Wison Engineering, a chemical engineering, procurement and construction management service and technology provider in China, has announced that a 300-kta methanol-to-olefin (MTO) project (the YangMei Project),undertaken by Wison Engineering for Shandong YangMei Hengtong Chemicals Company Limited (YangMei Hengtong) under an EPC contract and employing its proprietary olefin separation technology, has passed the performance test for olefin separation unit organised by the client with its excellent operation performance after 10-month steady operation. The product recovery of ethylene and propylene products has reached top standard in the industry globally.
During the 72-hour performance test, the plant maintained stable running at full capacity, with the quality of the ethylene and propylene products meeting the polymer specs. The product recovery of ethylene and propylene reached 99.89% and 99.96% respectively, higher than the guaranteed value. Meanwhile, the plant energy consumption also surpassed the guaranteed requirement. This is the highest recovery since the first commercialisation of the Company’s olefin separation technology, which is also the best achievement in the industry worldwide.
Yansheng Li, Chief Scientist of Wison Engineering says, “During the ‘13th Five-year Plan’, the development of modern coal-chemical industry is an affirmative way in performing the oil-substitution energy strategy of China. It’s crucial to enhance economic efficiency and environmental protection through technological innovation for the sustainable development of MTO in the current energy market circumstances. Wison Engineering’s been committed to optimise the technologies to reduce energy consumption and enhance product recovery.”
In June 2015, Wison Engineering’s olefin separation technology passed scientific and technological appraisal conducted by the China Petroleum and Chemical Industry Federation (CPCIF). Compared with other local or foreign technologies, Wison Engineering ‘s olefin separation technology has reached advanced international standards.
YangMei HengTong 300kta MTO project is the third operational project to adopt the Wison Engineering’s olefin separation technology since it was industrialised.
