Core Tip: 2014 crude oil crash, low oil prices normalized, 1 million tons / year large ethylene project again returned to the vision of many refining enterprises. On the one hand, low oil prices brought about by the substantial decline in raw material costs, so that the ethylene and chemical sector benefits a significant rebound, become a beneficiary of low oil prices. Polyethylene products, for example, 1,800 to 2,500 yuan / ton or even higher profitability, far from many other chemical products. On the other hand, the local refinery has gained the right to import crude oil and the right to export refined oil products, and the refining capacity and output have increased significantly, extending the industrial chain, entering the downstream chemical field, and investing in the 1 million tons/year large ethylene project, it becomes the
Crude oil crash in 2014, low oil prices normalized, 1 million tons / year large ethylene project once again returned to the vision of many refining enterprises. On the one hand, low oil prices have brought about a significant drop in raw material costs, which has led to a significant rebound in the efficiency of the ethylene and chemical sector, which has become a beneficiary of low oil prices. Polyethylene products, for example, 1,800 to 2,500 yuan / ton or even higher profitability, far ** many other energy chemical products. On the other hand, the local refinery has gained the right to import crude oil and the right to export refined oil products, refining capacity and production has increased significantly, extending the industrial chain, into the downstream chemical field, into the 1 million tons / year ethylene project, it becomes its continue to be stronger and bigger, improve the ability to resist risks and market competitiveness of the inevitable choice. The current domestic demand for ethylene up to 15 million tons / year of the huge gap, the state-owned petrochemical enterprises have mastered the construction of large ethylene core technology for private enterprises to enter the field of ethylene provides favorable conditions. The domestic ethylene industry is rising a new force of private enterprises.
According to incomplete statistics, from 2017 to 2021, the domestic plans for new ethylene projects will be more than 40, involving at least 24 million tons of new production capacity / year, of which the local enterprises in Shandong plans to new ethylene capacity of more than 6 million tons / year, Zhejiang Petrochemicals, Gulei Petrochemicals and Sinochem Quanzhou and other large ethylene projects of more than 1 million tons / year are also in the state of construction. Compared with previous years, the late new investment in the device, more private enterprises into the ethylene industry, to make up for the huge domestic ethylene gap at the same time, Sinopec, PetroChina, the two centralized enterprises of the ethylene market share following the encroachment of the coal chemical industry, will be attacked by private enterprises again. Private enterprises focused on entering the ethylene industry, will be in the production of technological change and downstream related markets to bring no small impact.
Subject to the harsh conditions of ethylene storage and transportation, more than 95% of China's ethylene as an intermediate product, very few involved in export sales, so ethylene downstream supporting projects are usually more complete. To 1 million tons / year ethylene project, for example, will generally choose polyethylene, ethylene glycol / ethylene oxide, styrene, EVA, PVC and other related products for the combination, the specific combination will depend on the enterprise's target market. Therefore, the competition in the ethylene industry, more focused on the competition of downstream related products, and the concentration of large ethylene projects will inevitably trigger the centralized expansion of downstream related production capacity, and the related competition intensified.
The extension of private enterprises to the chemical industry chain is advancing, and the pattern of the domestic ethylene and chemical market will be changed as a result. And how to choose raw materials, downstream products, how to support, will be the plan for new enterprises to seriously consider the issue.
Ethylene compressor demand opportunities
Ethylene is the leading petrochemical industry, derivatives accounted for more than 75% of petrochemical products, widely used in agriculture, national defense, aviation, automotive and other fields, able to geometrically pull the national economy. Calculations show that large ethylene enterprises to drive the downstream industry growth coefficient of 1:50. each million tons of ethylene production base is completed and put into operation, not only the enterprise's own sales revenue of more than 20 billion yuan, but also to drive the downstream of more than 100 billion yuan of output value of industrial investment. As the world's second largest ethylene producer, equivalent consumption self-sufficiency rate is less than 50%. Private enterprises to enter the ethylene industry and China's ethylene production growth will greatly stimulate the petrochemical industry gas compressor market demand. Produce a million tons of ethylene plant, circulating gas compressor, circulating hydrogen compressor, petrochemical pumps and other key equipment needs.
Ethylene plant is extremely complex, with more than 500 sets of equipment. For example, PetroChina Sichuan Pengzhou 800,000 tons / year ethylene project, only the refining area has: 10 million tons / year atmospheric decompression distillation unit, 3 million tons / year residue hydrodesulfurization unit, 2.7 million tons / year wax oil hydrocracking unit, 3.5 million tons / year diesel oil hydrofinishing unit, 2.5 million tons / year of catalytic cracking unit of heavy oil, 600,000 tons / year of gas fractionation device, 650,000 tons / year paraxylene aromatics unit, 90,000 Nm³/h pressure adsorption hydrogen refining unit, 900,000 tons/year aromatics extraction unit, 100,000 tons/year sulfur recovery unit. And a new 10 million tons/year refinery requires more than 30 gas compressors.
However, the number of gas compressors in the complete set of ethylene production units* is large, such as cracked gas compressor, propylene compressor, ethylene compressor of ethylene cracking unit; polyethylene device of the circulating gas compressor and ethylene compressor, polypropylene device of the circulating gas compressor and propylene compressor; PTA device and propylene plant process compressor, etc.. One of the ethylene cracking device cracking gas compressor, propylene compressor and ethylene compressor, these three sets of equipment is known as the ethylene project; the heart of the equipment. Energy consumption accounts for 20% to 40% of the total energy consumption of the device, in which any one machine failure to stop, may cause the entire device shutdown, the loss of less than tens of millions of dollars, more than hundreds of millions of dollars. The ultra-high pressure gas compressor in the high-pressure polyethylene plant is the reciprocating gas compressor with high pressure* in the petrochemical production plant, and the discharge pressure reaches 350MPa.
A new 1 million tons / year ethylene plant requires a variety of gas compressor more than 50 units, the plant as a cleaning, instrumentation and other power with the required air compressor more.
Ethylene compressor industry status
Compressor is one of the main products of the general machinery industry, known as the heart of the petrochemical and other process production areas. Ethylene industry on the main needs of the compressor is a centrifugal compressor.
Ethylene project in the equipment localization rate * high Wuhan 800,000 / year ethylene project, the localization rate has reached 87%, in the past has been the United States, Germany, France, three countries, the monopoly of five companies ethylene three machines, has also been fully localized.
