Abstract
A method for separation of dimethyl ether from reactive mixture by the way of rectification in the column under pressure with dimethyl ether take-off, at that from the reactive mixture before the feed into rectification column the dissolved gases are removed in refining stripper. This method allows to reduce the carbon dioxide content in final product from 1.5 mas.% to 0.04 mas.% and increase the output of dimethyl ether.
