PROCESS FOR PRODUCING OLEFINS |
摘要 |
<p>A process is described for producing an olefins stream from a first vapor effluent stream from an oxygenate to olefin conversion reaction, said first vapor effluent stream comprising C<SUB>2 </SUB>and C<SUB>3 </SUB>olefins, C<SUB>4 </SUB>hydrocarbons, and C<SUB>2 </SUB>to C<SUB>6 </SUB>carbonyl compounds. In the process, the temperature and pressure of the first vapor effluent stream are adjusted to produce a second vapor effluent stream having a pressure ranging from about 100 psig to about 350 psig (790 to 2514 kPa) and a temperature ranging from about 70° F. to about 120° F. (21 to 49° C.), said second vapor effluent stream containing about 50 wt. % or more C<SUB>4 </SUB>hydrocarbons based upon the total weight of C<SUB>4 </SUB>hydrocarbons in the first vapor effluent stream. The second vapor effluent stream is then washed with a liquid alcohol-containing stream to produce a third vapor effluent stream, whereafter the third vapor effluent stream is washed with liquid water to provide a fourth vapor effluent stream comprising the C<SUB>2 </SUB>and C<SUB>3 </SUB>olefins and about 1.0 wt. % or less C<SUB>2 </SUB>to C<SUB>6 </SUB>carbonyl compounds.</p> |
