CARBON DIOXIDE LIQUEFACTION SYSTEM

摘要

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).
