| titleOfInvention | Method for cooling in distillation and polymerisation process by absorption refrigeration |
| abstract | The present invention relates generally to olefin polymerization. In particular, the present relates to a process for the separation of a hydrocarbon-containing feed stream (20) comprising the steps of: (a) optionally cooling said hydrocarbon-containing feed stream (20) using an absorption refrigeration cycle (37), (b) introducing said feed stream (20) into a first distillation zone (22) for subjecting said feed (20) to distillation conditions adapted to remove b1) a bottom stream (25) comprising co-monomer, and b2) an overhead stream (29) comprising hydrocarbon diluent, olefin monomer and further components such as H2, N2, O2, CO, CO2, and formaldehyde, and (c) introducing the overhead stream (29) of step b) in a second distillation zone (23) for subjecting said stream (29) to distillation conditions adapted to remove c1) a bottom stream (30) comprising substantially olefin-free hydrocarbon diluent, c2) a side stream (31) comprising hydrocarbon diluent, and c3) an overhead vapor stream (32) comprising olefin monomer, diluent and further components such as formaldehyde, H2, N2, O2, CO and CO2, and (d) cooling the temperature of said removed overhead vapor stream (32) using an absorption refrigeration cycle (34) prior to separating (35) said olefin monomer from said diluent in said overhead vapor stream (32). Said invention also relates to a polyolefin production process and to a polyolefin production unit. |
