In the petrochemical process, Roots fans have the following key application technologies:

1. Compressed air supply: Roots fans can be used in compressed air supply systems. In petrochemical processes, large quantities of compressed air are required to drive equipment and control systems. Roots fans compress the air by means of rotating impellers and feed it into pipelines for supply to the relevant equipment.
2. Alternative to peristaltic pump use: In petrochemical processes, some viscous or solid particle-containing media need to be conveyed and circulated. Traditionally, peristaltic pumps are the common choice, but Roots fans can also be used as an alternative. Roots fans have highly efficient clogging resistance and conveying capacity for viscous liquids and solid particle-containing media conveying.
3. Application for exhaust gas treatment: In petrochemical processes a large number of exhaust gases are generated, including organic exhaust gases, malodorous gases and pollutants. Roots fans can be used in exhaust gas treatment systems to accelerate the decomposition and treatment process by providing sufficient oxygen and increasing airflow.
4. Flue Gas Desulphurization Systems: In petrochemicals, flue gases from combustion often need to be desulphurized to reduce environmental pollution. Roots fans can be used in flue gas desulphurization systems by providing the right amount of air into the desulphurization reactor and transporting the removed sulphur dioxide gas to subsequent treatment facilities.

These are some of the key application technologies of Roots fans in petrochemical processes. Depending on the specific situation and needs, Roots fans can also play a role in other areas, such as petrochemical catalysis and gas circulation.
