Modellierung des Wasserwaschsystems von Destillationssystemen in katalytischen Krackanlagen

Description: Das Projekt "Modellierung des Wasserwaschsystems von Destillationssystemen in katalytischen Krackanlagen" wird vom Umweltbundesamt gefördert und von Universität Kaiserslautern, Lehrstuhl für Technische Thermodynamik durchgeführt. The main goal of the present project was to provide a computer program for modelling of water washing systems of catalytic cracker overhead systems. A thermodynamic model was to be developed to describe phase equilibria in the interesting systems. A temperature range from about 25 to 120 degree C, and pressures up to 2 MPa were to be covered. The proper design of an FCC (fluid catalytic cracker) main fractionating column requires the knowledge of the solubility of hydrocarbons (e.g. methane, ethane, propane, butane), as well as weak electrolytes (e.g. gases like ammonia, hydrogen sulfide, carbon dioxide, hydrogen cyanide or weak acids like thiocyanic acid, acetic acid, formic acid) and strong electrolytes (e.g. hydrogen chloride) in two liquid phases (water and an organic solvent, which was assumed to be n-hexane). The work presented here is based on former experimental and theoretical work carried out at the Lehrstuhl fuer Technische Thermodynamik. For subsystems not considered before, a literature search on the solubility of the single gases as well as on the simultaneous solubility of ammonia and a sour gas in every single solvent was carried out. The model developed is able to predict vapor-liquid-liquid-equilibria in the multi-component system only in a lmited concentration range.
