Petrochemicals Industry
Petrochemicals
The petrochemical industry boasts complex production processes, with facilities mostly operating in high-temperature, high-pressure, flammable and explosive environments. In fluid catalytic cracking, hydroreforming and polyolefin production, oil-contaminated compressed air will not only cause catalyst poisoning and product quality degradation, but also may trigger serious fire and explosion accidents. Therefore, oil-free air compressors are key equipment to ensure the stable, safe, long-cycle and optimal operation of petrochemical plants.
- Instrument Air System: Supplies oil-free and clean air complying with SH/T 3024 standard for plant-wide DCS control valves, ESD emergency shutdown systems and pneumatic actuators.
- Process Air: Provides flowing-assist air for polymerization reactions such as polypropylene and polyethylene, as well as combustion air for sulfur recovery units.
- Front air source for nitrogen system: Delivers oil-free raw air for PSA nitrogen generators to guarantee the quality of nitrogen replacement and protective gas.
- Equipment purging and air tightness test: Conducts oil-free dry purging for process pipelines and vessels after overhaul to prevent secondary pollution caused by oil residue.
- Laboratory and quality inspection: Provides zero-contamination clean air for gas chromatographs, analytical instruments and quality inspection centers.
✅ Eliminate potential safety hazardsPrevent oil from entering high-temperature process systems, avoid fire and explosion caused by carbon deposition, and meet HAZOP analysis requirements.
✅ Protect catalysts and productsPrevent the deactivation of expensive catalysts due to oil contamination, and ensure the optical performance and purity of chemical products such as resins and fibers.
✅ Adapt to harsh working conditionsAdopt explosion-proof (Ex d IIC T4) and anti-corrosion design, suitable for high salt spray and high humidity environments in coastal refining bases.
Widely applied in oil refineries, ethylene projects, large coal chemical plants and fine chemical production bases.
