Publication number: 20240001287Abstract: Provided is a regeneration device for heating a treatment liquid in a phase-separated state due to absorption of an acidic compound to release the acidic compound and regenerate the treatment liquid. The regeneration device includes a container for storing the treatment liquid, and a first wall that partitions a space in the container into a first space and a second space. The first space includes: a heating region that receives the treatment liquid supplied from an outside of the container and in which a heating unit for heating the treatment liquid is disposed; and a static region that receives the treatment liquid from the heating region, the treatment liquid having released the acidic compound by being heated by the heating unit. The second space allows the treatment liquid having released the acidic compound to be discharged. The first wall is provided with an opening through which the treatment liquid in the static region flows into the second space.Type: ApplicationFiled: September 2, 2021Publication date: January 4, 2024Applicant: KABUSHIKI KAISHA KOBE SEIKO SHO (KOBE STEEL, LTD.)Inventors: Norihide MAEDA, Akira KISHIMOTO, Takuo SHIGEHISA, Ken NAKANISHI, Kunihiko SHIMIZU
