ABSTRACT:
An improved process for recovering hydrocarbon components from a hydrocarbon-carrier gas mixture wherein the mixture is passed through a solid adsorbent bed capable of selectively adsorbing the hydrocarbon and passing substantially hydrocarbon-free carrier gas. The hydrocarbon components are recovered by passing a hydrocarbon-rich flushing gas mixture through the adsorbent bed followed by subjecting the adsorbent bed to a change in pressure to desorb the hydrocarbon components and produce a hydrocarbon-rich product stream. Further hydrocarbon enrichment may be obtained by passing the product stream to another solid adsorbent bed to adsorb the hydrocarbon and pass further substantially hydrocarbon-free carrier gas. The hydrocarbon components are then recovered by subjecting the other adsorbent bed to a vacuum to desorb the hydrocarbon and produce a richer hydrocarbon product stream.
