Please ask the original poster whether the hydrochloric acid in question is a reprocessing acid or a synthetic acid. If it is a synthetic acid, full distillation can be used; after cooling and water removal, the water content is reduced to below 100 ppm, making the wastewater easier to treat (although it requires a significant amount of steam). 2. If it is an by-product acid, semi-desorption is employed; after cooling and water removal, the HCL contains less than 100 ppm of water. The concentration of the dilute acid after desorption is around 21%. In the absence of a source of HCl gas, it is difficult to handle this dilute acid (as it requires relatively little steam).
As for the by-product hydrochloric acid, economic factors, corrosion issues, safety concerns, and other aspects need to be taken into account
Anhydrous hydrogen chloride can be produced through deep purification using hydrochloric acid; the energy requirements for this process require expertise to determine
