Heat exchangers are important thermal energy exchange equipment in petroleum and chemical production. They can be used as heaters, coolers, condensers, evaporators and reboilers. In recent years, with the rapid development of China's petrochemical, energy and power, environmental protection and other industries, the demand for heat exchangers has risen sharply. Large-scale engineering constructions such as ethylene projects, coal chemical projects, nuclear power plants, wind farms, environmental protection, desalination, etc. all have a huge demand for the heat exchanger industry. As a market for the heat exchanger industry, the market size of the petrochemical industry has exceeded 15 billion yuan. The equipment cost of large-scale coal chemical projects approved during the “Twelfth Five-Year Plan” period will also exceed 500 billion yuan, and the average annual growth rate of the heat exchanger industry in the “12th Five-Year Plan” of equipment investment will reach over 40%.
According to Zhang Zhongqing of the Heat Exchanger Committee of China Pressure Vessel Society, China's heat exchanger industry is mainly concentrated in Northeast China, Northwest China, North China and East China. China's "Twelfth Five-Year Plan" continues to regard energy conservation and emission reduction as a constraint indicator for national economic and social development, and proposes energy conservation and emission reduction targets for national energy consumption per unit of GDP in 2015 that is 16% lower than that in 2010. The state continues to encourage enterprises to increase investment in energy-saving and emission reduction technology and technological innovation, and enhance independent innovation capabilities.
In an interview with reporters, Cheng Zhifang, secretary general of China Chemical Machinery Power Technology Association, pointed out that many universities, research institutes and enterprises have done a lot of work in the field of new heat exchanger development and application, and have achieved some results, but The basic research of heat exchanger technology in China is still weak. In the manufacture of heat exchangers, China is still mainly based on imitation, and there is still a certain gap between the level of mold processing and the suppression of plates. In design, core technology is monopolized by foreign companies. In terms of design standards, China's heat exchanger design standards and technologies are lagging behind. The large-scale specialized heat exchanger design lacks large-scale professional software support, and it is impossible to accurately predict the product use effect, so that the product is at a disadvantage in the bidding process.
The petroleum and chemical industry is a traditional high-energy industry, and it is an important position for energy conservation and emission reduction. The task is very arduous. Further tapping the potential of energy conservation, especially the energy-saving potential of key energy-consuming industries, is an important measure to ensure the sustainable development of the petroleum and chemical industries. Large energy-consuming households in industries such as refining, ethylene, synthetic ammonia, caustic soda, calcium carbide, soda ash, and yellow phosphorus have great potential for energy conservation. Enterprises are looking forward to reducing the comprehensive energy consumption indicators of enterprises by carrying out technological innovation and deepening technological transformation. To this end, enterprises have put forward higher requirements for energy efficiency improvement of heat exchangers, and heat exchanger technology and equipment modification with remarkable energy saving and material saving effects have attracted much attention.
