Large-scale petrochemical equipment market demand

With the increasing scale of petrochemical enterprises, the large-scale petrochemical equipment market corresponding to this trend is showing strong demand.
As early as the early 1960s, the developed countries of the world's oil refining industry began to transform large-scale refineries, and large-scale oil refining companies represented by Exxon's Baytown Refinery and St. Croix Refinery emerged. . By the late 1980s, due to the increasingly fierce market competition, the increase in the size of devices was of greater concern. Large-scale refinery equipment has obvious advantages. According to the report of the US Department of Energy, compared with the construction of a 10 million-ton/year oil refinery and two 5-million-ton/year oil refineries, the investment can save about 20% and increase the labor productivity by 21%; 1 block of 10 million tons/year Compared with the four 2.5-million-ton/year oil refineries, the refinery cost can be reduced by US$0.15/m3. According to the research report of the former Soviet Union, the production cost of a 12-million-ton/year oil refinery can be reduced by 12% to 15% compared with two 6-million-ton/year refineries.
At present, among the 127 refineries in China, there are 50 processing capacity of over 1 million tons/year, and 27 processing capacity of over 5 million tons/year. In order to fully reflect the advantages of large-scale refinery, we must first realize the large-scale refinery equipment, otherwise it will be “nothing for riceâ€. Compared with small unit equipment, large unit equipment has obvious comprehensive economic benefits in terms of manufacturing costs, floor space, pipeline valves and many other factors. For example, to build an oil depot with a storage capacity of 600,000 cubic meters, use four 150,000-cubic-meter oil storage tanks, save 14.75 million yuan more than using six 100,000-cubic-meter oil storage tanks, and build one million tons per year. In the delayed coking unit, two coke drums with a diameter of 8400 mm were selected and the investment of 8.8 million yuan was saved compared to the use of four coke drums with a diameter of 6000 mm.
Large-scale petrochemical equipment is also conducive to manufacturing companies to increase output value, reduce costs and increase economic efficiency. For example, when a manufacturer undertakes a petrochemical plant with a unit weight of 1,000 tons and two similar units with a unit weight of 500 tons, the total purchase price is roughly the same. However, the cost of materials and processing used to manufacture one large device is 30% to 40% lower than that of producing two smaller devices. Usually, a manufacturing company can manufacture a large-scale equipment within the delivery period required by the user, but it is impossible to complete the manufacture of two identical equipment with the same total weight in the same time, that is, within the same period of time. Create the same value and benefit. It can be seen from this that it is a way for manufacturing companies to increase their economic efficiency, as well as a good opportunity given by the era to manufacturing companies.
Nowadays, in refineries, the large-scale development of pressure vessels has made great progress. For example, the volume of storage tanks has reached 240,000 cubic meters, the diameter of coke drums has reached 8840 mm, and the diameter of hydrogenation reactors has reached 3,800 mm. At present, China's large-scale refinery and coal liquefaction projects that are being designed or are in the approval stage will require a number of extra-large pressure vessel equipment: for example, 150,000-500 meters 3 to 200,000 meters 3 crude oil storage tanks and 9.4 to 10.6 meters in diameter coke drums , Catalytic regenerators with a diameter of 14 to 15 meters, vacuum decompression towers with a diameter of 12 to 16 meters, coal liquefaction hydrogenation reactors with a diameter of 4.8 meters and a weight of approximately 1,900 tons, which provide a broad development for pressure vessel manufacturers. space.
