Sulphuric and hydrochloric acid recovery system is used for the steel, wire and galvanizing industries. It deals with the ever-increasing environmental and legislative challenges facing companies working on metal finishing and cleaning processes. A crystallization process eliminates waste from operations using sulphuric acid. This process cools the spent pickling liquor and produces a saleable ferrous sulphate crystal. The advantage of this system includes the re-use of highly concentrated recovered acid in the pickling process and Stabilized and reduced time of pickling operations.
