Wison Engineering, the largest private sector chemical engineering, procurement and construction management (EPC) service provider in China, has successfully started up its designed methanol-to-olefins (MTO) plant featuring its proprietary technology.

The plant, designed by Wison Engineering, is located in the Nanjing Chemical Industry Park. It has successfully produced qualified ethylene and propylene products which meet the requirements set for polymer products, with a passing rate of 99.98% and 99.8% for ethylene and propylene products respectively.

This marks the first commercialization of Wison Engineering’s olefin separation technology for MTO plants. It also demonstrates another successful commercialization case of China’s coal-to-olefins technology, which will facilitate the coal-to-chemical industry development roadmap in China, according to company officials.

With planned annual production of 300,000 tpy of ethylene and propylene, the MTO plant is one of the production units of Wison (Nanjing) Clean Energy. Following the commissioning of the first Shenhua Baotou coal-to-olefin project, this is the first MTO project in the world to apply advanced industrial MTO technology from Honeywell's UOP.

The Wison Engineering olefin separation technology featured in the MTO project utilizes itsproprietary “pre-cutting and oil absorption" technology, which reduces energy consumption and lowers investment costs while also improving the olefin recovery rate, allowing for more stable production and bringing longer operating cycles.

This technology broke the bottleneck in the technological difficulties that existed in the domestic industry, according to Wison officials. As a result, the China National Petroleum & Chemical Planning Institute selected it to be the recommended technology for the “Twelve-Five Coal-to-Olefins Upgrade Demonstration Project”, making it one of Wison Engineering’s core technologies.

The close cooperation between Wison Engineering and UOP on the technological front has pushed forward the development of domestic MTO technology and the upgrading of the modern coal-to-chemicals industry.

Since its development in 2007, Wison Engineering’s separation technology in MTO plant has obtained four domestic invention patents and one invention patent in Indonesia. The technology has been adopted by enterprises such as Shandong Yangmei Hengtong Chemicals, Shenhua Xinjiang New Materials (神华新疆新材料),Jiangsu Sailboat Petrochemical and Pucheng Clean Energy.

In addition to providing proprietary technology and process package design, Wison has also been commissioned to undertake the basic design, overall design and detailed engineering services of this MTO project as well as its ancillary and utility facilities. The company was also involved throughout the entire project construction phase.
