PROCESS FOR REGENERATION OF METHANOL FROM MINERALIZED WATER-METHANOL SOLUTION

摘要

A process for regeneration of methanol from a mineralized water-methanol solution comprises preheating the mineralized water-methanol solution, evaporation of water-methanol mixture therefrom, withdrawal of a saline residue, distillation of water-methanol mixture into methanol and water. Prior to preheating the mineralized water-methanol solution is subject to action of constant magnetic field, after evaporation the saline residue is supplied for recycling, and the water-methanol mixture is fed to final distillation into methanol and water, and evaporation of salts deposited on the working surfaces of equipment is carried out periodically and alternately.
