Ebara circulating water system solution was successfully applied in Shinpu Chemical’s 500,000 tons per year polyvinyl chloride project!

As one of the five general-purpose resins, polyvinyl chloride plays a vital role in the modern industrial system due to its wide range of applications, profound impact on industrial development and endless development potential.

Project Background

The 500,000-ton annual polyvinyl chloride project of Xinpu Chemical (Taixing) Co., Ltd. is located in Taixing Economic Development Zone, Jiangsu Province. As a key project of Xinpu Chemical to strengthen and supplement its supply chain, the project started construction in December 2022, was completed in December 2024, and will be put into trial operation in early 2025.

The project adopts ethylene polymerization technology to prepare polyvinyl chloride, which has the advantages of high resource utilization efficiency, good environmental performance, easy control of production process and large production scale, which is in line with the development direction of the park’s refinement, high-end and green development. The project will form a closed loop with Xinpu Chemical’s existing 900,000 tons of vinyl chloride (VCM) unit and 750,000 tons of caustic soda unit, and realize the efficient recycling of raw materials and energy through the public pipeline corridor in the park, further strengthen the synergy effect of the chlor-alkali industry chain, enhance Xinpu Chemical’s market competitiveness in the field of polyvinyl chloride, and inject new impetus into the company’s development.

As a long-term supplier of water pump equipment and related products to Xinpu Chemical, Ebara Zibo has formulated a scientific and reasonable circulating water system solution for this project, supplying a total of 4 sets of Ebara C-type horizontal double-suction split case pumps. This series of pumps has excellent hydraulic performance and adopts advanced double-suction structural design. Under large flow and high head conditions, it has high operating efficiency, saving operating costs while ensuring that the water pump can operate safely and stably for a long time.

High-quality product delivery is inseparable from a comprehensive production guarantee system. During the project execution, the Ebara Zibo project team tried its best to meet the project requirements, and multiple departments cooperated to ensure that key parameters such as pump operating efficiency, head, flow rate, etc. could fully meet the project requirements, and successfully completed the on-site installation and commissioning and put it into operation smoothly.

The split-center design of the shell is easy to disassemble and repair;

Advanced double-suction structure design can ensure large flow and high head;

Compared with traditional double-suction pumps, when equipped with high-speed motors, the installation area of ​​the pump system and associated equipment is small;

It has high operating efficiency in a wide flow range, which can reduce operating costs and select smaller power motors;

Low noise and vibration when the pump is running;

A variety of material combinations allow the pump to be used in a wider range of fields.
