In order to ensure the balance of the H2O-NH3-H2S-CH3OH system in the low-temperature methanol washing process,the impact of the imbalance of various factors in the system on the system operation was studied.By analyzing the reaction mechanism and source of ammonia and hydrogen sulfide in methanol in the system,methanol was expounded.The harm caused by poor quality to the low-temperature methanol washing system is proposed.Optimization measures are proposed to deal with excessive ammonia and sulfide in lean methanol.This provides a basis for improving the desulfurization and decarbonization effect of the low-temperature methanol washing system and solves the impact of poor quality of lean methanol on system operation.It also affects the operation of the system.Provide theoretical basis for the smooth operation of coal chemical equipment.
