Air compressors play a critical role in the petrochemical industry. Whether in refineries, fertilizer production, gas conversion, or petroleum refining, air compressors are widely used in gas compression, gas transportation, and control systems to ensure stable and efficient production processes. Our high-performance air compressor products meet the stringent requirements of the chemical and petrochemical sectors, providing you with reliable technical support.

Key Application Areas

Fertilizer Production: Ammonia, Urea, Nitric Acid

In fertilizer production, air compressors supply compressed air to drive critical equipment such as control systems, gas supply systems, and cooling systems. Precise pressure control ensures uniform gas mixing within reactors, thereby enhancing yield and product quality.

Refineries: MTBE, FCC

In refineries, air compressors are widely used in fluidized catalytic cracking (FCC) units for gas transportation, gas flow regulation, and steam recovery, ensuring efficient and energy-saving reaction processes. Additionally, gas treatment in the MTBE production process relies on high-efficiency air compressors.

Gas-to-Liquids (GTL) and Coal-to-Liquids (CTL)

In GTL and CTL processes, air compressors play a critical role in syngas generation, gas compression, and recirculation systems, ensuring stable gas pressure and enhancing reaction efficiency.

Gaseous Aromatics Production: PTA, Phenol, Caprolactam, Maleic Anhydride

In gas-to-aromatics production, air compressors are responsible for supplying clean, dry air, ensuring an adequate supply of oxygen for reactions, and compressing gas in distillation and gas treatment systems.

Syngas Production: Hydrogen, Carbon Monoxide

In syngas production, air compressors are used to supply the required oxygen or air to reactors and provide a stable gas flow in the gas circulation system to improve gas conversion efficiency.

Ethylene/Propylene and Polyolefin Production

In ethylene cracking and propylene production processes, air compressors are used not only to supply air to reaction furnaces but also for compression and gas regulation in gas recirculation systems, ensuring the stability and continuity of the production process.

Mechanical Steam Recovery (MSR)

In steam recovery systems, air compressors drive steam turbines to help recover energy from waste gases, thereby improving energy efficiency and reducing resource waste.

Petrochemical production is characterized by high temperatures, high pressures, flammable and explosive conditions, and continuous operation, placing extremely high demands on air compressors:

• Safe and Continuous Production
  A failure in instrument air supply can directly lead to a plant-wide shutdown or even safety incidents. Air compressors must operate 24/7 without failure; redundant design and extremely high reliability are essential requirements.
• Stringent Air Quality Requirements
  ISO 8573-1 Class 0/1 standards mandate oil-free, moisture-free, and dust-free air to prevent catalyst poisoning, valve sticking, and pipeline corrosion. Air compressors must be equipped with precision after-treatment systems.
• High-Temperature Corrosive Environments
  Petrochemical sites feature high levels of salt fog and sulfides, with ambient temperatures reaching 50°C and above. Air compressors must feature IP55 protection, corrosion-resistant coatings, and high-temperature shutdown protection.
• Extreme Energy Efficiency Requirements
  Air compressor energy consumption accounts for 15%–30% of total energy use in petrochemical utility systems. Energy-efficient Class 1 units can save millions in annual electricity costs and reduce carbon emissions.
