换热设备是炼油、化工工业的主要工艺设备之一,钢材耗量和建设投资比重都比较大,例如对一个处理量为250万吨/年的原油常减压蒸馏装置,它的换热器钢材耗量占装置工艺设备钢材的16.5～22%左右,换热器的投资占全装置设备投资的12～16%左右;

Heat exchange equipment is one of the main process equipment in the oil refining and chemical industry. The steel consumption and investment in construction are relatively large. For example, for a crude atmospheric and vacuum distillation unit with a capacity of 2.5 million tons / year, its heat exchanger Steel consumption accounted for about 16.5 to 22% of the steel equipment process equipment, heat exchanger investment accounted for about 12 to 16% of the whole device investment;
