Publication number: 20240018020Abstract: The present invention provides a method for purifying a liquid to be treated, the method being capable of reducing the content of metal impurities in the liquid to be treated containing tetraalkylammonium ions, and further, being capable of suppressing cracking of the resin even when a strongly acidic cation exchange resin is used. The method includes: an impurity removal step of passing a liquid to be treated that contains tetraalkylammonium ions and metal impurities through a container filled with a cation exchange resin of a hydrogen ion form or a tetraalkylammonium ion form to reduce the content of the metal impurities in the liquid to be treated, wherein the degree of cross-linking of the cation exchange resin is from 16% to 24%.Type: ApplicationFiled: September 27, 2021Publication date: January 18, 2024Applicant: ORGANO CORPORATIONInventors: Noriko TAKADA, Kaoru NUKUI, Haruo YOKOTA

Patent number: 11559764Abstract: In one embodiment, a carbon dioxide capturing system includes an absorber to absorb CO2 from first gas into lean liquid, and produce rich liquid that is the lean liquid absorbing the CO2 and second gas that is the first gas removing the CO2, and a regenerator to separate third gas including the CO2 from the rich liquid flowing from the absorber, and provide the lean liquid and the third gas. The system further includes a flowmeter to measure a flow rate of the third gas, a liquid level gauge to measure a liquid level of the lean liquid and/or the rich liquid, and a controller to regulate a quantity of heat energy supplied to the regenerator based on the flow rate of the third gas, and regulate a total amount of the lean liquid and the rich liquid in the system based on the liquid level.Type: GrantFiled: July 27, 2020Date of Patent: January 24, 2023Assignees: KABUSHIKI KAISHA TOSHIBA, TOSHIBA ENERGY SYSTEMS & SOLUTIONS CORPORATIONInventors: Mitsuru Udatsu, Noriko Takada, Yusuke Handa, Hideo Kitamura

Publication number: 20220387987Abstract: A method for purifying a non-aqueous solvent includes: pretreating by passing a non-aqueous solvent for dehydration treatment through a packed bed of an ion exchange resin that is not yet subjected to dehydration treatment, to remove water in the ion exchange resin; and purifying by passing a non-aqueous solvent to be purified through the packed bed of the ion exchange resin from which water is removed during the pretreating, to purify the non-aqueous solvent to be purified, in which the harmonic-mean particle size of the ion exchange resin is 0.20 to 0.50 mm. According to the present application, a method for purifying a non-aqueous solvent can be provided, the method includes pretreating by removing water in a water-containing ion exchange resin by passing therethrough a non-aqueous solvent for dehydration treatment, in which the amount of the non-aqueous solvent for dehydration treatment used during the pretreating is small.Type: ApplicationFiled: November 24, 2020Publication date: December 8, 2022Applicant: ORGANO CORPORATIONInventors: Yui SHIOYA, Miwa ITO, Noriko TAKADA, Kaoru NUKUI
