China Drying Network Co., Ltd. cooling (condensation) equipment is an important basic equipment widely used in the industrial field, and it is also a device with high energy consumption and water consumption. According to statistics, cooling (condensation) equipment consumes 13% to 15% of industrial energy. In 2006, the first high-efficiency compound cooling (condenser) was put into use in China. The highly efficient compound evaporative cooling (condenser) technology has been applied to the cooling and condensation of process gases in the petrochemical industry such as methanol, synthetic ammonia, and urea. , The energy-saving effect is remarkable. It is estimated that by 2015, this technology can be promoted to 70% in petrochemical, coal chemical and other industries, and can form an annual energy saving capacity of 250,000 tons of standard coal. Fang Xiaoyu, deputy director of the China Chemical Industry Energy Technology Association, told reporters that the demand for cooling (condensation) equipment in the coal chemical, petrochemical, metallurgical, electric power, and refrigeration industries mainly includes two aspects: on the one hand, expansion of production capacity and industrial integration upgrades. New demand for new equipment brought about by new fixed asset investments; on the other hand, it is driven by policies such as the national energy conservation and emission reduction, the implementation of energy-saving and water-saving reforms, and the need for equipment renewal. Luoyang Longhua Heat Transfer Technology Co., Ltd. independently developed a highly efficient compound evaporative cooling (condenser) technology by the China Petroleum and Chemical Industry Federation, the China Chemical Industry Environmental Protection Association as "petroleum and chemical industry environmental protection and cleaner production key support "Technology" was again included in the fifth batch of national key energy conservation technology promotion catalogues. “Compared with traditional cooling (condenser) technology, high-efficiency composite evaporative cooling (condenser) technology has the advantages of energy saving, environmental protection, etc. Compared with air cooling, the energy saving rate is 30% to 60%; The full-load rate of island operations can reach 95% or more; compared with traditional water-cooling, the water-saving rate can reach 40% to 50%, said Dong Xiaoqiang, general manager and senior engineer of Luoyang Longhua Company. At present, this technology has been successfully applied to petrochemical enterprises such as Sinopec Changling Branch, Sinopec Yangzhou Branch, Sinochem Hongrun Petrochemical Co., Ltd., Sichuan Shida Chemical Co., Ltd., and Shandong Chenhao Petrochemical Co., Ltd. Experts from the Petrochemical Federation believe that the technology has promoted structural adjustment and industrial upgrading of the petroleum and chemical industries, met the urgent needs of the petroleum and chemical industries for energy-saving emission reduction technologies and equipment, and solved the pollution control, clean production, and energy saving of the petroleum and chemical industries. The problems in emission reduction work have played a positive role. “The use of a compound evaporative cooling scheme to replace the water cooler solution currently used in the industry has resulted in significant economic benefits. For example, a 600,000-ton-per-year coal-to-methanol project has been transformed into a heat exchanger, with a general investment of approximately RMB 9 million, and six construction periods. In the month, 1188 tons of standard coal can be saved every year, but the annual energy-saving economic benefits can reach 2.32 million yuan, and the investment can be recovered in 4 years.†Dong Xiaoqiang said, “A set of 100,000 tons of methanol synthesis ammonia is used for compound evaporation with energy-efficient complete sets of equipment. After the cooler is put into use, it can save more than 67% of water, save more than 58% of electricity, and save more than 60% of the integrated energy-saving rate. The benefit is very impressive. I believe that such a good technology will replace the water cooler with high energy consumption. It has been widely used in our methanol/synthetic ammonia plant." At present, Luoyang Longhua Company has developed a series of equipment for the heat exchange process used in the production of different petrochemical products. For example, its self-developed high efficient compound evaporative cooler for methanol synthesis of ammonia is the first new type of high-efficiency energy-saving complete set for methanol (synthetic ammonia) in China. It fills the gap of the energy-saving set of the frequency conversion evaporative air cooler for methanol (synthetic ammonia) in China. SYL series (petrochemical) high efficiency cooler is specially used in the petrochemical industry. It is based on the basic theory of latent heat exchange and sensible heat exchange. Various cooling methods such as evaporative, air-cooled, and water-cooled are optimized and the structure is stable and reliable. The use of a wide range, with energy, water, environmental protection and other significant advantages. The reporter learned that these equipment and technologies have achieved very good results in chemical companies: Hubei Yihua carried out heat exchange process transformation at its six nitrogen fertilizer companies, all of which use this type of evaporative heat exchange equipment. It is estimated that an annual output of 100,000 tons of urea transformation project will recover only 8.8 tons of water per hour for tail gas recovery, 124 kilowatts of electricity saving, more than 2,000 tons of liquid ammonia recovered annually, and saving operating costs of about 6.8 million yuan; Shandong Union Chemicals In the methanol, synthetic ammonia, urea and other projects are used in this equipment, the methanol heat exchanger device than the traditional heat exchanger equipment without increasing the investment under the premise of saving 40%, saving 45%, annual operating costs to reduce more than 200 million .
