In this application, chlorine gas is recovered and compressed. Chlorine gas is lethal, toxic and extremely corrosive therefore special consideration to the compressor material, seal liquid, and system configuration is required. Low pressure chlorine gas applications using high concentration sulfuric acid can be handled by a standard nodular cast iron compressor. With lower operating temperatures and sulfuric acid as a seal liquid, there is little to no risk of rust occurring in the iron, making cast iron a more cost-effective choice than Hastelloy. Conversely, high pressure applications require a compressor casing made from Austenitic Stainless Steel (316L or HC276 for certain applications), with ancillaries in the steel to cater for proper corrosion allowances. Our application specialists and engineers are experienced in the design of chlorine compressors and systems and can configure a solution to meet your process needs.
