Latest Patents
Aspengren holds a patent for a process titled "Process for preparing calcium thiosulfate solution." This patent describes an efficient method to produce calcium thiosulfate (CaSO) from lime, sulfur, and oxygen. By selecting appropriate process conditions such as mole ratios of lime to sulfur, temperature, and pressure of the reaction process, as well as oxidation conditions, 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 then be acidified and treated with a flocculent, allowing the solids to agglomerate into a floc that filters easily. The resulting calcium thiosulfate is a clear liquid with concentrations achievable up to 29%.
