Abstract

В заявке описан способ удаления диметилового эфира из потока, включающего этилен и/или пропилен. Диметиловый эфир удаляют под низким давлением, предпочтительно в дистилляционной колонне. Преимущество разделения под низким давлением состоит в том, что обеспечивается возможность выделения при относительно низкой температуре при одновременной возможности выделения высококонцентрированного потока этилена и/или пропилена.Международная заявка была опубликована вместе с отчетом о международном поиске.The application describes a method for removing dimethyl ether from a stream comprising ethylene and / or propylene. Dimethyl ether is removed under low pressure, preferably in a distillation column. The advantage of separation under low pressure is that it is possible to release at a relatively low temperature while at the same time allowing a highly concentrated stream of ethylene and / or propylene to be released.
