Osaka Gas Liquide has established a fully-owned company to produce and sell liquid carbon dioxide (LCO2) and dry ice in Nagaoka City, Niigata. The plant will be the company’s first industrial gas plant outside the Kansai district.

Carbon dioxide is a by-product gas generated in oil refinery facilities or from an ammonia producing process. In recent years the supply of crude CO2 has ran short over the country due to the down-scaling of producer’s facilities.

Mitsubishi Gas Chemical closed Niigata Plant in 2015 which had been producing ammonia in Tohoku/Hokuriku Districts. Since then the situation of no CO2 gas source has been enduring.

Nagaoka Tansan of the new company is the second CO2 gas plant following Kinki Tansan, which was invested by Osaka Gas Liquid, Nippon Ekitan and others. 

The production capacity is 4,500t tonnes per month, but the specifications of other capacities (LCO2gas purification and storage and the output of dry ice) are still now under consideration.

The construction period has been set from March 2019 to March 2021, with operation planned to start from April 2021.

The new construction site is adjacent to INPEX Corporation Nagaoka Oil Mine, a petroleum and natural gas developing company. The mine takes a share of 40% of the domestic natural gas output.

The by-product CO2 gas supplied is said to have a purity of 97- 98%.

It is planned that after the scheduled start of the operation about 20 employees will be engaged in the plant management, and general affairs for the operation, half of the employees are hoped to be recruited locally.

“… across the company the supply of CO2 does not cover the demand at all. We wish to build more plants if the chance arises. We do want to contribute to a stable supply system in the region through the supply of our product to all the other CO2 manufactures,” said a member of staff in charge of the company.
