Medium pressure steam header operating at 42 bar.
Presuure loop comprises 2 6inch control valves venting to atmosphere. Valves are presently split ranged.
When an upstream consumer trips, 70tonnes of steam are required to be vented, with minimum disturbance to the header pressure.
What is the most effective control strategy to cater for this scenario. Logic tunable controller parameters? Any suggestions please.
