PROCESS FOR RECYCLING PRODUCT STREAMS SEPARATED FROM A HYDROCARBON-CONTAINING FEED STREAM |
摘要 |
<p>The present invention relates to a process for recycling product streams that have been separated from a hydrocarbon-containing feed stream comprising olefin monomer, olefin co-monomer, hydrocarbon diluent and components such as 112. N. O2. CO. CO2. and formaldehyde. In accordance with the present process a hydrocarbon-containing Iced stream is separated into a) a first side stream comprising hydrocarbon diluent and olefin monomer; b) a second side stream which is substantially hydrogen-free and comprises hydrocarbon diluent and olefin monomer, c) a bottom stream comprising substantially olefln-free hydrocarbon diluent, and d) an overhead vapor stream comprising olefin monomer, hydrocarbon diluent and components such as formaldehyde. 112. N2. O2. CO and CO2. The present process further includes recycling said first and said second side streams in a polymerization process for preparing bimodal polyolefin.</p> |
