Abstract
Methods and systems for continuous pressure swing adsorption separation of a pressurized feed gas stream, the method including separating hydrocarbons heavier than methane from the pressurized feed gas stream to produce at least two product streams, a first product stream being substantially pure methane, and a second product stream being substantially comprised of components with a greater molecular weight than methane.
Claims21
A method for continuous pressure swing adsorption separation of a pressurized feed gas stream, the method comprising the step of:
- separating hydrocarbons heavier than methane from the pressurized feed gas stream to produce at least two product streams, a first product stream being substantially pure methane suitable for transport by natural gas pipeline, and a second product stream being substantially comprised of components with a greater molecular weight than methane, where the first product stream has a recovery percentage of at least about 90 mol. % of the methane from the pressurized feed gas stream.
A method for continuous pressure swing adsorption separation of a pressurized feed gas stream, the method comprising the step of:
- separating hydrocarbons heavier than a target hydrocarbon from the pressurized feed gas stream to produce at least two product streams, a first product stream being substantially pure target hydrocarbon, and a second product stream being substantially comprised of components with a greater molecular weight than the target hydrocarbon, where the first product stream has a recovery percentage of at least about 90 mol. % of the target hydrocarbon from the pressurized feed gas stream.
