gypsum and sulfuric acid in the manufacture of white cement

Technology improvement of production of sulfuric acid

The improved drying and calcination process with a vertical drying dehydration device was proposed for the production of sulfuric acid integrated with cement from phospho­gypsum, aiming at increasing the SO 2 concentration in the flue gas and reducing the ­system heat consumption. The improved process has been applied in the design of a practical project in Ningxia (China) and is expected to
