How to address the high methanol-water content in the system when starting up a low-temperature methanol washing unit? Answer: 1. Establish a methanol cycle as early as possible in the system ； 2. Start the pre-washing and regeneration system, increase the amount of methanol used for pre-washing, and raise the pre-washing load to enhance water removal. 3. System methanol dehydration is achieved by increasing the reflux methanol in the methanol water tower.
A methanol circulation system is established; the pre-washing and regeneration system is activated, the amount of methanol used for pre-washing is increased, and methanol dehydration is carried out in the system
