PROCESS CONTROL METHOD FOR EXTRACTING NATURAL GAS LIQUIDS FROM NATURAL GAS

摘要

A process is disclosed for the separation of ethane and heavier hydrocarbons or propane and heavier hydrocarbons from natural gas to provide a methane-rich natural gas stream and less volatile natural gas liquids (NGLs). This process provides for the use of a regenerable adsorbent media comprising a porous cross-linked polymeric adsorbent, a pyrolized macroporous polymer, or mixtures thereof, wherein the adsorption/desorption process is preferably continuous and is accomplished by any suitable thermal, pressure, or combination of thermal and pressure process. Further, said process comprises a feedback step for process control of the contact time between the natural gas feedstream and the adsorbent media.
