Handling of compressed rich gas interruption
Thread Content
What should be done with the fractionation tower section after the compression rich gas supply to the catalytic cracking unit is interrupted? Please be detailed
Close the hand valve for compressed rich gas to the air cooler and the hand valve for wash water； Control the normal pressure of the three towers; if the pressure drops, the outlet valves for each medium can be closed ； Adjust the liquid levels in each tower and tank in a timely manner to maintain normal operation ； Adjust the temperatures of each tower in a timely manner to maintain the temperatures and pressures of both towers ； If compressed rich gas supply cannot be restored for an extended period, the refining of crude gasoline can be switched to, and the pumps in the system should be stopped to maintain various liquid levels and pressure.
