Most PPCL monthly webinars are in the category "Operating Envelopes 101 – part 1" because they are based on continuous processes where the continuous operation Mode can be described with a single Operating Envelope.
| There will be four sessions to suit different time-Zones so choose the one closest to your time-zone and click on the appropriate link below to enrol. The webinars are listed by BST(British Summer Time) which is GMT+!.
6 AM BST Wednesday 29 June: UK (BST) 600, Dubai 900. Mumbai (IST) 1030, Perth 1300, Sydney/Brisbane 150 A Recording of one of the Sessions will be available after the webinar but it will not include the live Q&A Session.  |
"This is important because for many attendees our webinars are their first introduction to the sheer power of the Geometric Process Control (GPC) method based on parallel coordinates, n-dimensional geometry and multi-dimensional Operating Envelopes and Human Intelligence. And it is all available now so bring your process operations problems to us, whether you judge them be easy or hard, and we will show you how to solve them," said a spokesman for Process Plant Computing Limited (PPCL) the organisers.
Many real processes such as batch, fed-batch, cyclic, grade-change and all sorts of non-continuous processes require more than one Operating Envelope and that’s what this webinar will introduce. Envelopes can be made time-dependent by including time variables but even without a time variable it can be remarkable how models can cope with a changing relationship effectivel inferring time. Even continuous processes really have more than one operating Mode such as Start-Up and Shut-Down as well as Modes for Standby, different throughputs and Special Modes for, for instance, catalyst regeneration.
"You’ve probably seen batch processes controlled by trying to follow a defined trajectory on a very small number of variables such as reactor temperature or concentration. We will show you versions of models with and without time variables which may give you food for thought."
Operating Envelopes linked to form a chain allow control of the process into a multi-variable tube of hundreds of variables instead of just one or two and since the tube includes Result-variable range predictions find one or a chain of Operating Envelope better at recognising external disturbances and guiding the operation to achieve the desired end-points.
"A Golden Batch every time is our ambition! Come and see how it is done by enrolling on this webinar," concluded the spokesman.
