Abstract

Способ дистилляции потока сырого метанола, полученного из синтез-газа, в дистилляционной колонне, причем указанный сырой поток содержит сивушное масло и щелочь, сивушное масло удаляют из дистилляционной колонны в виде парового бокового погона, отводимого из дистилляционной колонны ниже точки подачи сырья, и паровой боковой погон практически не содержит щелочи. Также описан способ получения метанола с использованием этого способа дистилляции.
