Title: The Innovative Contributions of Isao Kikuchi
Introduction
Isao Kikuchi is a notable inventor based in Ohmuta, Japan. He has made significant contributions to the field of chemical engineering, particularly in processes involving chlorine. With a total of 4 patents to his name, Kikuchi's work has had a considerable impact on industrial processes.
Latest Patents
Kikuchi's latest patents include a concentration process of gaseous chlorine and an industrial process for the separation and recovery of chlorine. In his innovative method, a gaseous mixture containing chlorine, carbon dioxide, and non-condensable gas is compressed and cooled. This process separates the mixture into a residual gas, primarily composed of non-condensable gas, and a condensate mainly consisting of chlorine. The condensate is then fed into a stripping column to desorb carbon dioxide and a minor portion of the non-condensable gas. The stripped gas, which is primarily chlorine and carbon dioxide, can be further treated. Specifically, the stripped gas is mixed with the residual gas, and a portion of this mixed gas is fed into an absorption column. This process allows for the absorption of a major portion of the remaining chlorine, effectively lowering its content. The removal of chlorine from the gaseous mixture can be achieved by washing it with an aqueous solution or suspension containing alkali metal sulfite and/or alkaline earth metal sulfite, while maintaining the pH within a range of 1.9-6.3.
