Abstract

Twenty-eight two-, three-, four-, and five-component amine mixtures have been evaluated as possible activators of CO 2 absorption into aqueous carbonate/bicarbonate solutions. Measurements were performed using a pressure autoclave with a sparger at conditions close to industrial ones. On the basis of these results, a formula for a new, more efficient amine activator named INS13 was developed. The activator was tested both in a pilot plant and on an industrial scale in an ammonia plant producing 300 tons/day of ammonia. Activator INS13 was applied in a number of ammonia plants in Poland and abroad.
