EN

A long-term cooperation situated in the coke oven gas processing sector with several sequel and sub-sequel 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 plant and further experiments are presented, as well as the results of additional sub-projects including foaming, membrane separation and cost optimisation.

PL

Omówiono projekty kolejno tworzone w sektorze obróbki gazu w piecu koksowniczym powstające w wyniku współpracy między uczelnią a przedstawicielami przemysłu. Opisano nierównowagowy model chemicznej absorpcji i desorpcji kwaśnych gazów w kolumnach dla procesu (proces AS) oraz stosowany układ elektrolitów i współczynnik wzmocnienia. Przedstawiono zarówno doświadczalną atestację w instalacji i inne doświadczenia, jak i wyniki dodatkowych badań dotyczących powstawania piany, separacji membranowej i optymalizacji kosztów.
