NXT Gas Solutions offers natural gas membrane systems through its exclusive relationship with Air Liquide. Membrane systems for natural gas treatment have been used since the 1980s. The membrane process is inherently simple. Air Liquide's hollow fiber membrane technology addresses a broad range of natural gas conditioning needs, including water and hydrocarbon dew point control, acid gas removal (CO2 and H2S), nitrogen removal and Natural Gas Liquids (NGLs) recovery. Air Liquides PEEK membranes are not affected by solvents and chemicals typically present in natural gas.
