Abstract
A process for drying and compressing wet chlorine gas with concentrated sulfuric acid in which the drying and compressing are accomplished utilizing alternating mechanical compressors comprising a liquid ring compressor and a second compressor. The process improves the efficiency of drying and liquifying Cl.sub.2 while eliminating the cost for drying towers.
Claims11
A method of drying and compressing wet chlorine gas which comprises:
- passing the chlorine gas to be dried and compressed into at least one compression stage comprising a liquid ring compressor using sulfuric acid as the liquid medium and a second mechanical compressor.
A process for drying and compressing wet chlorine gas comprising at least one drying and compression stage wherein the gas is dried and compressed using sulfuric acid as the drying liquid wherein the process comprises
- (a) introduced the wet gas into a liquid ring compressor containing sulfuric acid, for partially drying the wet chlorine, thereafter;
- (b) separating the dried chlorine leaving the liquid ring compressor from entrained sulfuric acid in a separator;
- (c) introducing the chlorine into a second mechanical compressor where it is compressed.
