ABSTRACT:
A process for extracting natural gas liquids (NGLs) from natural gas that involves contacting natural gas from one source with crude, or heavy, oil from a different source under conditions that promote enrichment of the crude or heavy oil with NGLs from the natural gas. Apart from functioning as an absorbent fluid, the crude or heavy oil also functions as the carrier medium for the absorbed. NGLs. When practicing the process, unlike conventional methods, there is no need to regenerate the absorbent fluid, in this case the crude and heavy oil, for recycling.
