The projects in the new Zhangpu site’s first development phase were started up successfully under the great teamwork of Valmet and Liansheng, creating a new world record to start up complex projects in such short time. The advantages of Valmet’s technologies, our entire unique offering combining process technologies, services and automation, and our local commissioning and startup capabilities are the main factors for Liansheng to choose Valmet as a supplier for this Phase II project in Zhangpu base,” says Zhu Xiangdong, Area President, China, Valmet.
