Abstract
A non-cryogenic system for gas separation includes an absorbent system for removing condensable hydrocarbons from a feed gas. The feed gas is then directed into a gas-separation membrane. The absorbent system includes a liquid absorbent having an affinity for hydrocarbons. The liquid absorbent can be, for example, compressor oil or mineral oil. A chiller and a carbon bed may optionally be positioned between the absorbent system and the membrane. The absorbent is periodically regenerated by reducing the pressure or increasing the temperature of the liquid.
Claims18
A non-cryogenic gas-separation system comprising:
- a) means for providing a feed gas containing a condensable hydrocarbon,
- b) an absorbent system connected to receive the feed gas, the absorbent system comprising a liquid hydrocarbon having affinity for other hydrocarbons, and
- c) a gas-separation membrane module connected to receive an output stream of the absorbent system.
A method for non-cryogenic separation of a feed gas containing a condensable hydrocarbon, the method comprising the steps of:
- a) passing a feed gas containing a condensable hydrocarbon through a liquid absorbent, to produce a gas stream having a reduced content of condensable hydrocarbons, and
- b) directing said gas stream into a gas-separation membrane for separating the gas stream into components.
A method for non-cryogenic separation of a feed gas containing a condensable hydrocarbon, the method comprising the steps of:
- a) bubbling a feed gas through a liquid hydrocarbon selected from the group consisting of compressor oil and mineral oil, to produce a gas stream having a reduced content of condensable hydrocarbons, and
- b) directing said gas stream into a gas-separation membrane for separating the gas stream into components.
