On November 14-15, 2022, the technical appraisal meetings for two new products, "Skid-mounted Mixed Refrigerant Oil Injection Screw Compressor Unit for Dispersed Natural Gas Liquefaction" and "Multi-temperature Zone Condensing Cascade Recovery Unit for Volatile Organic Compounds," were successfully held. These products were jointly developed by Moon Environmental Technology Co., Ltd., Xi'an Jiaotong University, the Institute of Physics and Chemistry of the Chinese Academy of Sciences, and Shandong MOON-Haizhuo Hydrogen Energy Technology Research Institute Co., Ltd.
The appraisal was organized by the China General Machinery Industry Association (CGMA), with President Huang Li presiding. The expert panel was chaired by Sui Yongbin, former Chief Engineer of the China Machinery Industry Federation, and included experts from organizations such as China Machinery Federation, Sinopec Guangzhou Engineering Company, Sinopec Engineering Construction Company, Harbin Engineering University, Yantai Industrial Design Research Institute, Sichuan Air Separation, Qingdao Huashi Jie Environmental Protection, and Beijing Hongke Qing Energy. Professor Xing Ziwen from Xi'an Jiaotong University and Researcher Gong Maoqiong from the Institute of Physics and Chemistry, CAS, participated as members of the project team.
The expert panel listened to the development summary reports, reviewed relevant technical documents, witnessed the physical products and some performance tests, and after inquiries and discussions, both new products passed the appraisal. The appraisal committee concluded that:
The skid-mounted mixed refrigerant oil injection screw compressor unit developed for dispersed natural gas liquefaction exhibits good sealing performance and high efficiency. It is easy to transport, install, and quickly relocate the operation site. Its overall performance reaches an advanced international level, with adiabatic efficiency being world-leading. The product has been mass-produced and achieved good economic and social benefits. It is recommended to further perfect the product series and expand its application scope.
The developed device for the multi-temperature zone condensing cascade recovery of volatile organic compounds features a parallel dual-channel organic compound auto-defrost system and intelligent control technology, enabling stable switching between condensation and defrosting, ensuring continuous and efficient operation of the equipment. Through gas-liquid biphasic organic compound cold energy recovery technology, the system achieves tiered utilization of energy, avoiding additional heating energy consumption and improving system energy efficiency. The technical indicators of the product have reached an advanced international level, and it is recommended to further expand the scope of application of the achievements.
For many years, MOON-TECH has been focusing on industry technology research, leading technological transformations and upgrades in the industry, and has independently developed multiple core products and patented technologies. Following MOON-TECH's "Oil Injection Screw Hydrogen Transport Compressor" and "High-Pressure Hydrogenation Compressor," which completed the independent tackling of core equipment in the hydrogen field and industrial layout, new products in the "clean energy" and "energy-saving and environmental protection" fields have been launched.
The development of the "Skid-mounted Mixed Refrigerant Oil Injection Screw Compressor Unit" reduces the energy consumption and investment costs of natural gas liquefaction systems, achieves efficient recovery and utilization of unconventional natural gas, effectively reducing unordered greenhouse gas emissions, and protecting the ecological environment. The development of the "Multi-temperature Zone Condensing Cascade Recovery Unit for Volatile Organic Compounds" achieves efficient and tiered recovery and utilization of various VOCs, effectively reducing the harm of VOCs to human health and the atmospheric environment, and has been successfully applied in several large-scale projects with huge market potential.
Looking to the future, MOON-TECH will continue to practice the green development philosophy, play the leading role of enterprise innovation, continuously seek and breakthrough in independent research and development and innovation, and strive to write a new chapter in China's low-carbon development with high-quality environmental products and services.
