  • Automatic CO.sub.2 removal system and operation thereof
    Patent number: 4491566
    Abstract: A system is described for removing CO.sub.2 from the manufactured process gas in an SNG manufacturing plant, the system operating the hot carbonate process wherein hot potassium carbonate solution absorbs CO.sub.2 from the process gas under pressure in an absorber column 1 and is regenerated by pressure reduction and steam stripping in a regenerator column 14 and a reboiler 17 before being returned to the absorber by a circulating pump 7. The system is completely automated and is controlled by a computer so that start-up, running and shut-down of the system is carried out automatically upon initiation by an operator, whereby the system is particularly suited for use in peak load SNG plants.
