He has made significant contributions to the field of chemical engineering, particularly in the production of calcium thiosulfate. His innovative approach has led to the development of a patented process that enhances the efficiency of this chemical production.
Latest Patents
Hajjatie holds a patent for a "Process for preparing calcium thiosulfate solution." This patent describes an efficient method to produce calcium thiosulfate (CaSO) from lime, sulfur, and oxygen. By carefully selecting process conditions such as mole ratios of lime to sulfur, temperature, and pressure, he has managed to reduce the concentration of byproducts in the resulting suspension to about 2% by weight or less. The process addresses the challenge of filtering the solid particulate dispersion, which can form a slimy solid suspension if not treated properly. The suspension can be acidified and treated with a flocculent, allowing for easier filtration and resulting in a clear liquid calcium thiosulfate with concentrations achievable up to 29%.
