How does the VaporSep® process work?
The VaporSep process combines a compression-condensation step with a membrane separation step. The feed gas – a mixture of hydrocarbons in nitrogen, hydrogen, or methane – is compressed and cooled, condensing a portion of the hydrocarbons in the gas. The liquid hydrocarbons are recovered; the remaining gas, which still contains significant amounts of hydrocarbons, is fed to the VaporSep membrane. The membrane separates the gas into a hydrocarbon-rich permeate stream and a hydrocarbon-depleted residue stream (the purified gas). The permeate is recycled to the compressor; the residue stream is vented or reused.
