The company integrates R&D, technological upgrades, project consulting and evaluation, engineering design, equipment manufacturing, turnkey equipment supply, commissioning, EPC contracting, and technical optimization and upgrading services.
With over two decades of experience in methanol synthesis, ammonia synthesis, methanol distillation, and the production of “food-grade carbon dioxide meeting international quality standards,” the company boasts a team of professors and industry experts with extensive experience in methanol synthesis, ammonia synthesis, industrial CO₂ tail gas treatment and recovery, and specialty gas production. Backed by strong technical capabilities, the company is committed to independent innovation and continuously develops new technologies, products, and equipment. The company has obtained more than 10 national invention patents and over 30 utility model patents. Its methanol synthesis reactor has been awarded the Second Prize for Scientific and Technological Progress at the ministerial level and the Zhejiang Provincial Excellent Science and Technology Product Award. In the field of CO₂ preparation technology, the company has undertaken two innovation fund projects from the Ministry of Science and Technology and has received more than ten provincial, ministerial, and municipal honors. The “International Quality Standard Food-Grade CO₂ Production Technology” has passed provincial-level appraisal, with the conclusion that it is “domestically leading and internationally advanced.”
The company operates a Hangzhou municipal-level high-tech R&D center and has established close R&D partnerships with universities and research institutions such as Zhejiang University, Southeast University, Zhejiang University of Technology, the New Energy Technology Research Institute Co., Ltd. of the National Energy Group, the Chinese Academy of Sciences, the Sinopec South China Research Institute of Petrochemical Technology, and Dalian Ruike Technology Co., Ltd. The company possesses the necessary conditions and capabilities for process development, process optimization, the development and manufacturing of specialized patented equipment, and the research and development of reactors and catalysts required for pilot-scale testing and industrialization. It is equipped with comprehensive analytical and testing capabilities and possesses strong capabilities for the commercialization of R&D outcomes as well as extensive engineering experience. The company has achieved phased results in projects jointly developed with Zhejiang University of Technology, including the optimization of production processes for high-purity dimethyl carbonate (DMC).
The Company’s proprietary “New Energy Methanol Synthesis Loop” process package, various methanol synthesis reactors, and proprietary methanol catalysts (for biomass and electrolytic hydrogen-based methanol production) are suitable for a wide range of new processes and equipment for producing methanol from biomass, as well as green methanol from CO₂ and electrolytic hydrogen. The company advances the R&D, engineering design, and industrialization of green methanol in accordance with EU standards, developing a variety of reactors to accommodate mainstream process routes such as biomass gasification for green methanol production and the use of green electricity to electrolyze hydrogen combined with CO₂ for green methanol production. The methanol synthesis reactors developed feature small temperature differentials, high conversion rates, and low equipment costs. The company has undertaken more than 100 methanol synthesis and ammonia synthesis projects.
The company’s proprietary technologies—including shallow-temperature distillation, multi-stage distillation, multi-stage liquefaction, novel catalytic oxidation (dehydrocarbonization and purification) processes, next-generation chemical absorption carbon capture and purification, precision washing and adsorption, and diversified skid-mounted and cold box units—are adaptable to diverse geographical environments and feed gas conditions. Multi-stage distillation and multi-stage liquefaction are suitable for low-concentration CO₂ feedstocks, while the novel catalytic oxidation dehydrocarbonization purification technology (dehydrocarbonization purification) is the most effective method for producing food-grade CO₂ from hydrocarbon-containing CO₂ streams. Through the optimization and improvement of this process flow and key equipment, the patented unit offers advantages such as low investment costs, a small footprint, and thorough purification. It ensures consistent compliance with or exceeding the “High-Purity Carbon Dioxide” standard (GB/T 23938-2021), while the vented tail gas emissions meet the “Petrochemical Industry Pollutant Emission Standard” (GB 31571-2015). Concurrently, our company is engaged in the design and construction of dry ice production facilities and has developed a new low-energy-consumption technology for the recovery of dry ice off-gas, significantly reducing dry ice production costs while enhancing the profitability and market competitiveness of dry ice manufacturers. Furthermore, we have developed multiple new technologies related to carbon neutrality, including comprehensive utilization of carbon dioxide and downstream products (such as hydrogenation of carbon dioxide to produce new energy sources).
Food-grade carbon dioxide produced using our patents, proprietary technologies, and proprietary catalysts meets the standards of the International Society of Beverage Technology (ISBT), the national standard (GB 1886.228-2016), and the specifications of “Coca-Cola” and “PepsiCo,” as well as the high-purity carbon dioxide standard (GB/T 23938-2021). with CO₂ purity reaching 99.995% or higher, and even 99.9999% (electronics grade). Many of our customers have been designated as qualified suppliers by beverage and beer companies such as “Coca-Cola” and “PepsiCo.”
Our company operates more than 300 units designed to produce various grades of standard carbon dioxide from different feed gases. We possess extensive experience in engineering design, equipment manufacturing, and installation and commissioning. Many of our units have been exported to countries and regions including the United States, Russia, Vietnam, India, Indonesia, Tajikistan, Guinea, Cameroon, and Sierra Leone. The largest single CO₂ unit has reached a capacity of 600,000 metric tons per year. We have also successfully developed skid-mounted units for producing 50–1,000 kg/h of electronic-grade ultra-high-purity CO₂, as well as a new process for CO₂ capture via oxygen-enriched combustion and associated compression and purification units. This new process utilizes alcohol tail gas to truly meet food-grade quality standards. The pilot-scale facility for the next-generation chemical absorption CO₂ capture and purification technology, jointly developed by our company and Zhejiang University, has completed multiple experimental runs. The data obtained has laid the foundation for the technical assurance of the 500,000-ton CO₂ capture industrialization project by the State Energy Group—the first such project in China under the Ministry of Science and Technology’s R&D program. This technology is suitable for low-concentration CO₂ gas capture and purification in CCUS and CCS applications across coal-fired power plants, gas combustion, steel, and cement industries, such as exhaust gases emitted from power plant boilers, steel smelting (blast furnace gas tail gas), lime kilns, and cement plants. To support and advance the nation’s goals of carbon peaking and carbon neutrality, the company has established the “Zhejiang University of Technology Carbon Neutrality Technology Training Center” in collaboration with Zhejiang University of Technology. The center provides multiple pilot-scale carbon neutrality technology facilities and serves as the sole partner for Zhejiang University of Technology’s carbon neutrality technology training and service market, aiming to contribute to the cultivation of talent and technological advancement in carbon neutrality across the country. Additionally, the company has constructed a new chemical absorption carbon capture facility for Southeast University, which is currently the largest pilot-scale facility in China.
The company possesses design capabilities for Class I, II, and III pressure vessels, cold boxes, and skid-mounted equipment, and has established two manufacturing bases and an experimental pilot plant (Nantong Kuai Kai Energy Conservation and Environmental Protection Technology Co., Ltd. and Hangzhou Lizhilian New Energy Equipment Co., Ltd.).
