Latest Patents

Among his latest inventions is a groundbreaking method for adiabatic cooling type crystallization of organic compounds. This innovative process involves several key steps: it begins with the adiabatic cooling and evaporation of a coolant in a crystallizer for a mixed solution of a target organic compound. Following this, crystal slurry produced from the operation is extracted from the crystallizer. The evaporated vapor is then pressurized by a compressor to exceed the operational pressure within the crystallizer before being introduced to an absorption condenser. In this condenser, the mixture solution of organic compound and pressurized evaporated vapor contact each other, allowing for efficient cooling and condensation. Finally, the clarified liquid resulting from the purification process is reintroduced to at least one of the crystallizer and absorption condenser, effectively enhancing the overall process efficiency and lowering operational costs.
