Can know consumption occupies a large proportion of the chemical industry, according to statistics, the world chemical industry energy consumption accounts for about 20% of the total energy consumption of the above, so is China. Especially in our country, recently there are many small chemical plants, energy effective utilization rate is very low, only about 23%, therefore, the chemical sector QuLiang large energy saving potential.

Energy in the chemical production, such as the chemical energy of the fuel, steam, electricity and raw materials, etc., are used to process system, therefore, its energy use is reasonable, how effective utilization is the main energy saving fields. In the chemical production, can see all kinds of process to become a "boiler", in this kind of "boiler" changing the more complicated and varied. This process also has considerable irreversibility, the energy value, thereby causing loss to the smoke, and ultimately to the visible external energy loss, therefore, reduce the smoke of all kinds of process boiler, heat exchange system and power recovery system, etc., can according to need and may be used. This section will simple chemical production, for example, use the method of thermodynamics analysis, the heat exchange system in chemical production process, the press can match, can make full use of all kinds of waste heat, to achieve the goal of energy saving.
