China's Shandong Lianhong Gerun 200000 t/a EVA device to achieve high standards of delivery, into the trial production stage

China, Shandong-At 9: 58 on September 26, the construction was contracted by the company. Shandong, China lianhong Gurun 200000 Tons/Year EVA Device Achieved High Standard and High Quality Zhongjiao, Successfully Achieving Key Milestones in Project Construction. This result marks the device formally transferred from the project construction phase to the linkage commissioning and trial production phase.

Wang Xiaofeng, executive director and Secretary of the Party committee of the company, Zhai Jun, deputy secretary of Zaozhuang municipal Party committee and mayor of China, Wang Guangding, member of the Standing Committee of Zaozhuang municipal Party committee and Secretary of Tengzhou municipal Party committee, Zheng Yueming, chairman of Lianhong group and chairman of Lianhong Xinke, and Xie Yaping, executive president of Lianhong Xinke and commander in chief of Lianhong grun integration project construction, witnessed this milestone moment.

Project Overview

as a major implementation project in Shandong Province, China, Lianhong Gerun Integration Project has a total investment of 12.5 billion yuan and covers an area of more than 1600 mu (about 106.7 hectares), covering:

• 200000 tons/year EVA device
• 300000 tons/year propylene oxide PO plant
• 50000 tons/year PPC biodegradable material
• 1.3 million tons/year methanol to olefin MTO plant
• 240000 tons/year PPG plant and supporting utilities, etc.

Technological Breakthrough and Core Advantages

the 200000-ton/year EVA device built by the company is the "core engine" of the integrated project, and it is also another technological breakthrough of Lianhong Company in the field of high pressure-following the application of autoclave method and tubular tail expansion technology, this device uses Basell Company's tubular reaction patented technology to produce EVA resin particles, which has the characteristics of high proportion of imported equipment, complex process flow, leading degree of automation, etc.

After the project is put into operation, it will complement the full range of high-pressure EVA products of Lianhong Company, which has important strategic value to enhance the independent control ability of China's related industrial chain.

Construction speed set a domestic record

in just 19 months, the project team completed the design, procurement and construction tasks of 18 sections, 34 plant units, as well as three-dimensional warehouses and packaging plants, which greatly shortened and refreshed the cycle from "civil construction start to CCCC" compared with similar devices. China Domestic similar high-pressure polyolefin project "construction speed".

Technical Tackling Achievements

at the technical level, the team focused on key difficulties to achieve a series of breakthroughs:

• the ultra-high pressure compressor is integrally hoisted in place without reaming the foundation conduit.
• Precision Control of High Pressure Pipeline Installation Welding Precision
• core equipment booster/primary compressor crankcase lifting accuracy up to millimeter level
• the 29.45-ton equipment was accurately placed through the 800-ton crawler crane to smoothly start the installation of the high-voltage system.
• The 35kV transformer and distribution room received power successfully at one time, building a solid energy foundation for the linkage test run of the whole device.

Industry Impact and Market Outlook

as the device enters the trial production phase, china Domestic EVA market pattern will usher in new variables. Considering the continuous strong demand for EVA film in the photovoltaic industry and the steady growth of traditional application fields such as wire and cable and foaming materials, the new production capacity of 200000 tons/year will effectively alleviate the supply pressure of high-end EVA products, and enhance the bargaining power and anti-risk ability of China's industrial chain in the global market.
