Process for Recovering Olefins from Manufacturing Operations |
摘要 |
A process for treating an effluent gas stream arising from a manufacturing operation that produces an olefin or an olefin derivative. The process involves compressing the feed gas stream, which comprises an olefin, a paraffin, and a third gas, to produce a compressed stream, then cooling and condensing the compressed stream. The condensation step produces a liquid condensate and an uncondensed gas stream. The liquid condensate is then passed through a membrane separation step. The membrane separation of the condensate results in an olefin-enriched stream, which may be recycled for use within the manufacturing operation, and an olefin-depleted stream, which may be purged from the process. |

1. A process for treating an effluent gas stream arising from an operation that manufactures an olefin or an olefin derivative, said effluent gas stream comprising an olefin, a paraffin and a third gas, the process comprising the steps of:
(a) passing said effluent gas stream to a compressor to produce a compressed stream; (b) partially condensing the compressed stream, including cooling and separating the compressed stream into an uncondensed gas stream depleted in olefin and paraffin and a condensed liquid condensate enriched in olefin and paraffin; and (c) separating the condensed liquid condensate using a first membrane to produce a first olefin-enriched permeate stream and a first olefin-depleted residue stream. |
