Oil-free air compressor is developed by gathering oil-free engine technology for more than half a century. Only the processing technology possessed by the raw material manufacturer can make the screw rotor. The unique patent technology of oil-free air compressor can prevent the lubricant from mixing compressed air from the shaft seal even if it is continuously unloaded for a long time. The oil-free structure in the compression chamber satisfies the gas demand of petroleum and petrochemical industry.

In what areas does the petroleum and petrochemical industry need to use oil-free air compressors?

1. Hazardous Procedures: Increasing Safety

Compressed air is often used to sweep the console to maintain the safety of the platform area. Even a very small amount of oil can form a flammable environment, and the process of closing and disassembling the platform requires extremely strict oil content in the air.

2. Instrument Air: Extend Normal Working Time, Reduce Failure Frequency and Maintenance Cost

Some special instruments and control valves need to be operated and started by compressed air. The tiny amount of oil in compressed air can also cause equipment failure. Maintenance means less running time and higher maintenance time and cost. Injection compressors must regularly refuel and frequently replace filters to prevent air pollution and machine shutdown.

3. Nitrogen production: purer gas, shorter shutdown time

Nitrogen separated from compressed air by membrane separation technology will be used to form a nitrogen layer in LNG tank to transport catalyst and reactant to the downstream section. Oil-free air compressor ensures longer service life of membrane, reduces the cost of replacement and maintenance, and reduces the downtime of equipment maintenance.

4. Buffer Air: Prevent Main Process/Gas Compressor Shutdown

Large flow gas compressor needs to seal buffer air to ensure the normal operation of the equipment. In this process, even a very small amount of oil mist may cause disaster, leading to the shutdown of the main compressor. Advanced Driving Devices and Controllers: To ensure long-term trouble-free operation of equipment, a new generation of driving devices and controllers rely on compressed air to achieve normal operation. Oil in compressed air can clog key operating components and increase the risk of failure.

5. Operation process: no oil = no fault

Compressed air is used in desulfurization process, catalyst regeneration, process heater, acid oxidation and gas-oil desulfurization.

Even very small amounts of oil can lead to product contamination, equipment failure and production interruption risk.

Check and test equipment: prevent contamination and wrong reading.
