Dry HCl Gas Generation Plants

ATR Glass Process Systems offers Dry HCl Gas Generation Plants. The plant has been designed as a continuous process to produce dry HCl gas by the process of distillation of 30% hydrochloric acid solution along with a co-current stream of calcium chloride solution. The calcium chloride breaks the azeotrope formed between HCl and water and as a result almost all the HCI available in the released as gas. The moisture content in the product HCl gas is less than 0.001%. The bottom product from the column (dilute calcium chloride solution) is concentrated in the evaporator (E-4) and recycled to the distillation column. The system selected is very stable. Once all the operating conditions are stabilized and maintained; rate of generation of HCl gas depends only upon rate of hydrochloric acid (30%) feed. The system turndown ratio is high. All the wetted parts of the system are fabricated from corrosion resistant materials (glass and PTFE).
