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. 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 sharply.
The flow rate of lean methanol is too low, the temperature of the lean methanol is too high, resulting in poor regeneration efficiency
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 sharply.
I really want to know what the correct answer is? Can I take a look?
The temperature of lean methanol is high, and the volume of shift gas increases

(1) The circulation rate of lean methanol is too low； (2) The temperature of lean methanol is too high ； (3) Poor regeneration effect ； (4) Low methanol absorption capacity ； (5) Severe fluctuations in process gas flow rate
①Too low circulation rate of lean methanol ② Too high temperature of lean methanol ③ Poor regeneration efficiency ④ Low methanol absorption capacity ⑤ Severe fluctuations in process gas flow rate
