Temperature and vacuum in the regeneration tower
Thread Content
I would like to ask: in the potassium carbonate production process using vacuum, lowering the temperature of the acid gas should help increase the suction at the top of the regeneration tower, is that correct?
By lowering the temperature, the volume of acidic gases decreases, the resistance to these gases in the vacuum pump is reduced, and the suction efficiency increases. As a result, the amount of acidic gases at the top of the tower does not accumulate there; consequently, the suction force at the top of the tower increases, and the temperature at that location drops slightly.
Are such questions not even considered decent these days?:'(. Why doesn’t anyone share their opinion?
Lowering the acid vapor temperature can increase the vacuum level in the regeneration tower, but it should not be made too low. It can also improve the separation efficiency of the regeneration tower, which helps to reduce hydrogen sulfide in coal gas.
