Actually the province is divided into four equal shares————Reflections on the status quo of China's ethylene project construction (on)
Ethylene is the leading device in the petrochemical industry. Its production of ethylene, propylene, butadiene and aromatics is a basic raw material for petrochemical industry. The size of ethylene production is an important indicator to measure the development level of a country's petrochemical industry.
After more than 40 years of development, China’s ethylene industry ranks fourth in the world and has entered the ranks of the world's largest petrochemical countries, accumulating rich experience. However, there are still some unclear and unreasonable points in the scale and layout of ethylene plants. For example, how to build a large-scale ethylene plant under the current state of technology and national conditions? What are the technical difficulties? How is China's ethylene industry more rational and economical? These issues have become the focus of attention of relevant state departments and industry professionals.
At present, China's ethylene industry is centered on major companies, provinces, and cities. This form of building ethylene units will cause the spread of ethylene facilities in China, which will cause certain difficulties for the scale, socialization, and specialization of public utilities and public facilities. It will also bring problems to environmental governance and increase investment, weakening The product's competitiveness in the international market.
Judging from the ethylene industrial layout, China still has 31 provinces, municipalities, and autonomous regions in addition to Taiwan, Hong Kong, and Macao. Among them, 12 provinces, municipalities, and autonomous regions already have ethylene industry, accounting for 39% of the total administrative area. According to current plans, Several administrative districts are also preparing for the ethylene industry. In this way, more than half of our administrative regions will build an ethylene industry. Not only that, some administrative regions have built several ethylene industries. For example, Liaoning Province has already established three petrochemical bases based on the ethylene industry in Liaoyang, Panjin, and Fushun, and is also preparing to build a large-scale ethylene plant in Dalian. The same provincial-built ethylene plant has also failed to Same area.
In contrast, the construction of ethylene plants in the world is mainly focused on construction. For example, the United States has almost the same land as China. It has a total of about 45 sets of ethylene devices, of which 29 sets are built in Texas, mainly in the Gulf of Mexico. It accounts for 60% of the total number of ethylene plants in the United States, and Texas ethylene production accounts for nearly 68% of the total ethylene production in the United States. Los Angeles 12 sets accounted for 27% of the total number of ethylene units, Los Angeles ethylene production accounted for 24% of total ethylene production in the United States. It can be seen that the construction of ethylene plants in the United States is very concentrated.
The new address is to set up a set of ethylene and its associated post-processing joint devices, from production devices to auxiliary facilities and living facilities, which is equivalent to a small society. The investment in general, auxiliary facilities, and other facilities of China's petrochemical complexes is higher than in developed countries. This is mainly due to the high concentration of ethylene equipment in developed countries, and some public facilities, utilities, and regulatory agencies have been socialized. For the centralized layout of ethylene equipment, after preliminary analysis, due to the full reliance on the old equipment, the investment in general, auxiliary and other facilities can be reduced by about 20%. Taking an ethylene project in China as an example, a new 440kt/a ethylene plant and ancillary facilities are newly added to the original ethylene project with a scale of 380kt/a. This will enable us to fully utilize and rely on the established facilities and infrastructure. The construction investment is about 4 billion yuan, and the cost savings are mainly reflected in the reliance or partial reliance on the original ethylene project for public works, general plan transportation, sewage treatment, air separation and air pressure stations, and power supply, and the land acquisition and relocation fees are also low. A total investment of about 840 million yuan can be saved, accounting for 21% of the project construction investment.
In areas with good market and traffic conditions, under the conditions of guaranteed raw materials, good overall facilities, and good public works conditions, such as adequate water sources and meeting environmental protection requirements, adopting centralized petrochemical installations has the following advantages: Transportation facilities can be shared, such as railways, highways, docks, etc.; utility facilities can be socialized, such as water supply and drainage, power supply, water supply, instrument wind, nitrogen, etc.; raw materials, intermediate products and product storage tanks can be socialized; auxiliary workshops such as machine repair , instrument repairs, electrical repairs, laboratory tests, warehouses, and environmental protection facilities such as sewage treatment plants can be socialized; enable post-processing to reach economic scale, and processing of products and by-products can also reach a reasonable scale, so that by-products can be fully utilized; Can reduce the source of pollution.
For this reason, the author suggests that the layout of the ethylene industry must be relatively concentrated. On the one hand, we must combine existing ethylene reform and expansion to adjust the layout; on the other hand, we must vigorously guide and gradually form a relatively concentrated ethylene industrial base in China through the new ethylene project, focusing on the gradual establishment of 1 to 2 coastal areas like the coast of Mexico. A large-scale ethylene industrial base that is centrally located in Antwerp, Belgium. With regard to the specific distribution of ethylene, several large oil and petrochemical companies should be organized by the state to select the optimal point through the bidding method for construction projects and focus on investment and construction. These local governments in provinces and municipalities should no longer fight for the project.
At the same time, in order to avoid excessive dispersion of the ethylene industry, I also recommend that the relevant state departments organize petroleum, petrochemical industries and enterprises, and pay close attention to the development plan of the ethylene industry. Based on the layout and scale of the ethylene industry approved by the state, the tender selection and selected construction units will, in accordance with the planning and layout, focus on the construction of ethylene projects, and gradually form a large-scale petrochemical base with ethylene plants in China as a leader.
