Union Tech was awarded a contract consisting of Z4 rising-stem ball valves and paired actuators installed in Nanjing Chengzhi Yongqing Energy Technology’s 600 kt/a methanol-to-olefins (MTO) project in March 2018 by Wison Energy Engineering, who was the EPC for the project. The project, which converts methanol from coal and other sources into olefins that are the essential ingredients for plastic production licenses Honeywell UOP’s MTO technology. Chengzhi Yongqing’s MTO unit—which will be the operator’s second at the site—is scheduled for startup in 2019.
The contract spanned a wide range in valve sizes, from 1.5” up to 10”. Union Tech manufactured both the valves and matching linear pneumatic actuators. Final inspections were conducted and passed in August 2018 at Union Tech’s Houston, TX facilities, and the valves were subsequently shipped to the Chengzhi Yongqing MTO plant.
