Description

ZW-0.8/16-24 Liquefied Gas Compressor

Oil-Free LPG Reciprocating Compressor for Unloading, Transfer, Filling & Gas Recovery

The ZW-0.8/16-24 Liquefied Gas Compressor is an industrial-grade oil-free reciprocating compressor designed for handling liquefied petroleum gas (LPG) and other low-boiling, volatile hydrocarbon gases.

The compressor is designed for applications including LPG unloading, loading, transfer, cylinder filling, vapor recovery and gasification systems, where reliable gas handling and controlled compression are important.

Featuring a Z-type reciprocating structure, the compressor is designed for stable operation with relatively low vibration and noise. Its configuration makes it suitable for continuous-duty industrial environments and a variety of LPG storage, distribution and refueling facilities.

The compressor can also be configured for compatible liquefied gas applications involving propane, butane and butene, while specialized variants may be considered for propylene and liquid ammonia, depending on the required gas properties and operating conditions.


Product Overview

The ZW-0.8/16-24 uses a reciprocating piston compression system with an oil-free configuration, making it suitable for gas handling applications where minimizing oil contamination is important.

Its industrial design allows the compressor to be integrated into different LPG process systems, including storage facilities, unloading stations, filling plants and vapor recovery installations.

The compressor can be configured according to the requirements of the installation, with options covering compressor structure, cooling arrangement, installation method and drive system.


Key Features & Advantages

Oil-Free LPG Compression

The oil-free compressor configuration helps minimize oil contamination in the compressed gas and supports applications where clean gas handling is required.

This makes the compressor suitable for LPG transfer, unloading, filling and recovery operations.

Z-Type Reciprocating Structure

The Z-type reciprocating configuration provides positive-displacement gas compression and is designed for stable operation during continuous industrial service.

Efficient & Reliable Operation

The compressor is designed for dependable operation in LPG and liquefied gas handling systems. Its configuration supports automated operation while reducing the need for continuous manual intervention during normal operation.

Low Vibration & Noise

The compressor is designed to operate with relatively low vibration and noise, helping improve equipment operating conditions and making routine operation more convenient.

Reduced Maintenance Requirements

The compressor structure is designed with attention to component durability and accessibility, supporting easier inspection and routine maintenance.

A straightforward mechanical arrangement can also help reduce maintenance workload and minimize unnecessary equipment downtime.


Flexible Configuration Options

The ZW-0.8/16-24 series can be configured according to specific project requirements.

Compressor Structure

Possible compressor configurations include:

  • D-Type
  • M-Type
  • V-Type
  • W-Type
  • Other project-specific configurations

Cooling Options

Depending on operating requirements, the compressor can be configured with:

  • Water cooling
  • Air cooling

Installation Options

The compressor can be supplied according to the site installation arrangement, including:

  • Skid-mounted configuration
  • Fixed installation

Drive Options

Depending on project requirements, drive systems may include:

  • Electric motor drive
  • Diesel engine drive

The final configuration should be selected according to the gas medium, required capacity, pressure conditions, site environment and project-specific process requirements.


Applications

The ZW-0.8/16-24 Liquefied Gas Compressor can be integrated into a wide range of LPG and liquefied gas handling systems.

Typical applications include:

  • LPG storage and distribution stations
  • LPG loading systems
  • LPG unloading systems
  • LPG tanker unloading
  • LPG cylinder filling plants
  • LPG bottling and canning facilities
  • LPG vapor recovery systems
  • Gasification stations
  • Gas mixing stations
  • Automobile LPG refueling stations
  • LPG transfer systems
  • Residual gas recovery

The compressor is suitable for small, medium and large LPG stations, subject to the required flow, pressure and process configuration.


LPG Loading & Unloading

The compressor can be incorporated into LPG loading and unloading systems to support controlled gas transfer between tank trucks, storage vessels and process equipment.

Its reciprocating compression configuration provides the pressure differential required for suitable LPG transfer operations.


LPG Cylinder Filling & Bottling

The compressor can be used in LPG filling and bottling facilities where controlled gas transfer is required between storage systems and filling equipment.

Its oil-free configuration is suitable for applications where minimizing contamination during gas handling is an important consideration.


LPG Vapor Recovery

The ZW-0.8/16-24 can be incorporated into LPG vapor recovery systems to recover residual gas from storage vessels, transfer lines and other process equipment.

This can support recovery operations during LPG transfer, vessel emptying and related handling processes.


Applicable Liquefied Gas Media

The compressor is primarily intended for LPG and compatible low-boiling liquefied gases.

Typical applications may include:

  • LPG
  • Propane
  • Butane
  • Butene
  • Mixed liquefied gases

Specialized variants may also be configured for:

  • Propylene
  • Liquid ammonia

The suitability of the compressor for a particular gas must be confirmed according to gas composition, pressure, temperature, material compatibility, sealing requirements and the intended process application.


Installation & Skid-Mounted Configuration

For projects requiring simplified transportation and installation, the compressor and associated auxiliary equipment can be arranged as a skid-mounted package.

A packaged skid arrangement can provide:

  • Easier equipment transportation
  • Simplified site installation
  • Organized equipment layout
  • Reduced installation work
  • Easier integration with process piping and utilities

The final skid arrangement depends on the compressor configuration and project requirements.


Safety Considerations

LPG, propane, butane and similar liquefied gases can present significant flammability and pressure-related hazards. Appropriate process and equipment safety measures should therefore be incorporated into the complete installation.

Depending on the application, the system should be evaluated for:

  • Pressure relief systems
  • Emergency shutdown arrangements
  • Gas detection
  • Explosion-protected electrical equipment
  • Gas-tight piping and connections
  • Appropriate ventilation
  • Isolation valves
  • Pressure and temperature monitoring
  • Grounding and bonding
  • Gas-compatible seals and components

For propylene and ammonia applications, additional gas-specific safety and material compatibility requirements should be evaluated.

The final installation should comply with the applicable engineering standards, hazardous-area requirements and project-specific safety specifications.


Customization & Project Integration

Aegis Projects can support project-specific configurations based on the required operating conditions.

Customization considerations may include:

  • Gas type and composition
  • Flow requirement
  • Suction pressure
  • Discharge pressure
  • Cooling method
  • Compressor structure
  • Installation arrangement
  • Skid configuration
  • Electric motor or diesel drive
  • Control system
  • Instrumentation
  • Safety and protection systems
  • Process piping integration

This flexibility allows the compressor to be adapted for different LPG storage, distribution, unloading, filling and recovery projects.
