Indeed, environmental protection is a big problem for chemical parks. How to realize the harmony and unity of efficiency and environmental protection in the chemical park? Experts put forward the concept of “intensive environmental protectionâ€, which means to use the concentrated production advantages of the chemical park to carry out environmental protection. PetroChina has taken the lead in this regard, and its chemical parks in Lanzhou, Dalian, Fushun, Dushanzi and other places have embarked on this path.
The centralized production and concentrated development of chemical companies has become an international trend instead of scattered production. For example, South Korea's ethylene production has been concentrated in the three major coastal cities. Another example is that Singapore is a tourist city, but Asia’s largest refinery is built on seven islands around Singapore, and its refining capacity is 20 to 30 million tons, mainly Shell’s products. Why can Singapore have such a large refining capacity? Marine transportation and crude oil supply and market demand in Asia are important reasons. In addition, Rotterdam in the Netherlands and Antwerp in Belgium are the world's top chemical cities. Houston, United States, is located in the Gulf of Mexico and is rich in oil and natural gas. Houston therefore concentrates 80% of the US's ethylene production capacity.
Compared with foreign chemical cities, the scale of chemical parks in China is still very small, especially the environmental protection model is still in a relatively deferred backward stage or primary stage. Yang Weicai, vice president of the China Petroleum and Chemical Industry Association, reminded that as long as there is no problem in the development direction of the park, it will take a long time for China's chemical parks to do a good job, become bigger and stronger. Do not expect to build a world-class one in three to five years. Chemical Industry Park.
The so-called intensive environmental protection is the unified collection and transportation of waste pollutants in the chemical industry park, centralized management, and emission collection. It is conducive to improving the efficiency and quality of waste disposal and the centralized management of the entire park. This kind of environmental protection has been very common in developed countries. In our country, it is still in its infancy. Although China has also developed a number of chemical parks, the degree of environmental protection intensive in the park is not high, and some are still at the stage of decentralized processing, thus constraining the overall quality of the park.
In the intensive environmental protection production model, the environmental protection index has become a “high threshold†for enterprises to enter the chemical industry park. Some chemical companies, even if they are strong, should be rejected if their production processes, production processes or products fail to meet the standards. Environmental protection standards are hard targets. Only those companies and projects with low technological content and high environmental pressure are firmly prevented from entering the park, and environmental protection in the park can be guaranteed. The intensive production model has been widely promoted in many fine chemical industry parks of China National Petroleum Corporation. Some parks have adopted the form of hiring expert groups and setting up expert committees to evaluate the production environment of the enterprises in the park, and to comply with the principle of controlling the old and controlling new projects and constructing the same. The requirements will gradually improve the environmental conditions of the park, and eventually reach the full discharge standards of the park.
The implementation of a circular economy strategy and the establishment of conservation-oriented parks are effective ways to achieve the sustainable development of chemical parks. At the same time, Yang Weicai reminded that the construction of the chemical industry park must adhere to the principle of unifying environmental benefits, economic benefits, and social benefits. It can use economic levers to encourage enterprises to increase resource and energy efficiency, reduce pollutant emissions, and promote enterprises. Cleaner production and take a new road to industrialization. At the same time, optimizing the industrial structure, conducting environmental assessments for enterprises entering the park, and accelerating infrastructure construction are also ways to achieve the environmental protection development of the chemical park.
Needless to say, the development of the park economy is the trend of the development of the chemical industry in the future, and it is the trend of the times. However, people in the industry have warned that the development of the chemical park economy must be tailored to suit local conditions. It should not blindly pursue comparisons and comparisons. We must focus on long-term development and focus on the direction that is conducive to sustainable development. In our country, some localities blindly go on projects and engage in chemical and construction parks. Because the current chemical parks are mostly built in developed regions, developed regions tend to have high population density and few cultivated lands. This development model is obviously not in line with the sustainable development strategy. Moreover, this kind of development model actually wastes not only land resources, but because the environmental protection facilities in this park cannot meet the standards, it is easy to become a “hard-hit area†for environmental protection. For example, if a fine chemical plant is built in some places, one hectare of land will suffice. However, the number of square kilometers must not be increased. It is not a big park, but it does not seem to be chemical city or chemical industry park. In fact, this understanding is incorrect.
Industry experts pointed out that the next five years will be an opportunity for the development of China's chemical industry park. However, the construction of the chemical industry park cannot be flocked to the top, and it must adhere to the principle of gradual and orderly adaptation to local conditions. In particular, environmental protection issues, the park must adhere to the "high starting point, high standards, strict system, heavy punishment" principle. To achieve such a goal, adopting an intensive environmental protection model is an effective way to achieve a sustainable economic development of the park.
Intensive Environmental Protection: The Threshold of Chemical Industry Park Construction
With the rapid development of the chemical industry, the chemical industry park has rapidly emerged in China as a form of development with high energy recycling and low pollution. However, when it comes to the chemical park, it is reminiscent of the sky and the pungent odor in the air covered by thick smoke, as well as waste water and sewage flowing everywhere, and some even describe the chemical park as a “pollution parkâ€.
