toxic chemical gases such as ammonia (NH₃) and chlorine (Cl) are common in the preparation of drinking water, which means leak detection is essential to identify any emissions from storage or processing equipment.

Essential protection

Water treatment plants can protect staff and contractors from the dangers of explosion, intoxication and fire by ensuring portable gas detectors form part of their personal protective equipment (PPE). Indeed, for temporary or mobile use in confined spaces, Teledyne offers a wide range of portable gas detectors designed to meet the requirements of the water/wastewater sector.

Of course, many more advantages accrue from combining portable detectors with their fixed counterparts. Fixed gas detectors help deliver the appropriate process automation levels required to reduce running costs and manage risk with minimal operator intervention.

As well as averting health risks, careful product selection can also minimise the gas detector’s total cost of ownership (TCO). H₂S, for instance, can corrode metals like steel, copper and brass, which means a gas detection sensor housed in stainless steel is a wise choice.

Technology decisions
Another critical selection decision involves the type of sensor technology, which for gas detection typically centres on electrochemical, semiconductor, infrared (IR) or catalytic.

For water treatment plants that want to monitor O₂ deficiency or enrichment, or the presence of low levels of toxic gases such as H₂S or Cl, electrochemical sensors are the common choice. A popular pick here is the Teledyne DGi-TT7-E intelligent gas detector. This easy-to-use product features an integral daylight-readable alphanumeric display that indicates local status and alarm level.

The selection of semiconductor sensors, which have a longer operating life under harsh operating conditions than their electrochemical counterparts, usually occurs where very high concentrations of H₂S are present, or where ambient temperature or humidity is high. With its high reactivity, strong signal stability and long operating life, the Teledyne CTX 300 fixed detector for O₂, CO₂ and other toxic gases, is a popular solution. The CTX 300 transmits data in record time, while maintaining the unit is easy thanks to its pre-calibrated sensors and optional LCD display.

IR sensors are preferable for the detection of explosive gases such as CH₄ or CO₂, or for very corrosive atmospheres containing high levels of H₂S. Here, detection is based on the fact that each gas absorbs light on a specific wavelength in the infrared spectrum. Notably, the robust nature of IR sensor cells from Teledyne Gas & Flame Detection means they require only one annual maintenance routine and come with a five-year guarantee. A case in point is the Teledyne GD10 series IR gas detector, which differs from all other models because it utilises silicon-based solid-state IR sources that carry a 15-year warranty. Teledyne Gas & Flame Detection offers the longest combined detector and IR source guarantee on the market.

The most common alternative to an IR sensor is a catalytic sensor, which is not as durable but consumes less power. As many water treatment plants are in remote locations and take advantage of solar energy, this factor can prove attractive. Among the Teledyne recommendations here is the DG-TX7 intelligent gas detector, which houses a pair of OXYCOL catalytic sensors.

Teledyne Gas & Flame Detection can also provide sampling kits for the water treatment industry, for applications such as areas highly saturated in H₂S.

As with all gas detection tasks in the water treatment sector, it is essential to ensure the technology is adapted to the application. Strong concentrations of gas, either immediate or accumulating over time, along with harsh and/or corrosive operating environments, demand proven products. But each application is different, so consulting with a specialist is vital in defining the optimum solution for any particular requirements.

Portable Gas Detectors and staff protection during COVID-19.

There are many ways that portable gas detectors for personal use can deliver individual protection for key staff during the COVID-19 pandemic. Kevin O´Donnell, EMEA Business Development Manager at Teledyne Gas and Flame Detection, uses his expertise to answer a number of pertinent questions.

Q. What are the links between COVID-19 and gas detection?

A. The packaging, transportation and storage of COVID-19 vaccines at low temperatures necessitates the use of dry ice, which is a form of carbon dioxide (CO2). If CO2 escapes in its gaseous form, there is a danger to factory, logistics and healthcare workers, most of whom will be unfamiliar with dry ice and its potentially harmful effects. Although there is a clear global need for vaccine urgency, employers also have a responsibility to avoid compromising worker health and safety.

Another application concerns the storage and use of oxygen at temporary hospitals, a number of which are now in operation across Europe to provide COVID-19 patients with emergency ventilation. These facilities do not have permanently engineered solutions to monitor for oxygen leaks, which presents the need for additional safety precautions.

In both applications, portable gas detectors worn by personnel can monitor for gas leaks and alarm against dangerous exposure.

Q. What are risks of exposure to excessive levels of CO2 and oxygen?

A. Dry ice is solid-state CO2. However, sublimation of CO2 occurs at temperatures above -78°C, when it becomes gaseous. CO2 in this form is heavier than air and tends to take the place of oxygen, presenting a risk of anoxia. As little as 3% CO2 by volume can lead to an increase in heart rate and blood pressure, while 5% will likely prompt dizziness, confusion, headaches and shortness of breath. All of these conditions can prove dangerous in a workplace situation. Moreover, staff absenteeism due to feeling poorly is a major risk to the effectiveness of vaccine supply chains.

As for oxygen, excessive amounts of this gas in the atmosphere due to leakage from tanks or equipment presents a higher flammability risk.

Q. What are the exposure level guidelines for workplaces?

A. Alarm levels for CO2 in the PS500 personal gas monitor from Teledyne Gas and Flame Detection, for example, are set well below 3-5%. In fact, 0.5% CO2 by volume is the EH40 prescribed time-weighted average safe exposure limit for workplaces across an 8-hour working day. There is also a guideline for STEL (short-term exposure limit), which is 1.5% CO2 by volume over a 15-minute period.

With oxygen, leaks into the workplace atmosphere above 25% by volume, change the flammability of the environment. Again, a personal gas monitor, in this case the high-performance yet cost-effective Protégé ZM features appropriately set levels of 23% Vol to warn against any impending danger.

Q. How are personal gas monitors used?

A. The device simply clips to a lapel or belt loop, for example, from where it can sense danger from every direction and make that vital connection between excessive gas exposure and personal safety. A detector such as the Protégé ZM measures just 94 x 56mm and weighs only 76g.

Personal gas monitors are extremely easy to use and typically feature a single button switch-on. If an alarm triggers, the monitor will beep, shake and flash [audible, tactile and visual] to ensure the user acknowledges the warning in all kinds of environments, including noisy ones.

Q. Is there access to recorded data?

A. Data-logging capability sees a memory store taken every minute. Users can upload the data to a PC, where they will see a time and date stamp against exposure events. This evidence is useful if there is a requirement for an investigation or report.

Q. What is the best way to clean/sanitise gas detectors during COVID-19?

A. With frequent shift changes at factories, logistics hubs, vaccination centres and temporary hospitals, there is a likelihood that staff will share personal gas detectors. To avoid any potential for virus transmission, it is good practice to clean the monitors between shifts. The best way to ensure surface cleanliness is to use mild soap and water applied to a damp cloth.

Do not use alcohol wipes or other alcohol-based cleaning products, as the sensor will detect the alcohol and provide a false reading. Users should also avoid silicone, chlorine or bleach-based cleaning products.

Q. What about service and calibration?

A. It is highly advisable that users follow service and calibration guidance for their monitors to ensure quality and reliability. Working with a gas detector that is out of calibration or needs a sensor replacement, for example, defeats the objective and places staff at risk. Optimum intervals are dependent upon the working environment, but annual service and calibration is typical. A two-year warranty is applicable assuming adherence to the service schedule.

Q. Why is Teledyne Gas and Flame Detection qualified to help in the COVID-19 emergency?

A. Due to the knowledge, expertise and experience of Teledyne Gas and Flame Detection across many sectors that deal with potentially dangerous gases in confined spaces, the company has proven, high-integrity solutions that can help keep workers safe during the pandemic. Safety is at the heart of all Teledyne gas monitoring and detection solutions.

Maintain workspace exposure standards!

The long-term effects on health resulting from exposure to chemical agents are well documented. Employers contravening the new exposure limits could not only be risking the health and safety of their team, but find themselves subject to prosecution.

3M™ Gas & Flame Detection is advising businesses or public services that do not comply with updated workplace / occupational exposure limits to chemical agents, could potentially face stern consequences, including prosecution. August 2018 saw the deadline pass for compliance with the revised EU Directive 2017/164/EU. However, for businesses that remain concerned, 3M™ Gas & Flame Detection is offering guidance to ensure the regulations are met.

Indicative occupational exposure limit values (IOELV) are health-based, non-binding values which are derived from recent scientific data and take into account the availability of reliable measurement techniques. For any chemical agent with an IOELV set at EU level, Member States are required to establish a national occupational exposure limit. In the UK, for example, EH40 Workplace exposure limits from the Health and Safety Executive (HSE) have been updated directly in line with EU Directive 2017/164/EU. In the latest revision of EH40, which was introduced in August 2018, new limits have been introduced for 31 substances.

“The updated regulations set out the latest IOELV limits. These have been established in relation to a reference period of 8 hours and are referred to as long-term exposure limit values,” explains Neil Gwinnutt, UK & Ireland Sales Manager, 3M™ Personal Safety Division - Portable Gas Detection. “In addition, for certain chemical agents, shorter reference periods exist, typically 15 minutes, and these are referred to as short-term exposure limit values. In line with the ongoing desire to create safer workplaces, IOELV limits have consequently been reduced in the updated regulations. This means any business that believes it was working safely to previous limits, may now be exceeding them.”

By way of example, consider carbon monoxide (CO), which is an extremely common by-product of many industrial processes such as wastewater treatment, steelmaking, forging, chemical production, and oil and gas extraction. The 8-hour exposure limit for CO has been reduced from 30ppm to 20ppm while the 15-minute exposure limit has been tightened from 200ppm to 100ppm.

“The changes in CO limits will have an impact on many working practices including fire brigades and heating engineers” says Mr Gwinnutt.

Another common gas, hydrogen cyanide (HCN), which is found widely in the plastics manufacturing industry, has seen a new 8-hour exposure limit introduced at 0.9ppm while its 15-minute exposure limit has been reduced from 10ppm to 4.5ppm.

“New limits have also been introduced for nitrogen dioxide (NO2) and nitric oxide (NO), which are commonplace in the rail industry and generated by diesel locomotives. As a result, rail companies need to ensure that engineers working in maintenance depots or in tunnels are not exposed to levels beyond those stated.”

Flame detectors.

The Rosemount 975 flame detectors, announced recently by Emerson,  is a complete line of optical flame detectors designed to perform in the harshest environmental conditions and connect directly to alarm or automatic fire extinguishing systems.

“When you’re concerned with protecting lives and the future of your operations, you need an optimum solution for each facility and location,” said Lara Kauchak, vice president and general manager for flame and gas detection, Emerson. “We believe this comprehensive new line of flame detectors provides the reliability and functionality to meet all of our customers’ flame detection coverage needs.”

The new line incorporates a variety of flame detection technologies that will provide optimal coverage for a wide range of process industries, including upstream oil and gas installations, chemical plants, and refineries. Multi-spectrum infrared sensor technology detects hydrocarbon fuel and gas fires as well as ‘invisible’ hydrogen fires with wide area coverage and strong false alarm immunity. Integrated ultraviolet and infrared sensor technology rapidly detects hydrocarbon-based fuel and gas fires, hydroxyl and hydrogen fires, as well as metal and inorganic fires with robust false alarm immunity.

Built to be extremely durable and weather-resistant, the Rosemount 975 flame detectors feature heated windows for operation in harsh weather conditions, such as snow, ice, or condensation; broad operating temperature ranges from -67 F to 185 F (-55 C to 85 C); and multiple output options for maximum flexibility and compatibility. The Rosemount 975 line is approved to Safety Integrity Level (SIL) 2 (TÜV). The detectors can even be tested in-field with a specially designed flame simulator at distances of up to 40 feet (12 metres) from the detector, eliminating the need for personnel to stand on scaffolding or supports to access the detector.

Flare process control.

CyboSoft has developed a flare process control solution that can effectively control the flare vent gas heating value to meet EPA regulations. An MFA flare control system has been running in a plant for 1.5 years and achieved substantial economic benefits for the customer.

EPA is ramping up its enforcement actions to investigate illegal air emissions by industrial flares. Since EPA will want to see the flare net heating value data from the previous 5 years when they issue a Clean Air Act (CAA) section 114 letter, it is very important for all flare operators to install a real-time heating value sensor and control system to comply with the limits and save records.

CyboSoft CEO Dr. George Cheng said, "We have the technology, products, and experience in flare control and want to help the industry effectively control this complex and difficult process."

Most refinery and chemical plants operate flares to burn off waste gas for operational and safety reasons. The vent gas heating value of a flare must be monitored and controlled based on EPA 40CFR60.18 rules. For steam-assisted or air-assisted flares, the net heating value of the gas being combusted must be 300 Btu/scf or greater. When the waste gas heating value is below this limit, supplemental gas such as natural gas must be added to assure sufficient combustion and minimal emission. The MFA control system diagram illustrates a flare process and its key variables.

There are online calorimeters on the market that can determine the heating value or Wobbe-index of a gas in real-time. However, adding a heating value (HV) control loop can be a challenging task due to the following reasons: (1) There are large and varying time delays in the HV control loop; (2) The HV process is nonlinear in different operating conditions; (3) Multiple waste gas streams in a plant are sent to the flare stack, where stream flows can vary widely causing big disturbances to the heating value; (4) The HV of each waste gas stream may change widely under operating condition changes; and (5) Nitrogen is often used as purge gas to keep positive pressure in the vent pipe, making the process more complex.

"The flare process is difficult to control using conventional PID controllers. On the other hand, model-based control can be costly to develop and maintain. CyboSoft's Model-Free Adaptive (MFA) control methods and products are well suited for this application and we are confident to say that it is the most cost-effective and robust control solution for flare processes," Dr. Cheng added.
