Hengyi Petrochemical: From "a drop of oil" to "two threads"

This company once gave birth to the country's first large-capacity polyester melt direct spinning device and the country's first pure private purified terephthalic acid (PTA) project, forming a unique "polyester + nylon" double" among domestic counterparts.
This company is also the first domestic private enterprise to invest and build an integrated refining and chemical industry in China, and it has truly realized the development of the entire petrochemical industry chain from "a drop of oil" to "two threads"
.

Unique to double "lun" drive mode

Entering the exhibition hall of Hengyi Petrochemical R&D Center, the first thing that caught the reporter's eyes was the glass bottles placed on the table, which contained various products produced by Hengyi Petrochemical
.

Wang Songlin, executive vice president of Hengyi Petrochemical, said that the current two main product lines of Hengyi Petrochemical are polyester and nylon.
The company has formed a unique "polyester + nylon" dual "lens" driving model among domestic counterparts
.

"Our products are related to the national economy and people's livelihood, as well as the basic life of people's clothing, food, housing and transportation.
PTA is an important raw material for the textile industry, used to produce polyester chips, long and short polyester fibers; polyester (PET) is widely used in the manufacture of clothing fabrics, home textiles and industrial products; Nylon (PA6) has excellent performance and high abrasion resistance, and can be made into textiles, industrial yarns and carpets
.

　　According to Zheng Xingang, secretary of the board of directors of Hengyi Petrochemical, the current PTA production capacity of Hengyi Petrochemical is 16 million tons/year, and the PTA production capacity is 3 million tons/year under construction; the isophthalic acid (PIA) production capacity is 300,000 tons/year , Caprolactam (CPL) production capacity is 400,000 tons/year; polyester production capacity is 7.
765 million tons/year, under construction, it is planned to increase polyester fiber production capacity of 1.
85 million tons/year; polyester bottle flake production capacity is 2 million tons/year, and the production capacity is At the forefront of the industry
.

　　"The average cost of the company's PTA is at the lowest level in the industry, and has maintained strong profitability in the market
.

　　In Zheng Xingang's view, the company's existing and future polyester production capacity has two major advantages
.

　　"China's polyester filament production capacity has accounted for more than 70% of the world.
The greater the production capacity, the more secure the cash flow
.

　　The advantages of overseas refineries are highlighted

　　Accompanied by the roar of the machine, the research team came to the spinning workshop
.

　　"The raw material for the production of filaments is PTA, and the raw material for PTA is petroleum.

　　In order to improve the industrial structure and create an integrated industrial chain, Hengyi Petrochemical went to Brunei to invest in the construction of PMB petrochemical projects
.

　　Zheng Xingang said that Hengyi Petrochemical Brunei project has four major advantages
.
One is the advantage of crude oil procurement
.
With the liberalization of the Brunei market, crude oil can be purchased to select the most suitable and most profitable raw materials for the refinery
.
Because the company's raw material procurement and product sales teams are located in Singapore, they can do some hedging or lock-in related product spreads more flexibly, and they can better resist the risks of market fluctuations
.

　　The second is product sales advantages
.
So far, except for chemicals such as paraxylene (PX) that have to be shipped back to China for processing, other refined oil products have been sold in Southeast Asia and Oceania, and the sales have been smooth
.

　　The third is the processing cost advantage
.
The public works of the factory are self-provided to save costs
.
The Brunei refinery has its own power plant, gas and electricity linkage, coal is purchased from Indonesia, transportation distance is short, and the price of coal is low, thus reducing the cost of public works of the refinery
.

　　The fourth is the advantage of production and operation
.
The company has flexible inventory control and product structure adjustment conditions
.
Affected by the epidemic in the first half of the year, crude oil prices fluctuated significantly.
During this process, some products and crude oil prices were inverted, including aviation kerosene and gasoline
.
The company quickly adjusted its product structure and transformed jet fuel and gasoline into higher value-added products
.
This also reflects the advantages of private enterprises in the agile transformation of product structure on the existing basis
.
For aromatics, the current added value is still considerable, and the company guarantees that its load is 110% and above
.

　　"Currently the second phase of the project has also started, with an additional crude oil processing capacity of 14 million tons per year.
The project plan mainly includes four parts of'refining, aromatics, ethylene, and polyester', and the four related industrial chains will achieve a high degree of integration
.
" Zheng Xingang said
.
After the Brunei Refining and Chemical Phase II project is completed and put into operation, the "ethylene-propylene-polypropylene" industrial chain will be added, which will help improve the intensification, scale and integration of the Brunei Refining and Chemical Integration Project and enhance the company's continued profitability.
Ability and anti-risk ability
.
Based on the three-year construction period of the Brunei Phase I project, the Brunei Phase II project is expected to start contributing new performance increments in 2024
.

　　The second phase of the Brunei project will also make full use of the remaining public works of the first phase to support downstream deep processing projects
.
It is reported that Hengyi Group has signed a framework agreement with Wanhua Chemical for the second phase of the project
.
This cooperation can greatly increase the depth of project integration, effectively enhance the comprehensive competitiveness of the project, and further improve the integrated layout of the upstream and downstream of Hengyi's industrial chain.
It is expected that Brunei Phase II will be built into an internationally leading petrochemical industrial park
.

　　Take a good green and low-carbon road

　　In the exhibition hall of Hengyi Petrochemical R&D Center, a facial mask aroused the interest of the research team.
Can Hengyi Petrochemical products be used as a mask?

　　Wang Songlin said that the "mask paper" used in this mask is made of the antimony-free environmentally friendly polyester "Yitaikang" with independent intellectual property rights of Hengyi Petrochemical, which fundamentally avoids the potential of heavy metal precipitation in the "mask paper".
Risk
.

　　It is understood that the development of the antimony-free environmentally friendly polyester "Yitaikang" product successfully broke through the bottleneck of the application of titanium catalyst in polyester, and promoted product upgrading
.
Relying on this polyester green manufacturing technology, the problem of antimony pollution has been solved from the source, the wastewater treatment costs of downstream enterprises have been effectively reduced, and a green, healthy and environmentally friendly industrial ecology has been truly built
.
This project won the first prize of Zhejiang Province Chemical Industry Science and Technology Progress Award in 2020
.

　　"The company has always attached importance to technological innovation.
In 2020, we applied for 164 patents, including 113 invention patents and 51 utility models
.
" Wang Songlin said that the company established a post-doctoral research station in 2003 and passed the national enterprise technology center certification in 2006.
In 2007, he won the second prize of the National Science and Technology Award.
In 2018, the Hengyi Petrochemical R&D Center-Zhejiang Henglan Technology Co.
, Ltd.
was established.
In 2019, the company established three major universities, enterprise, industry, research and research with Zhejiang University, Donghua University, and Nanjing University of Technology.
Platform
.

　　Wang Songlin said that the company strives to create green manufacturing of polyester throughout its life cycle
.
At present, the company is developing new products such as biodegradable polyester and bio-based polyester.
In the future, it hopes to achieve high-efficiency degradation of nylon and polyester through key technology research in order to achieve green development
.

　　Zheng Xingang stated that Hengyi Petrochemical will actively respond to the policy of “carbon peak and carbon neutrality” during the 14th Five-Year Plan period, reduce energy consumption costs of polyester and nylon, and maximize energy consumption and material consumption in the industrial chain through new technologies and new processes.
, Reduce carbon emissions
