Patent number: 9908078Abstract: Methods and systems of enhanced carbon dioxide recovery from an inlet gas stream are provided, by introducing the gas stream to one or more membrane-based separation units to produce a permeate byproduct gas stream having increased concentration of carbon dioxide compared to the inlet gas stream and then introducing the permeate byproduct gas stream to one or more pressure swing adsorption units or trains to enhance recovery of hydrocarbons, such as methane, lost in the byproduct stream and to produce a substantially pure carbon dioxide stream, while minimizing process compression and eliminating process heat for process regeneration. The methods introduced herein are for enhancing product recovery by enhancing carbon dioxide recovery from gas streams with pressures greater than atmospheric conditions.

Publication number: 20160200592Abstract: A method for removing acid-gases from water includes introducing acid into a flow of aqueous solution having acid-gases and associated conjugate bases having an initial pH to lower the pH. The lowered pH solution has a stripping gas passed therethrough, resulting in a vapor phase of liberated acid-gas and stripping gas vapors, and a liquid phase comprising a lower concentration of acid-gases and associated conjugate bases than the aqueous solution. The liberated acid-gas and stripping gas vapors are collected and treated to remove acid-gas components, resulting in clean stripping gas product. The liquid phase is separated and collected with a second treating step, resulting in a final aqueous product having a lower concentration of acid-gases and associated conjugate bases than the liquid phase.Type: ApplicationFiled: January 12, 2016Publication date: July 14, 2016Applicant: Apache CorporationInventors: Christopher M.
