Title: Design of packed towers for absorption and desorption of carbon dioxide using hot promoted K2CO3 solution
Authors: Rao, D Phaneswara

Issue Date: 1991

Abstract: The mathematical model developed for the design of a packed column for the absorption of carbon dioxide in hot promoted potassium carbonate solution (Gas Sep Purif (1989) Vol 3 p 152; (1990) Vol 4 p 58) is extended to take into account the condensation of water present in the gas feed to the absorption column. The revised model is further extended to obtain the design of the desorption column where the feed gas is pure steam and the exit gas consists of carbon dioxide and steam. The integration of the relevant differential equations for the desorption tower is done by starting the calculations from the top conditions of the column where the exit flow rate of steam and exit gas temperature are guessed and verified later after completing the tower calculations with the help of the overall material and energy balance calculations.
