Shanghai, China – Wison Engineering has completed the construction of a 100 kilotonne per annum (ktpa) butene-to-butadiene plant for Nanjing Chengzhi Yongqing Energy Technology Co.
The facility, built at Nanjing Chemical industry Park, eastern China, also includes a 600ktpa methanol-to-olefins (MTO) plant, Chinese EPC firm Wison said in a statement.
The butadiene plant is based on Wison process technology, which involves oxidative dehydrogenation (ODH) of butene to butadiene.
The unit, officially handed over 8 May, is the first large-scale commercial application for the ODH technology.
In addition, it is Wison's first commercial project for integrating ODH technology with MTO technologies.
Wison was awarded the EPC contract in October 2017.
