A B S T R A C T A system is described for removing CO2 from the manufactured process gas in an SNC manufacturing plant, the system operating the hot carbonate process wherein hot potassium carbonate solution absorbs CO2 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 (Figure 2) 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 SNC plants. For this purpose the system includes a solution make up tank 30, a solution storage tank 31, and a flushing water collection tank 32, preferably has all of its surfaces contacted by potassium carbonate solution made of stainless steel, and has sensors (F, L, T, P, AN, SG, and PH) and valve switches for transmitting information to the computer relating to the state of the system. The computer is programmed to operate the sequences of operation necessary to achieve the start up, running and shut down of the system, operate loop controls on the solution levels in the absorber and regenerator columns, and on the rates of flow of solution to the absorber and of steam to the reboiler, and also to monitor the system parameters and to display data and signal alarm conditions.
