140,000 tons of polycarbonate project announced, targeting high-end differentiated products
140,000 tons of polycarbonate project announced, targeting high-end differentiated productsIn January 2021, the environmental impact report of Wanhua Chemical's 140,000-ton polycarbonate (PC) project with an annual output of 140,000 tons was announced before approval.
The project is located in Yantai Chemical Industrial Park, Yantai Economic and Technological Development Zone, Shandong Province.
100,000 tons of ordinary PC production equipment, a set of special PC equipment with an annual output of 40,000 tons, and corresponding storage and transportation, public works, environmental protection engineering and auxiliary production facilities; part of the storage and transportation, public works, environmental protection engineering and auxiliary production facilities of this project The facilities need to rely on the existing and under-construction projects in Wanhua Chemical Plant
.
Since 2015, with the rapid growth of China's market demand for polycarbonate, domestic independent research and development of PC production technology has made breakthroughs, and the release of foreign monopoly technology has set off a climax of polycarbonate construction in China.
PC production and the market have reached a balance, and there will be a surplus of domestic bulk low-end products, while high-end differentiated products are still monopolized by a few foreign companies, and the gap is expanding
.
Wanhua Chemical's self-developed phosgene method for interface polycondensation PC production technology has high product quality and can be used as a raw material for high-end materials to meet the needs of differentiated high-end products.
It also takes into account the production of silicon-copolymerized PC.
Through continuous optimization of the process, device consumption and production costs are reduced.
, Continuously improve product quality, and develop products according to user needs through PC modification and alloy product research and development, downstream new field market development, and provide long-term and stable innovation and development power and growth benefits for enterprises
.
Relying on the existing PC plant and the bisphenol A plant under construction, the technology is reliable, mature and advanced
Relying on the existing PC plant and the bisphenol A plant under construction, the technology is reliable, mature and advancedWanhua Chemical relies on the existing PC plant to carry out in-depth process optimization and technical adjustment, and then invests in the construction of a 140,000-ton/year PC production unit.
The PC device produces raw material supply, in order to achieve the company's strategic goal of developing new chemical material products with phosgene as raw material, thereby enriching the company's product categories, broadening the industrial chain, improving the company's economic benefits, and enhancing the company's comprehensive market competitiveness
.
The bulk raw materials required for PC production—BPA, phosgene, hydrochloric acid, caustic soda, etc.
are connected in series with the isocyanate and ethylene industry chains.
The comprehensive resource utilization rate of the park is high, and the market risk is small.
There are PC devices and existing facilities in the park for processing, advanced production technology, environmental protection, complete treatment of three wastes, saving investment, and meeting the relevant requirements of national environmental protection policies; it can also reduce material consumption and energy consumption, improve labor productivity and economic benefits, in order to achieve clean production Process control provides favorable conditions
.
In addition, the existing propylene industry chain of Wanhua Petrochemical segment and the future phase II project of large ethylene can provide raw materials such as propylene and benzene for the production of bisphenol A, which can ensure the safe and stable supply of raw materials
.
Wanhua Chemical's construction of PC devices fully embodies the company's development ideas of integration, park, scale and refinement: the industrial chain is extended to upstream raw materials to achieve integrated development, and public works rely on existing or under-construction devices in the park to produce The scale of the device has gradually expanded with technological progress, and the products have been continuously developed towards high-end
.
According to the EIA report of Wanhua Chemical's 140,000-ton PC plant, the unit consumption of bisphenol A for ordinary PC is about 0.
875 ton/ton, and the unit consumption of bisphenol A for special PC is about 0.
7 ton/ton
.
Wanhua Chemical plans to build a bisphenol A plant of 480,000 tons, which can supply more than 550,000 tons of PC demand.
The park has an existing PC production capacity of 200,000 tons and plans to build 140,000 tons.
The upstream raw material bisphenol A can ensure the continuous expansion of PC scale in the future.
.
Years of research and development layout, technology is completely independent research and development
Years of research and development layout, technology is completely independent research and developmentIn 2014, Wanhua Chemical established a project with an annual output of 200,000 tons of polycarbonate (PC)
.
The interfacial polycondensation phosgene method PC production process used in the project was completely developed by Wanhua Chemical, and has passed the total annual production capacity.
The actual production verification of the 200,000-ton 1# and 2# PC units shows that the technology has become more mature and perfect
.
The first phase of the 70,000 t/a interface phosgene polycarbonate (PC) unit has been successfully completed in early 2018.
Production and output of high-quality qualified products; the second phase will be completed and commissioned in May 2020.
This series of products has been widely recognized in the market, and many well-known brand customers at home and abroad have reached a 2018 strategy with Wanhua Chemical cooperation agreement
.
Driven by research and development, aiming at the global leader in new materials
Driven by research and development, aiming at the global leader in new materialsThe global outbreak of the new crown epidemic in 2020 and the slump in oil prices have brought huge challenges to the company's business development.
However, the company continues to invest in research and development, and develop processes and technologies with independent intellectual property rights.
In the first three quarters of 2020, the company spent 1.
427 billion yuan , an increase of 17.
74% year-on-year, accounting for 2.
90% of operating income (an increase of 0.
40 percentage points year-on-year)
.
The company's newly built Wanhua Global R&D Headquarters was officially put into use
.
At the same time, Wanhua University completed the unveiling ceremony on June 20, 2020
.
In 2020, in terms of innovative application of MDI, the company developed a technical solution for automatic sizing of formaldehyde-free plywood and successfully piloted it; in terms of material solution development, the company has newly launched a variety of modified PP, modified PC, water-based resin, TPU and other functional new products, and gradually establish the company's comprehensive technical solutions for collaborative innovation of various materials in the fields of automobiles and consumer electronics
.
At the same time, the company accelerated the layout of downstream fine chemicals and new materials related fields
.
Wanhua further clarified the strategic positioning of the three major industrial clusters of polyurethane, petrochemicals, fine chemicals and new materials, accelerated the construction of projects under construction, and accelerated the industrial transformation of new products
.
The company continued to increase the research and development of high-end chemicals, continued to promote the research and development and industrialization of nylon 12, citral and other projects, completed the merger and integration work of the Fujian base, the polyolefin modification of the Meishan base was put into production, and the Yantai ethylene project was put into high-quality trial operation.
