What are the factors affecting the pressure in the dry gas desulfurization tower, and what are the methods for adjusting it?
Thread Content
1) Influencing factors a) Changes in dry gas volume. b) Changes in the pressure of the high-pressure gas pipeline network. c) Instrument failure. (2) Regulation method a) Contact the stable position control to stabilize the dry gas flow rate. b) Contact the dispatch team to relieve pressure in the gas pipeline network. c) If the instrument fails, switch to manual or backup control immediately, and contact the instrumentation technician for repair.
