Sudden rise in liquid level in the oil-gas separator of the catalytic fractionation tower
Thread Content
The liquid level in the oil-gas separator of the catalytic fractionation tower rises suddenly, and the crude gasoline pump becomes evacuated – how should this be handled and what precautions should be taken?
It’s necessary to determine the specific cause: is it vacuum formation at the top of the fractionation tower, an increase in the temperature at the top of the fractionation tower, a high level in the separator, vacuum formation in the crude gasoline pump, or is it an artificial level reading?
Switch to the backup pump immediately, adjust the operation of the absorption stabilization system, and finally identify the cause of the evacuation.
Based solely on the symptoms, it is possible that the pump inlet is blocked, assuming that instrument issues are ruled out.
Find out what caused the pump to go into vacuum
Quickly switch to the backup pump and adjust the operation to ensure stable absorption. If the standby pump also becomes empty, slowly release air at the pump inlet to see if overheating is causing vaporization. Find the cause. . . .
We discussed this when drafting the operating procedures: \"What should be done if both crude gasoline pumps stop working?\" ”:lol
Nothing works now; it’s dangerous to drain it into the sink. 1. If the reaction rate decreases, cut off the feed immediately. 2. Start two acid water pumps to pump crude gasoline. 3. Stop the air compressor
The temperature is too low after cooling, causing the hydrocarbons to vaporize
