Abstract

У заявці описано спосіб очищення потоку сирого метанолу (103), що включає наступні ступені: попередня обробка сирого метанолу на ступені відбензинювання (100) для відділення летких компонентів при певному тиску відбензинювання (р1), дистиляція метанолу принаймні на одному кінцевому ступені дистиляції метанолу при певному тиску дистиляції (р4), причому зазначений тиск (р4) вище, ніж зазначений тиск відбензинювання (р1), і при цьому газоподібний потік перегнаного метанолу (440), одержаний на кінцевому ступені дистиляції, використовують як джерело тепла принаймні частини теплового потоку для попереднього ступеня відбензинювання.
