Abstract:
A method for conditioning natural gas into fuel gas, where the method includes the step of: delivering a natural gas stream including both CO 2 and C2+ hydrocarbons to a membrane separation assembly; and separating the natural gas stream into the following streams: (i) a first permeate stream, (ii) a second permeate stream, and (iii) a residual stream. The first permeate stream includes CO 2 removed from the natural gas stream. The second permeate stream includes methane at a greater concentration than a concentration of methane in the natural gas stream. The residual stream contains C2+ hydrocarbons at a greater concentration than a concentration of C2+ hydrocarbons in the natural gas stream.
Abstract:
A method and apparatus to reduce SO 2 emissions by gas membrane separation and liquid carrier chemical absorption. The membrane separation system consists of an absorption system containing ceramic membranes through which is circulated an aqueous NaOH absorbent carrier. Exhaust gases contact the exterior surface of the membranes and the target gasses permeate the membrane wall and are absorbed by the carrier within the bore and thereby are removed from the exhaust stream. Regeneration of the NaOH absorbent carrier is carried out using an electrolyser and regenerated aqueous NaOH is recirculated back into the bore.
Abstract:
A highly cost-efficient method and process for producing oxygen from a gaseous mixture such as air results in substantial energy savings compared to conventional methods. The gaseous mixture is led to a membrane absorber in which oxygen from the gas is absorbed through a first membrane by an oxygen -absorbing liquid that possesses suitable absorption and desorption properties. The resulting oxygen-rich carrier liquid is led to a membrane desorber in which oxygen from the liquid is desorbed through a second membrane, suitably with the aid of a vacuum. The oxygen product suitably has greater than 95% purity, or greater hum 99% purity.
