SHANGHAI, June 14, 2016 /PRNewswire/ -- Wison Engineering ("the Company"), one of the leading chemical engineering, procurement and construction management ("EPC") service and technology providers in China, announced that a 300kta 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 organized 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 commercialization of the Company's olefin separation technology, which is also the best achievement in the industry worldwide.
Yansheng Li, Chief Scientist of Wison Engineering said, "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 optimize 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 Company's olefin separation technology since it was industrialized. The project also adopted the patented methanol to olefin (MTO) and olefin cracking process (OCP) technology developed by UOP. The successful delivery and operation of the project has not only proven the features of low energy consumption and high recovery of Wison's proprietary technology but also demonstrated its integrated capabilities on R&D, PDP, FEED, engineering design, procurement, construction and operation services of MTO projects.
About Wison Engineering's Olefin Separation Technology
Wison Engineering's self-developed proprietary "pre-cutting + oil absorption" olefin separation technology integrated a pre-cut column to separate C1 and lighter components from most C2 by non-sharp distillation. The overhead of pre-cut column is sent to the oil absorber, and the absorbent absorbs C2 and heavier components to separate C1 from C2 completely. The absorbent at the exit of the oil absorber bottom is sent to the top of pre-cut column for regeneration. By adopting a proprietary "Falling-film heat exchanger", the oil absorber condenser can transfer heat and mass simultaneously. So that ethylene recovery can be improved while the energy consumption is reduced.
