Mineral Acid Treatment

Corrosion resistant process systems to recycle, purify, concentrate or dilute highly corrosive acids

Nitric Acid Concentration Column.pngThe chemical industry produces thousands of tons of mineral waste acids diluted with water, mixed with other acids, or contaminated with other inorganic or organic components.  De Dietrich Process Systems provides clean, modern, and energy efficient plants to process mineral acids without contaminating the environment. 

Our capabilities expand across the globe, designing and engineering plants for the following processes:

Concentration

Recovery and Purification

  • Denitration and recovery of mixed acids from nitration plants
  • Recovery of hydrochloric acid
  • Cleaning of hydrochloric acid
  • Purification of spent acids from etching processes
  • High purity (electronic grade) acids: HCl, HNO3, H2SO4

HCl Treatment

  1. Absorption of Hydrogen Chloride
  2. Isothermal absorption
  3. Adiabatic absorption
