transfer compressor with booster function for LPG unloading

transfer compressor is a key equipment used for gas compression and transmission, which is widely used in the fields of chemical, energy and petroleum industries. It is suitable for unloading, loading and dumping of liquefied gases, ammonia, Freon and other gases, as well as process operations such as residual gas recovery and residual liquid recovery.

Its main function is to transfer gas from one container (such as a tanker or storage tank) to another and pressurize the gas, completing storage, distribution, loading, and unloading operations.

Technical Parameters of Transfer Compressor

Compressed gas: Liquefied gas
Flow rate: 0.8 m³/min
Inlet pressure: 1.0 MPa
Discharge pressure: 1.6 MPa

Working Principle of Transfer Compressor

The compressor transports gases from low pressure to high pressure areas using mechanical power. Gas is compressed through internal cylinders, increasing its density and pressure. Upon entering, gas has a low inlet pressure; after compression, its volume decreases and pressure rises to the desired discharge pressure (e.g., 1.6 MPa). These pressurized gases can then be piped to downstream equipment or storage tanks.

1. Lubrication: Pressure or splash lubrication ensures mechanical components are well-lubricated, reducing friction and wear for longer equipment life.
2. Structural design: Available in single-bar vertical, double-bar vertical, and symmetrical balanced forms, ensuring smooth and efficient operation.

Features of Transfer Compressor

Integrated design: All equipment is skid-mounted, requiring no additional ancillary equipment. This facilitates transport and installation, while improving stability and efficiency.
Energy saving and high efficiency: Carefully designed for energy efficiency and lower operating costs. Optimized structure and lubrication allow continuous, efficient operation and reduced energy waste.
Easy to operate: Simple, user-friendly interface with automation functions—suitable for different environments and operators.
Easy maintenance: Long-lasting, easy-to-replace wearing parts reduce maintenance costs and downtime, ensuring long-term efficient operation.

Application Areas of Transfer Compressor

Chemical industry: For storage, transportation, and processing of various chemical gases (ammonia, chlorine, Freon, etc.), used in fertilizer, plastics, refrigeration, and other processes.
Energy industry: For loading, unloading, and transportation of natural gas and liquefied gas, vital in production and distribution processes.
Oil industry: Used in oil refining and storage for handling petroleum gases such as propylene, ethane, and other products.
Cold chain logistics: Ensures safe, efficient transportation of liquefied gases in refrigeration and logistics industries, preventing temperature fluctuations and gas leakage.
Environmental protection and residual gas recovery: Used in residual gas recovery systems to reduce emissions and ensure environmental safety.
