CNG Gas Compressor Skid

High-Pressure CNG Compression Systems for Gas Filling, Storage, Transfer & Industrial Applications

Aegis Projects Technology Pvt. Ltd. provides engineered CNG Gas Compressor Skids designed for the controlled compression, transfer and handling of Compressed Natural Gas (CNG) across industrial, commercial and energy applications.

CNG compressor skids combine the compressor, drive system, cooling equipment, controls, instrumentation and associated auxiliary components into an integrated package. This skid-mounted arrangement simplifies installation and allows the compression system to be configured according to the requirements of the project.

Aegis Projects’ CNG compression solutions can be considered for applications including CNG filling stations, high-pressure gas storage, cascade filling, gas transfer, daughter stations, mother stations, pressure boosting and industrial natural gas systems.

Depending on the application, compressor configurations can be selected according to required gas flow, suction pressure, discharge pressure, compression stages, cooling method, drive arrangement and installation conditions.

What is a CNG Compressor Skid?

A CNG compressor skid is an integrated high-pressure gas compression package used to increase the pressure of natural gas for storage, transportation, dispensing or process applications.

Instead of installing individual compressor and auxiliary components separately, a skid-mounted system brings the major equipment together on a common structural base.

A typical CNG compressor skid may incorporate:

  • Reciprocating gas compressor
  • Electric motor or other suitable drive
  • Gas cooling system
  • Lubrication system, where applicable
  • Gas filtration
  • Pressure and temperature instrumentation
  • Control panel
  • Safety and protection systems
  • Valves and piping
  • Skid frame and equipment supports

The exact configuration depends on the application and project requirements.

Key Features & Advantages

High-Pressure Natural Gas Compression

CNG compressor skids are designed to increase the pressure of natural gas to the level required for storage, dispensing, transfer or downstream process applications.

Multi-stage reciprocating compression can be utilized where high pressure ratios require staged compression and interstage cooling.

Integrated Skid-Mounted Package

Major compressor equipment and auxiliary systems can be arranged on a common skid structure.

This can simplify:

  • Transportation
  • Equipment positioning
  • Site installation
  • Piping connections
  • Electrical integration
  • Commissioning
  • Maintenance access

Reciprocating Compressor Technology

Reciprocating piston compressors are widely suited to applications requiring high-pressure gas compression.

The positive-displacement operating principle allows the compressor configuration to be selected according to the required flow and pressure conditions.

Multi-Stage Compression

For high-pressure CNG applications, the compression system can be configured with multiple stages.

Interstage cooling and appropriate separation arrangements can be incorporated according to the compressor design and process requirements.

Flexible Drive Options

Depending on the project, the compressor package can be configured around an appropriate drive system, such as:

  • Electric motor drive
  • Explosion-protected motor where required
  • Other project-specific drive arrangements

Motor selection depends on compressor capacity, pressure ratio, operating conditions and site requirements.

Automated Control & Monitoring

CNG compressor skids can incorporate control and instrumentation systems for monitoring important operating parameters.

Typical monitoring points may include:

  • Suction pressure
  • Discharge pressure
  • Gas temperature
  • Interstage pressure
  • Interstage temperature
  • Motor condition
  • Lubrication parameters, where applicable
  • Compressor operating status
  • Safety alarms

The final control philosophy can be configured according to the requirements of the CNG installation.


Applications

Aegis Projects CNG compressor skids can be used for a variety of natural gas compression applications.

CNG Filling Stations

The compressor package can be integrated into CNG stations to compress natural gas for high-pressure storage and vehicle dispensing systems.

CNG Mother Stations

CNG compression systems can be used at mother stations where natural gas is compressed and loaded into high-pressure cascade systems for further transportation or distribution.

CNG Daughter Stations

For daughter station applications, compressor and gas handling equipment can be configured according to the station’s gas supply and pressure requirements.

High-Pressure CNG Storage

CNG compressor skids can be used to fill high-pressure storage cascades and buffer vessels.

The compressor and storage system are selected based on the required filling pressure, flow rate and operating cycle.

CNG Cascade Filling

The compressor package can be integrated with cascade storage systems for controlled high-pressure gas filling.

Natural Gas Transfer

CNG compression systems can support controlled transfer of natural gas between storage, transportation and downstream equipment.

Industrial Natural Gas Applications

CNG compressor skids can also be considered for industrial facilities requiring high-pressure natural gas for process, energy or gas distribution applications.


Typical CNG Compression System

A typical CNG compression installation may consist of:

Natural Gas Inlet → Filtration → Compressor → Interstage Cooling → Gas Separation → Final Compression → Aftercooling → High-Pressure Storage / Dispensing

The actual process configuration depends on the station design, gas source, required pressure, flow capacity and storage arrangement.


Technical Configuration

A CNG compressor skid can be engineered around several important parameters.

Gas Flow

The required flow rate determines the compressor displacement and overall equipment capacity.

Suction Pressure

The compressor must be selected according to the available natural gas pressure at the compressor inlet.

Discharge Pressure

The final discharge pressure is determined by the intended application, such as high-pressure cascade storage or CNG dispensing.

Compression Stages

Multiple compression stages may be used where a large pressure increase is required.

Cooling

Interstage and final gas cooling can be incorporated to manage gas temperatures and support efficient compression.

Drive Power

Motor power is selected according to compressor capacity, pressure ratio, gas properties and operating conditions.


Safety & Protection

CNG systems operate with high-pressure natural gas, requiring appropriate process and equipment safety measures.

Depending on the project, a CNG compressor skid may incorporate:

  • High-pressure relief systems
  • Emergency shutdown systems
  • Pressure monitoring
  • Temperature monitoring
  • Gas leakage detection
  • Automatic shutdown protection
  • Overload protection
  • High-discharge-temperature protection
  • Suction-pressure protection
  • High-pressure protection
  • Appropriate isolation valves
  • Explosion-protected electrical equipment where required
  • Proper grounding and bonding

The final safety arrangement should be designed according to the natural gas composition, operating pressure, hazardous-area classification, applicable standards and project-specific requirements.
