Hi,
I'd appreciate your thoughts on the following re: double jeopardy:
Steam is flow controlled to a reboiler. Overhead gas from the column goes to a cooler, KO drum, and compressor. Excess gas to the compressor suction is vented via a pressure controller and control.
If the steam flow controller is put in manual and the valve is fully opened, there is a very significant increase in flow exiting the column. For this scenario, would it be correct to consider this flow with the compressor off and pressure controller in operation... or with the compressor off and pressure control valve fully closed?
thanks,
gpl
