Yangmei Hengtong MTO project achieves highest level of olefin separation yield

Thread Content

Recently, Huisheng Engineering announced that the 300,000 tons per year methanol-to-olefins (MTO) project of Shandong Yangmei Hengtong Chemical Co., Ltd. (hereinafter referred to as “Yangmei Hengtong”), which is under its EPC general contracting and utilizes olefin separation technology based on its own intellectual property, has passed the performance assessments and inspections for the olefin separation unit organized by the project owner after ten months of stable operation, achieving excellent results. The recovery rates of ethylene and propylene products have reached the highest levels in the global industry to date. During the 72-hour performance test period, the olefin separation unit operated at full capacity steadily, and the quality of the produced ethylene and propylene met the specifications for polymer-grade products. While maintaining the required overall energy consumption levels, the recovery rate for ethylene products reached 99.89%, and that for propylene products reached 99.96%. These figures exceed the performance requirements set, representing the highest recovery rates achieved to date since the industrial application of Whiting’s olefin separation technology; they also represent the highest levels in the global industry at present. Li Yansheng, a leading scientist at Huisheng Engineering, said: “During the 13th Five-Year Plan period, modern coal chemical industry remains an inevitable path for China’s energy substitution development strategy.” Improving economic efficiency and environmental sustainability through technological innovation is particularly important for the sustainable development of MTO technology in the current energy landscape. Huisheng Engineering has been committed to optimizing technologies for energy savings and reduced consumption, as well as improving product yields. ”In June 2015, this olefin separation technology passed the scientific and technical achievement evaluation organized by the China Petroleum and Chemical Industry Federation; compared with other olefin separation technologies at home and abroad, the optimized UOP methanol-to-olefins separation technology reached an internationally leading level. The Yangmei Hengtong MTO project is the third project in which Huisheng Engineering’s olefin separation technology has been successfully applied on an industrial scale, and it also makes use of UOP’s advanced MTO reaction technology. The successful delivery and operation of this project once again demonstrate the low energy consumption and high yield characteristics of Huisheng’s olefin separation technology. It also highlights Huisheng Engineering’s integrated capabilities in MTO projects, covering technology, front-end design, engineering design, procurement, construction, and operational services.
