How should the valves in the water system of the synthesis tower be set for operation before Cat heating and reduction? Answer: (1) Open the drum vent valve ； (2) All valves of the drum pressure control valve are closed ； (3) The isolation valves before and after the feed water control valve on the drum, as well as the bypass and drain valves, are all closed ； (4) Drain valves on the shell side of the steam drum and synthesis tower are closed ； (5) Use a desalinated water pipeline to supply desalinated water to the steam drum ； (6) Close the steam valve leading to the injector.
