HYDROCARBON RECOVERY FROM CARBON DIOXIDE-RICH GASES

摘要

ABSTRACTA process is set forth for the separation of carbon dioxide frompropane and higher alkanes using a carbon dioxide-loaded lean oil solventand higher solvent flows and heat utilizations rather than mechanicalenergy utilization, A high pressure carbon dioxide product is produced,making the invention valuable in carbon dioxide miscible flood enhancedpetroleum recovery operations.
