Latest Patents

One of Hirano's latest patents involves a sodium-based dechlorinating agent and waste treatment equipment. This innovative agent is added to flue gas to remove hydrogen chloride as a residue of dechlorination. The removed residue is then dissolved in water, allowing for the separation of water-insoluble constituents from the resulting aqueous solution. After adjusting the pH of the remaining solution, harmful substances such as mercury and dioxins are effectively removed and discharged. The sodium-based dechlorinating agent is mixed with a hydrophilic anti-caking agent, which helps prevent pressure drops and leakage in the dust collector's filter cloth. The mean particle diameter of sodium hydrogencarbonate is carefully controlled, and the hydrophilic anti-caking agent comprises silica, ensuring optimal performance in waste treatment processes.
