Abstract:
Single-pipe filling rising film condensation and crystal desalination is a developed process to treat waste sulphuric acid. This process applies vacuum condensation and sulphuric acid refrigeration to the treatment of waste sulphuric acid. In the treatment process, H2SO4 and FeSO4 of waste sulphuric acid are reclaimed, and it has fully realized zero discharge. Single-pipe filling rising condensation and crystal desalination process has prosperous future in our country.
Key words:
