On April 30, 2010, at Henan Xinlianxin Gas Co., Ltd., a subsidiary of Henan Xinlianxin Chemical Group, a newly constructed 50kt/a liquid carbon dioxide plant began producing liquid carbon dioxide with a purity of 99.99%. All other specifications meet the requirements of the new national standard GB10621-2006, as well as the standards set by Coca-Cola and PepsiCo. This marks the successful, first-time commissioning of yet another complete CO₂ production unit designed and commissioned by our company, representing a major step forward on the path toward energy conservation, emissions reduction, and a circular economy!

  Henan Xinlianxin Gas Co., Ltd. is a national million-ton fertilizer production base and a large-scale chemical enterprise with an annual production capacity of 1.25 million tons of urea, 600,000 tons of compound fertilizer, and 200,000 tons of methanol. Xinlianxin was the first in its industry to obtain ISO 9001:2000 and ISO 14001:2004 certifications and has been recognized as an outstanding environmental protection enterprise by the State Environmental Protection Administration and the China Nitrogen Fertilizer Industry Association. Since the fertilizer production process generates large amounts of surplus carbon dioxide gas, releasing this CO₂ into the atmosphere would cause severe environmental damage. In response to the national call for the Scientific Outlook on Development, energy conservation, emissions reduction, and a circular economy, Xinlianxin Gas Company decided to utilize the CO₂ waste gas emitted from the PSA decarbonization unit of the synthetic ammonia system to produce food-grade liquid CO₂ and related downstream products. This approach not only achieves the environmental goal of reducing emissions but also generates economic benefits for the enterprise. After nearly a year of careful comparison of the reliability of various domestic food-grade liquid carbon dioxide production technologies, Xinlianxin Gas Company ultimately decided to adopt the new food-grade liquid carbon dioxide production technology and patented equipment developed by Hangzhou Kuai Kai High-Efficiency Energy-Saving New Technology Co., Ltd., which meets international quality standards. The company constructed a 30kt/a production facility capable of simultaneously producing both industrial-grade and food-grade liquid carbon dioxide products, with the flexibility to adjust the production ratio of each product according to market demand. Since the plant’s official commissioning, under the advanced management philosophy of Xinlianxin Group and the gas plant, the facility has operated smoothly, with production capacity, process performance, product quality, and energy consumption metrics all exceeding design specifications.

  The application of our company’s international standard food-grade liquid carbon dioxide production technology at Henan Xinlianxin Group Gas Company has proven ideal. The entire plant offers advantages such as low investment, high product quality, stable production, and low energy consumption. It represents the best choice for fertilizer manufacturers seeking to develop a circular economy, conserve energy, reduce emissions, lower production costs, fulfill social responsibilities, and enhance overall corporate competitiveness. It also aligns with relevant national policies and responds to the national call for energy conservation and emission reduction. Our company’s high-quality services and unique patented technology will undoubtedly play a more prominent role in China’s future efforts to conserve energy and reduce emissions. While providing superior services to more chemical enterprises, we will also better serve the public and protect the environment.
