This article introduces the production process of methanol from coke oven gas,in which the distillation process utilizes the low-level waste heat of the converted gas as energy to refine crude methanol and produce high-purity refined methanol.By effectively utilizing the waste heat from the conversion wastewater after stripping in the conversion stripping tower as the heat source for crude methanol entering the preheater of the distillation tower,comprehensive utilization of the waste heat from the conversion gas can be achieved,and high-purity refined methanol products can be separated.
