  The project was approved in July 2007 and was completed on schedule after two years of intensive research and development. During the project’s implementation period, invention patents were obtained for the dehydrocarbonization purification process and the refining tower, while a utility model patent was granted for the shallow-low-temperature composite purification tower. The core equipment—the “Food-Grade CO₂ Dehydrocarbonization Tower and Shallow-Temperature Combined Purification Tower”—was approved by the China Petroleum and Chemical Engineering Design Association as a designated product for use in chemical product construction standards. The application scope of this technology has expanded from a single source of waste gas from ammonia synthesis plants to include flue gas from coal-fired power plants, waste gas from ethanol plants, waste gas from petrochemical production units, CO₂ from gas fields, and waste gas from hydrogen peroxide plants. A series of process optimization solutions have been developed for different gas sources. In particular, the technology for producing food-grade carbon dioxide from flue gas in coal-fired power plants was successfully applied for the first time in China, pioneering the recovery of waste gas from domestic coal-fired power plants.

  After listening to the company’s deputy general manager’s introduction to the company’s profile and the project’s implementation status, the attending experts conducted a thorough review, inquiry, and evaluation of the project’s execution via on-site assessment, in accordance with the acceptance guidelines for the Technology Innovation Fund for Science and Technology-Based Small and Medium-Sized Enterprises and the indicators specified in the project contract. Following discussion by the expert panel, it was unanimously agreed that our company had achieved excellent results in meeting all indicators during the project execution period (with the expert project score reaching 108 points), thereby meeting the standards for successful acceptance.
