Abstract
Systems are disclosed herein for enhancing energy usage while pressurizing a carbonaceous gas. Such systems include a carbon dioxide (CO2) liquefaction system. The CO2 liquefaction system includes a first cooling system capable of cooling a CO2 gas to liquefy greater than approximately 50 percent of the CO2 gas. The first cooling system produces a first CO2 liquid. The CO2 gas pressure is less than approximately 3450 kilopascals (500 pounds per square inch absolute).
Claims20
A system, comprising:
- a carbon dioxide (CO2) liquefaction system, comprising:
- a first cooling system configured to cool a CO2 gas to liquefy greater than approximately 50 percent of the CO2 gas to produce a first CO2 liquid, wherein the CO2 gas pressure is less than approximately 3450 kilopascals (500 pounds per square inch absolute).
A system, comprising:
- an air separation unit comprising a cryogenic cooling system, wherein the air separation unit is configured to separate air into oxygen and nitrogen;
- and
- a liquefaction system configured to cool a carbonaceous gas with the cryogenic cooling system of the air separation unit, wherein the cryogenic cooling system is configured to liquefy at least a first portion of the carbonaceous gas to produce a first carbonaceous liquid.
A system, comprising:
- a carbon capture system configured to capture a carbonaceous gas from a synthetic gas;
- and
- a liquefaction system, comprising:
- a first cooling system configured to cool the carbonaceous gas to liquefy at least a first portion of the carbonaceous gas to produce a first carbonaceous liquid and a first residual carbonaceous gas;
- and
- a compression system configured to compress the first residual carbonaceous gas.
