This post was last edited by hai8487 on 2017-8-18 09:37. What are the reasons for excessive carbon dioxide levels in the purified gas coming out of the methanol scrubber? Answer: ① The methanol-poor circulation volume is too low. ②The temperature of the lean methanol is too high. ③The regeneration effect is poor. ④Methanol has a low absorption capacity. ⑤The process gas flow rate fluctuates sharply.

The flow rate of lean methanol is too low. The temperature of the lean methanol is too high. The regeneration effect is poor. Methanol has a low absorption capacity. Severe fluctuations in process gas flow rate
(1) The circulation rate of lean methanol is too low； (2) The temperature of lean methanol is too high ； (3) The regeneration effect is poor ； (4) Low methanol absorption capacity ； (5) Severe fluctuations in process gas flow rate.
