I have a question regarding control on slug catchers.
I understand hat it separates liquid and gas. I have a schematic which shows a flow control valve on the liquid outlet, this is controlled by a flow controller which takes an input from a flow transmitter( on the same line) but this flow controller also takes an input from a level controller( measuring slugcatcher level). Is this just so the level in the tank is maintained at certain level in that the tank won’t empty or is there another reason?
Also with regards to the gas outlet there is a flow control valve on one line which takes an input from a flow transmitter but this flow controller also takes an input from a pressure controller which controls a valve which will send gas to a flare. Am I correct in assuming this only happens during a high pressure scenario and that during normal operations only the gas flow control valve is modulated?
Thanks
