摘要： A catalytic process for preparing chlorine from hydrogen chloride, which includes recycle of process streams with reduced accumulation of inert gases in the system is provided. The process includes a step wherein a compressed liquid stream comprising chlorine, carbon dioxide and oxygen is recycled into a column countercurrent to the ascending gas phase and feeding part of the chlorine-rich liquid phase leaving the bottom of the column back into the top of the column. Carbon dioxide present in the ascending gas stream is dissolved out of the gas stream and can later be separated from chlorine without problems by distillation.

摘要： The invention relates to a method of operating a liquid ring compressor having an impeller installed eccentrically in a compressor body, with gas being supplied to the liquid ring compressor on a suction side and gas being discharged from the liquid ring compressor on a pressure side. A liquid ring is generated in the liquid ring compressor on the inside of the compressor body by rotation of the impeller. Chambers are formed between blades of the impeller and the liquid ring and gas is drawn into these. The gas is compressed in the chambers which become smaller from the suction side to the pressure side as a result of the rotation of the eccentrically mounted impeller. The compressed gas is ejected on the pressure side. An ionic liquid is used as service liquid for generation of the liquid ring.
