PROCESS FOR CATALYTIC CRACKING OF A HEAVY HYDROCARBON CLEARING FEED AND OBTAINING LIGHT OLEFINS SUBSTANTIALLY FREE OF CARBON DIOXIDE, AND SYSTEM FOR CATALYTIC CRACKING OF A HYDROCARBED LEADING HYDROCARBON FEED

摘要

Processing schemes and arrangements for the amine treatment of high olefin content (e.g., ethylene-rich) carbon dioxide-containing streams such as for the effective separation and removal of carbon dioxide therefrom are provided. Corresponding or associated processing schemes and arrangements for the catalytic cracking of a heavy hydrocarbon feedstock and obtaining light olefins substantially free of carbon dioxide via absorption-based product recovery are also provided.
