Is there a large amount of air compressor used in chemical plants?

Chemical plant air compressor consumption is usually large, for the following reasons:

wide range of 1. application scenarios

in chemical plants, compressed air is widely used in various production processes, such as pneumatic conveying, pneumatic stirring, pressurization of the reactor, and cleaning of equipment. These applications have a large demand for compressed air, so the annual consumption of compressed air in chemical plants is usually high.

2. Factors Affecting Compressed Air Consumption

1. scale of production: Chemical plants with larger production scales usually require more compressed air to support their production activities.
2. Process flow different processes have different demands for compressed air. For example, certain chemical reactions may require high pressure compressed air to facilitate the reaction.
3. Equipment efficiency the efficiency of the equipment will also affect the consumption of compressed air. Efficient equipment may reduce waste of compressed air, while inefficient equipment may increase consumption.
4. Operating habits the habits of the operator will also affect the consumption of compressed air. For example, improper operation may result in leakage or waste of compressed air.

3. estimation method

to estimate the annual consumption of compressed air in a chemical plant, the air consumption of all equipment using compressed air in the chemical plant can be considered and calculated in combination with the operating time of the equipment. In addition, the actual gas consumption data of chemical plants of similar size and production process can be used for estimation.

4. practical cases and data support

1. gas consumption of equipment in chemical plants, large pneumatic equipment (such as grinding machines and sandblasting machines, etc.) may work continuously for a long time. Although the overall utilization rate is not high, the air consumption is still large.
2. System Design Considerations when determining the design air volume of the instrument compressed air system, it is necessary to comprehensively consider the air consumption of the pneumatic instrument, the maximum consumption of process gas, the purging of the analyzer, the pressurization of the electric instrument in the explosion-proof area, and the air consumption of the pneumatic logic system. According to these calculations, the sum of the air demand is multiplied by a certain coefficient (such as 1.2), and then considering the special needs of adding some instruments and abnormal working conditions after the factory starts, a certain amount of air supply (such as 25%) should be added.
3. Energy consumption ratio pumps and compressors for chemical industry are the most widely used general machinery in chemical enterprises, and their power consumption accounts for a large proportion of the total power consumption of enterprises. Specifically, pump equipment accounts for 65% of the total power consumption of enterprises, and compressors account for about 25%.
