Ningbo Zhenhai Refining & Chemical Company Ltd. (ZRCC), a key subsidiary of Sinopec, has signed a technology licensing agreement with ECI Group for a new ethylene vinyl acetate (EVA) and low-density polyethylene (LDPE) plant in Ningbo, Zhejiang Province, China. The plant, designed for a capacity of 200,000 tonnes per year, will be part of ZRCC’s ongoing expansion of its integrated ethylene and downstream chemical complex in the Zhenhai District.

Details of the Licensing Agreement

Technology Scope: The agreement covers the licensing of ECI Group’s hybrid reactor technology, which merges the product versatility of an autoclave reactor with the higher throughput of a tubular reactor tail. This configuration is designed to enable the production of a broad range of high-pressure polyethylene products, including LDPE, EVA, and other high-value copolymers at larger scales, a capability that has traditionally been challenging for autoclave-based technologies alone.

Project Deliverables: ECI Group will provide the technology license, process design package, expanded process design package, and detailed design for the high-pressure system. The scope also includes technical procurement services and on-site support during installation, commissioning, and performance assessment.

Plant Integration: The new EVA/LDPE facility will be integrated into ZRCC’s large ethylene and downstream complex. ZRCC, as a Sinopec subsidiary, is a major operator in the region and has recently completed significant expansions to increase both crude oil processing and advanced materials production capacity at its Ningbo site.

Industry Context

Capacity Milestone: The contract marks a milestone for ECI Group, bringing its total nameplate licensed capacity for LDPE/EVA plants to 1 million tonnes since 2021, with projects in China ranging from 50,000 to 200,000 tonnes per year.

Strategic Expansion: The new plant forms part of NZRCC’s broader strategy to expand its portfolio of high-value specialty chemicals and polymers, supporting downstream industries such as automotive, home appliances, and textiles in the Yangtze River Delta.

Sinopec’s Role: NZRCC operates as a major refining and chemical subsidiary under Sinopec, one of the world’s largest integrated energy and chemical companies. The Zhenhai complex is a central hub for Sinopec’s advanced materials and petrochemical production in eastern China.

Sipchem announced on July 4th on Linkedin to have "signed an Engineering and procurement Sign off of its Expanded Production Capacity for High-VA  Ethylene Vinyl Acetate ( EVA) production plant."

"This investment will enable Sipchem to produce innovative EVA grades designed to support downstream production of Solar Encapsulate Cells as well as certain Hot Melt Adhesives." the company stated. 

The production plant, based on ExxonMobil's tubular reactor technology, belongs to International Polymers Company, a subsidiary JV of Sipchem and Hanwha Solutions Corporation, and is installed in Al-Jubail, 🇸🇦 KSA. 

With a design capacity of 200,000 tpa, the plant is thought to be running at close to 220,000 tpa. Debottlenecking by an additional 70,000 tpa will bring the plant output close to 290,000 tpa.

The company declined to comment on the engineering solution that will be employed to increase the plant capacity.
