A process is provided to separate a hydrocarbon stream comprising a mixture of light olefins and light paraffins, the process comprising sending the hydrocarbon stream through a pretreatment unit to remove impurities selected from the group consisting of sulfur compounds, arsine, phosphine, methyl acetylene, propadiene, and acetylene to produce a treated hydrocarbon stream; vaporizing the treated hydrocarbon stream to produce a gaseous treated hydrocarbon stream; adding liquid or vapor water to the gaseous treated hydrocarbon stream; then contacting the gaseous treated hydrocarbon stream to a membrane in a membrane system comprising one or more membrane units to produce a permeate stream comprising about 96 to 99.9 wt % light olefins and a retentate stream comprising light paraffins.

Membrane process for olefin separation

An apparatus and process for stripping gases from solids comprises a structured packing in a stripping section of a vessel. The structured packing comprises a plurality of corrugated ribbons with each corrugated ribbon having at least two faces angular to each other. The ribbons at least partially obstruct passage of the solid particles. Edges of adjacent ribbons defining openings for the passage of contacted particles.
