Sulzer supplies pumps for ambitious PTA expansion project
Sulzer is providing 87 pumps for a variety of applications in Hengli Petrochemical (Huizhou)’s latest purified terephthalic acid (PTA) plants. The equipment will be used in two new processing units at Daya Bay Petrochemical Park, Huizhou, China, to support a total production capacity of 2x2.5 million tons per year.
With design and manufacturing taking place at Sulzer’s local facility in Suzhou, the 87 process-specific pumps include 15 PRESF single-stage, end suction units. Featuring semi-open impellers that are able to handle the slurries involved in PTA processing, the PRESF is said to be ideally suited to this application.
Each pump is individually engineered to their intended application, leveraging materials to withstand the process conditions. This includes Hastelloy, a high specification material with excellent resistance to corrosion and erosion, as well as pumps made with stainless and Duplex steel.
A spokesperson for Hengli said: “Sulzer’s local engineering and manufacturing capabilities combined with its proven pump designs are very important to us. These are helping us to create efficient production processes and enhance our competitiveness in the PTA market.”
Wu Dongqing, sales manager at Sulzer, added: “We are delighted by Hengli Petrochemical’s feedback. All of our local facilities are backed by our extensive, global engineering network. Thanks to this key capability, we can promptly offer our customers advanced solutions to any application, ultimately improving their competitiveness in the marketplace.”
Construction of Hengli Petrochemical (Huizhou)’s new PTA plants is expected to be completed by the end of 2021, with operations scheduled to start in the second quarter of 2022.
