  A high cyclic capacity carbon dioxide scrubbing process contacts a gas stream containing carbon dioxide in a sorption zone with a liquid scrubbing solution of a low molecular weight sterically hindered amine, particularly a secondary alkanolamine or aminoether at a high concentration, typically at least 3.5M and at a temperature of at least 30° C. to sorb the carbon dioxide into the solution and form a rich stream of the sorbed carbon dioxide in the solution in the form of dissolved amine carbamate and/or alkanolamine bicarbonate. The rich stream is then passed from the sorption zone to at least one regeneration zone and the sorbed carbon dioxide is desorbed as gas from the solution to form a lean solution containing a reduced concentration of sorbed carbon dioxide relative to the rich stream; the lean stream is then returned to the sorption zone for a further sorption cycle.
