What are the reasons that can cause an excess level of carbon dioxide in the purified gas coming out of the methanol washing tower? 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 severely.

Answer: 1. The circulation volume of lean methanol is too low. 2. The temperature of the lean methanol is too high. 3. The regeneration effect is poor. 4. Low methanol absorption capacity. 5. Severe fluctuations in process gas flow rate.
①The flow rate of lean methanol is too low. ② The temperature of the lean methanol is too high. ③ The regeneration effect is poor. ④ The methanol absorption capacity is low. ⑤ The flow rate of the process gas fluctuates sharply
