Shandong Yisheng Gas Co., Ltd., located in Zaozhuang City, Shandong Province, specializes in the production and sale of various industrial gases. The company is utilizing waste gas from the Phoenix Energy Plant to construct a 300kt/a liquid carbon dioxide facility (producing both industrial-grade and food-grade products, with 150,000 tons per year of food-grade liquid carbon dioxide).

Our company is responsible for the engineering design of this project and provides patented, proprietary equipment and specialized dehydrocarbonation catalysts to ensure that the quality of the carbon dioxide consistently meets all specified standards. The performance metrics for both industrial-grade and food-grade products exceed the requirements of the design and contract, as well as the standards set forth in GB/T 6052-2011 “Industrial Liquid Carbon Dioxide” and GB 1886.228-2016 “National Food Safety Standard: Food Additives—Carbon Dioxide.” The project successfully commenced operations in early 2023.
