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 rate 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.

①The circulation volume of lean methanol is too low. ②The temperature of the lean methanol is too high. ③The regeneration effect is poor. ④Methanol has a low absorption capacity. ⑤Severe fluctuations in process gas flow rate
①The circulation volume of lean methanol 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.
1) The flow rate of lean methanol in the CO2 absorption tower is low. 2) The temperature for washing methanol is too high. 3) The pressure in the CO2 absorption tower is low. 4) Methanol regeneration is unsatisfactory.
Answer: ① The methanol-poor circulation rate 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 volume fluctuates violently.
