Wison Engineering Achieved 8th Project in Commercialization of Proprietary Olefin Separation Technology

Move Underscores MTO Project Management Capability

SHANG HAI, 12 November 2014 – Wison Engineering Services Co. Ltd. (“Wison Engineering” or the “Company”, SEHK stock code: 2236, together with its subsidiaries, the “Group”), one of the leading chemical engineering, procurement and construction management (“EPC”) service providers in China, today announced that its wholly-owned subsidiary, Wison Engineering Ltd., continued to make headway in proprietary technology transfer in methanol-to-olefins (MTO) separation technology and strengthen its EPC services in MTO unit, since its first successful commercialization of its patented technology in September 2013. At present, eight MTO projects in China, which are either under construction or completed, employ Wison Engineering’s proprietary MTO separation technology. These include the iconic PuCheng Clean Energy Chemical Co., Ltd.’s 700kta polyethylene production plant, and 680kta new coal-based materials project with MTO unit for Shenhua Coal to Liquid and Chemical Co., Ltd. . 

A few days earlier, Wison Engineering entered into an olefin separation technology licensing and engineering design contract for basic design and detailed design with Liaocheng Meiwu New Materials Tech.Corp. for a 300kta MTO unit of the oxo raw material line optimization project.
 

In addition, Wison Engineering was recently awarded to an olefin separation technology licensing agreement and an engineering, procurement and construction(EPC) contract by Shandong Better Clean Energy Co. Ltd. for the 300kta MTO unit. Upon the start-up, the plant will become another project employing Wison Engineering and UOP’s leading MTO technology, as well as being designed and managed by Wison Engineering following Wison Clean Energy ‘s MTO plant in Nanjing. The delivery of this project is expected to be on April 30, 2016.
 

A number of projects designed by Wison Engineering and adopting its proprietary olefin separation technology are progressing smoothly. Shandong Dongrun Clean Energy Co., Ltd.’s 600 kta MTO plant and ancillary project has commenced phase I design work for its 300 kta MTO unit, olefin tank and all auxiliary facilities underway. The detailed design is expected to be completed on 31 August 2015. Other projects include relevant technology licensing and design work of Shandong Yangmei Hengtong Chemicals Company Ltd.’s 300kta MTO plant, PuCheng Clean Energy Chemical Co., Ltd.’s 700kta coal-to-olefins project and Shenhua Coal to Liquid and Chemical Co., Ltd.’s 680kta new coal-based materials project with MTO unit have been completed.
 

The first commercialized project – Wison Clean Energys 300 kta MTO plant featuring Wison Engineering’s olefin separation technology and UOP’s Menthol-to-Olefin (MTO) technology has been operating smoothly since the successful launch in Nanjing in September 2013. The plant consumes only 2.6 tons of methanol per ton of olefins, while the conversion ratio of C4 + olefins to propylene and ethylene is 4: 1 and the product recovery ratio is as high as 99.6%, demonstrating the advantages of significantly -high yield, economic investment and low energy consumption.
