Recovery of hydrocarbons from polyalkene product purge gas |
| abstract |
Hydrocarbons are recovered from the product purge gas (23) in an alkene polymerization process by absorption (117) of heavier hydrocarbons from the purge gas by an intermediate hydrocarbon stream (31) to yield a vapor (35) rich in inert gas and alkene monomer. Alkene monomer (37) is condensed (121) at low temperatures from the inert gas (45), flashed and vaporized (41) to provide refrigeration for the condensation step, and recycled (5) to the polymerization process. The intermediate hydrocarbon from the absorption step (117) is recycled (33) to the polymerization process. Optionally a portion of the inert gas (49) is reused for purge gas. n When the heavier hydrocarbon content of the product purge gas (23) is soluble in the condensed monomer and intermediate hydrocarbon liquids, the absorption step (171) can be omitted and the purge gas passed directly (30) to the condensation step (121). |
