In petrochemical production processes, vacuum systems are widely used in processes such as vacuum distillation, oil and gas recovery, vacuum degassing, solvent recovery, vacuum drying, and tail gas treatment. These working conditions are often accompanied by flammable and explosive gases, corrosive media, and high-temperature and high-humidity environments, placing strict requirements on the explosion-proof rating, corrosion resistance, and continuous operation stability of vacuum pumps. Targeting the special working conditions of the petrochemical industry, Leynow provides combination solutions of liquid ring vacuum pumps, Roots vacuum pumps, and dry vacuum pumps, forming complete vacuum system service capabilities from selection and explosion-proof configuration to installation and maintenance.
Challenges Faced by the Industry
The requirements of petrochemical plants for vacuum systems are not just about "pulling a vacuum", but more importantly, explosion-proof, corrosion-resistant, and capable of continuous operation. In practical applications, customers often encounter the following types of problems:
Risk of Flammable and Explosive Gases
Petrochemical processes are often accompanied by combustible gases or volatile solvent vapors. Vacuum pumps need explosion-proof configurations to avoid safety accidents caused by electric sparks or high temperatures.
Erosion by Corrosive Media
Corrosive media such as acid gases, hydrogen sulfide, and organic solvents accelerate the aging of the pump body and seals, shortening equipment lifespan and increasing leakage risks.
High-Temperature and High-Humidity Continuous Operation
Refining and chemical plants mostly operate continuously for 24 hours. Under high-temperature and high-humidity conditions, pump body overheating and vacuum fluctuations directly affect distillation and degassing effects.
Maintenance and Compliance Costs
Vacuum pump oil needs to be replaced regularly, and oil-containing exhaust gas needs to be treated. Combined with explosion-proof maintenance and compliance requirements, overall maintenance costs are relatively high.
