unloading compressor for process gas transportation

The unloading compressor can handle ammonia, Freon, ethane, ethylene, propane, propylene, butene, dimethyl ether, difluoroethane, and many other gases, providing efficient and safe gas transportation solutions for the chemical, energy, storage, and transportation industries.

Features of the Unloading Compressor

1. Integrated design: Whole set structure, no need for additional ancillary equipment, easy installation, and space-saving.
2. High efficiency and energy saving: Optimized gas conveying system reduces energy consumption and improves operational efficiency.
3. Convenient operation: High degree of automation, smooth operation, easy maintenance, and long service life of wearing parts.
4. Strong adaptability: Offers various lubrication methods, structural forms, and installation types to suit different working conditions.
5. Safe and reliable: Designed to industrial standards with multiple safety protection mechanisms to ensure operational safety.

Working Principle of the Unloading Compressor

The core principle is based on gas pressure changes, achieving fluid transfer by compressing and conveying the gas.
1. Gas intake: Low-pressure gas enters the compression chamber via the inlet (pressure range: 0.3–0.55 MPa).
2. Compression and pressurization: Piston or rotor movement compresses the gas, raising exhaust pressure up to 0.75–1.15 MPa.
3. Promotion and transportation: The pressure difference drives the gas or liquefied gas to the storage tank or pipeline.
4. Residual gas recovery: After unloading, residual gas can be recovered to reduce waste and improve economic efficiency.

Application Fields of Unloading Compressor

1. Gas storage and transportation industry: Used for loading and unloading gas tankers to improve transportation efficiency.
2. Petrochemical industry: For transporting and recovering flammable, explosive, or corrosive gases (e.g., ethylene, propylene, dimethyl ether).
3. Energy industry: For natural gas, LPG station filling, unloading, and gas recovery.
4. Refrigeration industry: Used with ammonia, Freon, and other refrigerants—ideal for cold chain logistics and refrigeration equipment manufacturing.
5. Environmental protection industry: For industrial residual gas recovery, reducing emissions and improving resource utilization.

Composition Classification of the Unloading Compressor

• Lubrication mode:
  • Pressure lubrication type: For high-load, high-speed conditions; provides stable lubrication.
  • Splash lubrication: For medium-load conditions; simple structure and low maintenance costs.
• Structure form:
  • Single-bar vertical: Compact, small footprint, suitable for small gas transport.
  • Double-bar vertical: For medium gas flow, smooth operation, stable pressure.
  • Symmetrical balanced type: Reduces vibration, increases operational stability, suitable for large flow conditions.
• Installation mode:
  • Fixed type: For long-term industrial use, offers high stability.
  • Mobile: For multi-station or temporary gas transport, highly flexible.
