MHI completes installation of CO2 capture unit at Nippon Ekitan's Mizushima Plant

Jan 03 2018

It will capture CO2 from Mitsubishi Chemical Corporation's (MCC) Mizushima Plant, and feed it to Nippon Ekitan's new liquefied carbonic acid gas production facility.

The new unit offers a recovery capacity of 283 metric tons per day (mtpd). 

MHI licensed its CO2 capture technology to Mitsubishi Chemical Engineering Corporation, which handles engineering, procurement and construction (EPC) of the new liquefied carbonic acid gas production facilities. MHI oversaw the basic design of the CO2 capture unit and supplied its core components.

Nippon Ekitan is a group company of Taiyo Nippon Sanso Corporation, which operates a carbonic acid gas business in Japan. The company mainly purchases high-concentration carbonic acid gas from petrochemical firms, ammonia manufacturers, and other producers, liquefies and refines it, and then markets it as liquefied carbonic acid gas and dry ice.

The Taiyo Nippon Sanso Group was integrated into the Mitsubishi Chemical Holdings Corporation Group in November 2014, and works in collaboration with the group's various business enterprises. This new liquefied carbonic acid gas production facility uses an absorption solvent to separate and capture CO2 from low-concentration carbonic acid gas from Mitsubishi Chemical's Mizushima Plant, where Nippon Ekitan's Mizushima Plant is located, to produce high-quality liquefied carbonic acid gas.

The liquefied carbonic acid gas facility will help to further ensure a stable supply of carbonic acid gas from Nippon Ekitan in the Chugoku and Shikoku regions, and Kansai area. MHI received a letter of appreciation from the company for completing the installation on schedule and with zero accidents, working in tandem with the ongoing plant construction.
