How do VaporSep membranes work?
VaporSep membranes separate gas mixtures on the basis of solubility. Large hydrocarbon molecules with greater solubility in the membrane permeate much faster than smaller, less soluble molecules such as nitrogen, hydrogen, or methane. By comparison, conventional membranes separate gases on the basis of size. Small molecules are selectively permeated because they diffuse through the membrane more rapidly than large molecules.
