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.
Claims30
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.
A pressure swing adsorption system, the system comprising:
- a plurality of adsorbent beds, the adsorbent beds comprising adsorbents comprising carbon, wherein the pressure swing adsorption system is operable to continuously and simultaneously separate components of a raw natural gas stream into a substantially pure methane stream and a product stream being substantially comprised of components with a greater molecular weight than methane.
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.
A pressure swing adsorption system, the system comprising:
- a plurality of adsorbent beds, wherein the pressure swing adsorption system is operable to continuously and simultaneously separate components of a pressurized feed gas stream into a substantially pure target hydrocarbon stream and a product stream being substantially comprised of components with a greater molecular weight than the target hydrocarbon stream.
