Abstract
Hydrocarbon processing systems and a method for liquefied natural gas (LNG) production are described herein. The hydrocarbon processing system includes a fluorocarbon refrigeration system configured to cool a natural gas to produce LNG using a mixed fluorocarbon refrigerant and a nitrogen rejection unit (NRU) configured to remove nitrogen from the LNG.
Claims26
A hydrocarbon processing system for liquefied natural gas (LNG) production, comprising:
- a fluorocarbon refrigeration system configured to cool a natural gas to produce LNG using a mixed fluorocarbon refrigerant;
- and
- a nitrogen rejection unit (NRU) configured to remove nitrogen from the LNG.
A method for liquefied natural gas (LNG) production, comprising:
- cooling a natural gas to produce LNG in a fluorocarbon refrigeration system using a mixed fluorocarbon refrigerant;
- and
- removing nitrogen from the LNG in a nitrogen rejection unit (NRU).
A hydrocarbon processing system for formation of a liquefied natural gas (LNG), comprising:
- a mixed refrigerant cycle configured to cool a natural gas using a mixed fluorocarbon refrigerant, wherein the mixed refrigerant cycle comprises a heat exchanger configured to allow for cooling of the natural gas via an indirect exchange of heat between the natural gas and the mixed fluorocarbon refrigerant;
- a nitrogen rejection unit (NRU) configured to remove nitrogen from the natural gas;
- and
- a methane autorefrigeration system configured to cool the natural gas to produce the LNG.
