MUMBAI, India, Sept. 26 -- Intellectual Property India has published a patent application (202544020289 A) filed by Kabushiki Kaisha Toshiba; and Toshiba Infrastructure Systems & Solutions Corporation, Tokyo, on March 6, for 'water treatment system, water treatment method, and amine solution.'
Inventor(s) include Yoshihiko Nakano; Akiko Suzuki; and Reiko Yoshimura.
The application for the patent was published on Sept. 26, under issue no. 39/2025.
According to the abstract released by the Intellectual Property India: "A water treatment system according to an embodiment includes an element introducing water to be treated into a first container, an element introducing an amine solution into the first container to obtain a first mixture, and an element separating a supernatant phase and a concentrated phase of a second mixture in which the first mixture is phase-separated. The amine solution includes one or more amine compounds represented by a chemical formula (1) or/and a chemical formula (2). R1 of the chemical formula (1) is a straight-chain alkyl chain having 2 or more and 6 or less carbon atoms, a branched alkyl chain having 4 or more and 6 or less carbon atoms, a cyclic alkyl chain having 5 or 6 carbon atoms, an ether chain having 2 or more and 6 or less carbon atoms, or an aminoalkyl chain having 2 or more and 9 or less carbon atoms. R2 of the chemical formula (1) is a hydrocarbon group having 1 or more and 6 or less carbon atoms. R3 of the chemical formula (1) is a hydrocarbon group having 1 or more and 6 or less carbon atoms. In the chemical formula (1), the ratio of [number of carbon atoms in the molecule] / [number of nitrogen atoms in the molecule] is 4.0 or more and 7.0 or less. R4 of the chemical formula (2) is a straight-chain alkyl chain having 2 or more and 6 or less carbon atoms, a branched alkyl chain having 4 or more and 6 or less carbon atoms, a cyclic alkyl chain having 5 or 6 carbon atoms, an ether chain having 2 or more and 6 or less carbon atoms, or an aminoalkyl chain having 2 or more and 9 or less carbon atoms. R5 of the chemical formula (2) is a hydrocarbon group having 1 or more and 6 or less carbon atoms. R6 of the chemical formula (2) is a hydrocarbon group having 1 or more and 6 or less carbon atoms. R7 of the chemical formula (2) is a hydrocarbon group having 1 or more and 6 or less carbon atoms. In the chemical formula (2), the ratio of [number of carbon atoms in the molecule] / [number of nitrogen atoms in the molecule] is 4.0 or more and 7.0 or less."
