In the wastewater discharged from the bottom of the methanol-water distillation tower, it is desirable for the methanol content to be as low as possible. （） 2. The methanol used in the low-temperature methanol washing spray should be introduced first, so as to create a certain layer of methanol liquid within the pipes and the heat exchangers surrounding the feed gas. This helps to thoroughly wet the pipes and their walls, ensuring that condensate water and methanol can mix thoroughly everywhere after the gas is introduced.
