Original post:‘s Greg McMillan will be conducting his 8th demo/seminar (a.k.a. deminar) tomorrow, August 25. The topic will be PID Control of Runaway Processes. It will be on-line and live across the internet at 10:00 am CDT / 15:00 UTC. To attend the event, go to . Use the information below to connect (if you’re not using the available computer audio):

Runaway processes are found in highly exothermic reactors used to produce polymers and specialty chemicals. The chemical reaction rates increase with temperature. Tight control is critical for safety, quality, production rate, and batch cycle time. Tuning these temperature loops with conventional tuning rules can cause excessive oscillations, overshoot, and potential emergency shutdown (ESD) trips.

Other runaway processes include some biological reactions, acids and bases, and axial compressor speed control during surge conditions to name a few.

If you have runaway processes in your plant, you’ll want to join us tomorrow and hear Greg share his experiences in how to best address and control these processes.

If you’ve not attended any of Greg’s deminars to this point, we record and archive them for future viewing. Here’s the links to the recorded videos and presentations for the deminars to date:
