In response to the call for energy conservation, emissions reduction, and the development of a circular economy, Anhui Liuguo Chemical Co., Ltd. began researching food-grade carbon dioxide recovery technologies and downstream products in January 2012. After nearly a year of research and comparative evaluations of design firms, the company signed a contract with our firm in January 2013 for a project involving a facility with an annual production capacity of 200,000 metric tons of food-grade carbon dioxide and its downstream products.

  Based on the composition of the company’s CO₂ feed gas, our company finalized the design plan and carried out engineering design, supply, and commissioning in accordance with the construction drawings. Through the joint efforts and cooperation of our technical staff, the facility achieved successful first-time startup, with all production process indicators exceeding design requirements. According to on-site analytical instrument testing, product purity is consistently maintained at 99.99% or higher, with total hydrocarbons ≤10 ppm. All results meet the quality requirements for food-grade carbon dioxide (GB10621-2006).

  Anhui Liuguo Chemical Co., Ltd. is a key enterprise in the national strategy for the development of large-scale phosphate compound fertilizer production. The company is primarily engaged in the mining and beneficiation of phosphate ore, as well as the production and sales of phosphate compound fertilizers, fine phosphate chemicals, synthetic ammonia, and methanol.

  Our company’s mature technology and professional services have been highly recognized by the client. The application of our patented technology and equipment for the production of food-grade liquid carbon dioxide has proven highly effective, featuring low investment costs, low energy consumption, high-quality output, a high degree of automation, and stable production.
