Beschreibung
Zusammenfassung:	A portable pressure swing adsorption method and system for low flow rate gas processing. A method of processing of hydrocarbon gas includes feeding hydrocarbon gas through a first adsorption bed of a pressure swing adsorption system, recovering light product from the first adsorption bed during the feed time, obtaining heavy product from a second adsorption bed during the feed time, wherein the second adsorption bed depressurizes to about vacuum during the feed time, compressing the heavy product to obtain natural gas liquid and vapor, sending a volume of reflux gas through the first adsorption bed after the feed time to obtain additional light product, and adjusting the feed flowrate, the feed time, or the volume of reflux gas based on a gross heating value of the feed gas, wherein adjusting the volume of reflux gas includes combining NGL storage tank vapor with the reflux gas.
