"By establishing rules, we should force the industrial transformation and upgrading to achieve scientific development, orderly development and high-quality development." This is general secretary Xi Jinping's exhortations to the development of the Yangtze River economic belt.

Now, three years later, the general secretary's mandate is gradually becoming a reality. Ecological protection has been integrated into the development blood of chemical enterprises and parks along the river. In the promotion of ecological and development outlook, gold waterway has also become the "gold" zone of chemical industry.

To launch the battle of tackling the key problems

The layout of chemical industry along the river and coastal area is not a unique invention of China, which is the case in most of the chemical power.

So what is the problem with the development of chemical industry in the Yangtze River Basin? The scattered layout of the East and West points in the past has been in the backward technology "Taoyi but not being eliminated", and the lack of centralized disposal capacity and collaborative development of the park.

Therefore, the renovation of chemical industry park has become an important part of the action plan for the Yangtze River Protection and restoration jointly issued by the Ministry of ecological environment and the national development and Reform Commission.

Some people laugh that "in recent years, for chemical industry parks, they are not identifying or on the way of identification.". Indeed, since 2019, the assessment and identification of the existing chemical parks by provinces and cities along the Yangtze River economic belt have been fully spread. By the beginning of May 2021, Zhejiang, Jiangsu, Anhui, Jiangxi, Hubei and Yunnan have published the list of Chemical Park identification, and six provinces have identified 200 chemical parks (including 3 cultivation parks in Zhejiang Province and 15 chemical concentration zones in Jiangsu Province). Hunan has also made public the first batch of 10 home districts identified.

After sorting out the identification methods of chemical industry parks in these 7 provinces, the reporters found that all regions took "reduction" and "quality improvement" as key words, and the park was recognized as an important grasp for the promotion and supervision of chemical industry in all provinces. The comprehensive industrial chain or characteristic product gathering, the capacity of sewage treatment and hazardous waste disposal in the park and the environmental assessment of regional planning are important evaluation indexes recognized by each province. Several provinces also explicitly proposed that new petroleum and chemical parks should be banned.

With the efforts of all parties, the chemical layout of the Yangtze River Basin is accelerating in the direction of Park oriented.

Make good example: looking for the balance between ecological protection and industrial development

Can the park layout achieve the harmonious unification of ecological protection and industrial development? Shanghai chemical industry zone has been developing for more than 20 years, which tells us: it is absolutely OK.

"Hero of theory of production per mu, benefit, energy consumption and environment" is the development direction of Shanghai chemical industry zone.

It is under the guidance of such concept that Shanghai Chemical Industry Zone ranks the top in comprehensive ranking, profit and profit margin in 2020 as the pioneer of domestic chemical park and the proponent of the "five integration" development and construction concept of the park. What's more, the development and construction of the park has not affected the migration of birds in the past 20 years.

It is a good tool to control pollution at the source of park development to improve the industrial relevance and develop circular economy along the industrial chain layout. The small cycle of enterprises, the circulation in industry and the large cycle of the park in the long-life economic development zone are the representatives.

"We have three typical circular economic industrial chains. First, the by-product chlorine gas and natural gas to methanol by-product tail gas of chlor alkali chemical industry produce MDI. The hydrogen separated from the by-product tail gas from natural gas to methanol is used to produce aniline, the key raw material of MDI is aniline. Hydrogen chloride from the by-product of MDI unit is absorbed, electrolyzed and regenerated to generate chlorine gas and high purity hydrochloric acid. Hydrochloric acid is recycled in the loop, and the brine is returned to the chlor alkali chemical enterprise as raw material, and the comprehensive utilization of hydrogen exceeds 20000 tons every year The carbon monoxide is 90000 tons and hydrogen chloride is 200000 tons. Second, the industrial chain of waste tires, fine rubber powder, tires and rubber products can be recycled and utilized more than 20000 tons of waste tires every year. Third, fly ash, smelting slag, desulfurized gypsum are used to make cement and slag, then produce slag micro powder, and finally produce cement and other building materials. The comprehensive utilization of seven industrial wastes, such as smelting slag, slag, fly ash, desulfurization gypsum, coal gangue, chemical waste and construction waste, exceeds 10million tons. " The relevant head of the Management Committee of Changshou Economic Development Zone said.

Under the guidance of ecological priority concept, a number of chemical industrial parks along the river, such as Shanghai Chemical Industry Zone, new chemical materials (Jiaxing) park of China and Yangzhou Economic and Technological Development Zone, are selected as national eco industrial demonstration park. Among the top 30 chemical industry parks in 2020, 15 are located in the Yangtze River Economic Zone, including 8 in Jiangsu, 5 in Zhejiang, 1 in Shanghai and 1 in Hubei; Seven of the top 10 are located in the Yangtze River Delta. This shows that the Yangtze River economy has brought the national chemical industry a model in the aspects of the harmonious development of park, ecological protection and industrial development.

Write new answer paper -- rapid improvement of the development quality of chemical industry along the river

In the index of competitiveness, the profit margin of sales income (hereinafter referred to as profit margin) is an important indicator“ Some chemical industry provinces have a profit margin of 3% in 2020. This is going to close here. " The reporter in Zhejiang interviewed, more than once heard such a voice.

Zhejiang chemical enterprises say this, is a base gas. According to the data provided by Zhejiang Petroleum and Chemical Industry Association, in 2020, the total profit of the National Petroleum and chemical industry will decrease by 13.5%, and the profit of Zhejiang chemical industry will rise by 14.1%, reaching 90.9 billion yuan and profit margin of 7.8%; The total amount of profits and taxes of 13.1 billion yuan also set the highest level in the 13th Five Year Plan period.

This kind of bottom gas is also reflected in the statistics of other provinces and cities along the river.

According to the data released at the 2021 China Petroleum and chemical industry economic operation press conference, the sales revenue of Enterprises above the scale of the petroleum and chemical industry will reach RMB 11.08 trillion in 2020, and the total profit will be 515.55 billion yuan. The average profit margin of the whole industry is 4.65%.

Although the data of 2020 have not been released in Shanghai, according to the data provided in the survey report on the competitiveness of chemical industry development in the Yangtze River Delta, the profit margin of Shanghai chemical industry in 2017, 2018 and 2019 is 11.12%, 10.18% and 8.43% respectively, which has been ranked the top in the country.

Chongqing is also in the forefront. According to the data provided by Chongqing Economic and Information Commission, the profit margin of chemical industry in Chongqing will reach a high level of 7.69% in 2020.

Jiangsu, as a traditional large chemical industry province, has focused on the improvement of the industry in recent years, and the overall scale has declined greatly. However, the profit rate has begun to rise. Chemical industry has become the first industry to promote the growth of industrial profit in Jiangsu Province. According to the data provided by Jiangsu Chemical Industry Association, the profit margin of main business of Jiangsu chemical enterprises in 2020 was 6.65%, 0.54% higher than that of the previous year, 2% higher than the national average profit margin.

Anhui is mainly coal chemical industry, and the industrial chain is incomplete. According to the data given in the survey report on the competitiveness of chemical industry development in Yangtze River Delta, the profit margin of the chemical industry in 2017 is 5.86%, which is lower than the national average of 6.14%; However, after adjusting the structure and changing mode, the profit margin of the chemical industry in the province has been increased to 7.49%, 6.02% in 2018 and 2019, which is significantly higher than the national average of 6.77% and 5.45%.

Hubei Province, as the middle reaches of the Yangtze River, has improved its business status by actively cultivating high-end chemical new materials, modern coal chemical industry, special chemicals and other high-end petrochemical products in recent years. In 2019, the profit margin of petrochemical industry in the province was 5.8%, which was higher than the average level of 5.45% in China. Although novel coronavirus pneumonia epidemic occurred in 2020, the profit of petrochemical industry in this province dropped by only 6.8%, which was significantly lower than that of the whole industry 13.5%. The profit margin remained at 4.7 per cent, slightly higher than the national average of 4.65 per cent.

According to the data of Sichuan Provincial Economic and information technology department, the output value of Sichuan Chemical Industry in 2020 is about 470billion yuan, and the profit of energy and chemical industry increases by 10% compared with the previous year when the revenue is 2% lower than that of the previous year.

One of the important driving forces for the chemical industry of Yangtze River economic belt is the leading enterprise's driving role and the comprehensive "premium" of independent core technology.

During the investigation and visit, the reporter saw in Yichang Yidu chemical park, Hubei province that Huayang Chemical UV absorbent project is being built towards the world with heat“ After four moves, we moved out of a new world instead of being defeated. Liaoquanhong, deputy general manager of Huayang Chemical Industry, told reporters. In 2018, Huayang Chemical industry became the first relocation enterprise in Yidu. With the help of relocation, they implemented the expansion of the unit and the upgrading of the process. Besides the investment in the UV absorber project, the products of benzophenone, salicylic acid and triazine were added, which enriched the production chain of the products, and further consolidated the position of the world's largest leading enterprise of ultraviolet absorbers.

Such leading chemical enterprises still have a lot along the Yangtze River. After sorting out statistics, the reporter found that, in the national single champion demonstration enterprises in chemical industry, nearly half of them are located in the Yangtze River economic belt. This is the best example of the rapid improvement of the development quality of the chemical industry along the river.

The construction of the Yangtze River economic belt into a gold economic belt is a new orientation of general secretary Xi Jinping's high quality development goals for the Yangtze River economic belt. In the process of ecological guidance and industrial transformation and upgrading, the Yangtze River economic belt has become a new "gold" zone of chemical industry.
