Catalytic shutdown treatment
Thread Content
Before cleaning the various side lines during the shutdown of the distillation tower, must the oil, gas, and water cooling system at the top of the distillation tower be shut off?
During the side line purging, oil-gas-water cooling does not need to be disconnected; however, when purging the oil and gas pipelines, it is necessary to open the drain on the water side of the cooler before proceeding with the purging.
Like other water coolers, there is no need to cut anything off; it is sufficient to cut off the tube side and vent it to prevent pressure buildup. .
Is the poster planning to stop working? I don’t know which one it is
This depends on your actual situation; in fact, water cooling is quite flexible. First, to ensure an effective purging effect, the cooler can be switched for purging intermittently ； Secondly, to ensure that the anti-corrosion coating of the anti-corrosion cooler does not peel off, intermittent purging is also necessary. Thirdly, if the cooler is in use for a long time and all the steam is condensed, the purging effect in the subsequent stage will be reduced. It depends on your situation.
If it isn’t removed, will it only affect the purging effect?
It also affects the cooler; either it’s anti-corrosion pipes, or in severe cases, water hammer occurs.
Removal is also an option; it’s hardly used during purging, and is mainly utilized in the distillation tower
