Moon-TECH Environmental Technology Co., Ltd., in collaboration with Sinopec Qingdao Refining & Chemical Co., Ltd., Xi’an Jiaotong University, and others, has passed a scientific and technological achievement evaluation for its “Indirect Working Fluid Heat Pump Distillation System for the Petrochemical Sector.” The evaluation was organized by the China Energy Conservation Association in Beijing.
The assessment committee included experts from Xi’an Jiaotong University, Beijing University of Technology, Sinopec’s Science & Technology Department, and other institutions. Chaired by Professor He Yaling of Xi’an Jiaotong University, the committee reviewed technical documents, listened to the project presentation, and held detailed discussions.
According to the committee’s conclusion, the project involves high technical difficulty and demonstrates strong innovation, achieving a level comparable to international standards. Specific technologies—such as the R152a heat pump system and a high-efficiency oil-injected twin-screw compressor—were recognized as internationally leading. The system has already been applied in industrial settings with positive user feedback and was officially approved as a scientific and technological achievement.
The system is in operation at a refining enterprise, where it recovers condensation latent heat from the top of a distillation tower and, through the heat pump cycle, converts it into high-grade thermal energy for the reboiler. This retrofit enables annual savings of over 40 million RMB (approx. USD 5.5 million) and reduces CO₂ emissions by 79,530 tons.
Moon-TECH stated it will continue promoting energy-saving innovation and support China’s green, low-carbon development goals through collaboration with industry organizations and the implementation of advanced technologies.
