Absorber calculations – How to calculate recirculating absorption?
Thread Content
Water is used to absorb HCL; the liquid at the bottom of the tower is circulated to the top of the tower for absorption, with water being added to the bottom of the tower. How should this absorption tower be designed, given that the liquid at the top of the tower is the circulating fluid and the concentration of HCL in the incoming gas is 0.8%?
Why is it necessary to add water to the tower bottom? ? Isn’t the top-of-tower water replenishment more effective? ? What do you want to calculate? HCL concentration in the flue gas at the top of the tower? Is it the hydrochloric acid concentration at the bottom of the tower? 》
The absorbent solution is recycled for absorption; in conditions where heat release is not significant, this approach results in higher consumption compared to the use of a cloth filter
