Latest Patents

Hasebe holds a patent for a process and apparatus for purifying elemental sulfur. This invention involves a cake containing sulfur and other materials in a base solvent, which is purified to obtain elemental sulfur. The method employs preferential solubilization of the sulfur using a selected solvent that is immiscible with the base solvent at an elevated temperature, which is less than that required to produce a phase change. After the base and selected solvents are separated, the temperature of the sulfur solvent is lowered to recrystallize elemental sulfur. This innovative process enhances the efficiency of sulfur purification.
