Safe sulphur recovery.

A dedicated sulfur recovery unit webpage has been launched by Applied Analytics™ [AAI], to provide clients with a clear picture of the solutions we can provide. The webpage includes a process flow diagram of the sulfur recovery unit and calls out the measurement points of interest with descriptions and pictures of our equipment.

Hydrogen sulfide (H₂S) is a byproduct of processing natural gas and high-sulphur crude oil. At low concentrations, H₂S has an odor much like rotten eggs, is corrosive and fatal at concentrations greater than 500 ppmvl. This extremely dangerous byproduct must be closely monitored and the amount of H₂S released to the atmosphere must be minimised.

A Sulfur Recovery Plant serves to convert H₂S in an incoming gas stream into elemental sulphur where it can be stored or repurposed. Sulphur recovery plants are required to recover 95 to 99.99% of the total sulfur that is introduced into the plant. Emissions regulations are becoming more stringent with each year that passes, which is why high-quality industrial analysis equipment in Sulphur Recovery Plants is of major importance. Applied Analytics Inc. manufactures analytical solutions used to control and optimize the operation of the sulfur recovery unit including measurements in the sour/acid gas inlet, Claus tail gas, tail gas treatment unit (TGTU) and sulphur pit.

H2S Sensor.

Crowcon has developed a high-temperature hydrogen sulphide (H2S) sensor to work alongside its XgardIQ fixed point detector and transmitter to support the oil and gas industry in the Middle East.

Ala Ayoub, Regional General Manager at Crowcon, explains, “The Middle East oil and gas industry contends with high levels of H2S in their gas production operation. More recently, oil production is experiencing increased risks from H2S gas, as they extract more, heavier oils. Employees working in these extreme conditions need reliable, effective equipment to help minimise risk.”

Detection of H2S and protection of workers is a high-profile safety issue at well heads, and further down the pipeline (unless the gas or oil has been ‘sweetened’). Hydrogen sulphide is a highly toxic gas which is lethal at 1,000 parts per million (or 0.1%). Traditional H2S sensors do not survive well in the hot, dry environments, increasing the risk of an accident.

The company has developed a sensor capable of operating at 70°C, improving on electrochemical technology to produce a sensor to retain moisture levels, so preventing evaporation of the electrolyte, even in the harsh Middle Eastern climate.

Crowcon's new HT H2S sensor works with the XgardIQ. The optional remote sensor housing means the sensor can be installed for optimal leak detection, while the transmitter's display screen and push-button controls are located for easy and safe to access, up to 15m away.

The technology reduces expensive maintenance downtime. A combination of high-temperatures and low humidity can cause the electrolyte to dry out in the traditional sensor design, impairing performance so they must to be frequently replaced. This incurs excessive costs in replacement sensors and in the time and manpower. The new sensor avoids this occurrence.
