Sweet or Sour Natural Gas

Polyimide membranes for the purification of natural gas

26-Jun-2020

Natural gas that contains larger amounts of hydrogen sulfide (H2S) and carbon dioxide (CO2) is termed sour gas. Before it can enter a pipeline, it must be “sweetened” by removal of its acidic impurities. Through fine tuning of the ratios of two molecular components, it is possible to produce ...
