Can increasing the load maintain the vacuum level in the flasher?
Thread Content
There is a set of flashers used to vaporize sulfuric acid in order to separate the water. Now it is necessary to increase the load and raise the sulfuric acid feed rate. May I ask whether it is possible to maintain the original vacuum level without changing the power of the vacuum pump, by simply adjusting the valve opening (increasing the flow rate of sulfuric acid vapor)? What effect does this operation have on the vacuum level? First, I’d like to thank everyone here: lol
It depends on how much moisture is evaporated, and whether that evaporated water can be cooled before it reaches the pump. If a large amount of water vapor enters the vacuum system, it will affect the level of vacuum As for the load, it depends on the pump’s capacity; how is it performing currently? By how much does the opening increase when it is enlarged?
I agree with what moderator Mr. Xi Du said; you can try to gradually increase the load. The vacuum level may not drop within a certain range. If the load still does not meet your requirements under such conditions, you can consider adding a condenser for secondary cooling. This modification is not complicated, and it helps to minimize the entry of water vapor into the vacuum tank. However, just by increasing the load, it is not possible to ensure that the vacuum level in the tower remains constant, unless the diameter of the steam rise pipe is increased.
