甲醇气相脱水制二甲醚工业实践

Industrialization of preparing dimethyl ether by gaseous phase dehydration of methanol

通过对1万t.a-1甲醇气相脱水制二甲醚工业装置的模拟计算,在装置不做大的改动的情况下,使用粗甲醇代替精甲醇为原料生产二甲醚,装置达到了同等的生产规模。

The industrialization of preparing dimethyl by 10000t . a^-1 gaseous phase dehydration of methanol was analog calculated. The same production capacity was obtained by using impure methanol instead of pure methanol.
