Rate-based model for chemical absorption and desorption developed in cooperation between the university and the industry in the coke oven gas purification sector

摘要

A long-term cooperation situated in the coke over gas processing sector with several sequel and subsequel projects is described.A non-equilibrium model for chemical absorption and desorption of sour gases in columns within the ammonia-hydrogensulphide circulation scrubbing process (AS-process) is presented in detail including the electrolyte system and the enhancement factors used.In addition,the experimental validation in a pilot and further experiments are presented,as well as the results of additional sub-projects including foaming,membrane separation and cost optimisation.
