Description
DFW-2.3/(28-62)-(31-64) Regeneration Gas Compressor
Oil-Free Reciprocating Compressor for Molecular Sieve Regeneration & Gas Treatment Systems
The DFW-2.3/(28-62)-(31-64) Regeneration Gas Compressor is an industrial reciprocating compressor designed specifically for regeneration gas circulation in oil and gas processing and gas treatment systems.
Unlike conventional natural gas compressors primarily intended for gas transportation or pipeline boosting, this compressor is designed for process applications where regeneration gas must be circulated and pressurized to restore the performance of adsorption and purification equipment.
With a flow rate of 2.3 m³/min, an intake pressure range of 2.8–6.2 MPa.G, and an exhaust pressure range of 3.1–6.4 MPa.G, the compressor provides controlled regeneration gas circulation for continuous industrial process operation.
The unit features a D-type symmetrical balanced reciprocating piston structure with oil-free compression, combined with an air-cooled configuration, making it suitable for process installations requiring clean gas compression and reliable long-term operation.

Key Features & Advantages
Designed for Regeneration Gas Circulation
The DFW-2.3/(28-62)-(31-64) is specifically intended for regeneration gas systems used in gas treatment and purification processes.
The compressor provides the circulation and pressure increase required for regeneration gas to pass through process equipment and support the restoration of adsorption capacity.
Suitable for Molecular Sieve Dehydration Systems
The compressor can be incorporated into molecular sieve dehydration units, where regeneration gas is circulated through adsorption equipment during the regeneration cycle.
Stable gas circulation is important for maintaining the operating performance of the downstream dehydration system.
D-Type Symmetrical Balanced Structure
The compressor uses a D-type symmetrical balanced reciprocating piston arrangement designed to reduce mechanical vibration during piston movement.
The balanced structure supports mechanical stability across the specified operating pressure range and is suitable for continuous process operation.
Oil-Free Compression
The oil-free compression configuration helps minimize the possibility of lubricating oil entering the regeneration gas stream.
This is particularly relevant for gas treatment applications where contamination of downstream adsorption or purification equipment needs to be minimized.
Benefits include:
- Cleaner regeneration gas
- Reduced contamination risk
- Improved compatibility with purification equipment
- Reduced oil carryover into the process gas
Air-Cooled Configuration
The compressor uses an air-cooled configuration, eliminating the need for a dedicated cooling-water system for compressor cooling.
This can be advantageous for outdoor industrial installations or projects where cooling-water availability is limited.
Skid-Mounted Package
The compressor is designed as an integrated skid-mounted package, supporting simplified project installation and equipment integration.
A skid-mounted arrangement can help simplify:
- Equipment transportation
- Site positioning
- Process piping connection
- Utility connection
- Commissioning
- Equipment integration
Applications
The DFW-2.3/(28-62)-(31-64) Regeneration Gas Compressor is primarily intended for gas treatment and process gas circulation applications.
Typical applications include:
- Molecular sieve dehydration units
- Natural gas purification systems
- Regeneration gas circulation systems
- Oil and gas processing facilities
- Gas treatment plants
- Industrial gas purification projects
- Adsorption-based gas treatment systems
- Process gas circulation systems
Molecular Sieve Regeneration
Molecular sieve systems are commonly used for removing moisture and other impurities from gas streams.
During regeneration, heated or treated regeneration gas is circulated through the molecular sieve beds to remove accumulated moisture and restore adsorption performance.
The DFW-2.3/(28-62)-(31-64) can be integrated into this regeneration loop to provide the required gas circulation and pressure increase.
A typical process arrangement may include:
Regeneration Gas → Compressor → Heater / Process Equipment → Molecular Sieve Bed → Regeneration Gas Return
The exact process configuration depends on the design of the gas treatment plant.
Natural Gas Purification Applications
The compressor can also be used in natural gas purification systems where regeneration gas circulation is required for adsorption or purification equipment.
Its oil-free compression configuration helps minimize the introduction of lubricating oil into the regeneration gas circuit.
Oil & Gas Processing Systems
The DFW-2.3/(28-62)-(31-64) is suitable for integration into broader oil and gas processing facilities where regeneration gas needs to be circulated between process equipment.
Potential installations include:
- Gas dehydration systems
- Gas purification units
- Adsorption systems
- Process gas treatment plants
- Gas processing facilities
Operating Pressure Range
The compressor is designed for an intake pressure range of 2.8–6.2 MPa.G and an exhaust pressure range of 3.1–6.4 MPa.G.
This pressure range allows the compressor to support regeneration gas circulation across different process operating conditions.
The actual operating point should be selected according to the process design, regeneration cycle and gas properties.
Installation & Process Integration
The skid-mounted configuration allows the compressor package to be positioned and integrated with the existing gas treatment system.
Typical integration considerations include:
- Suction and discharge piping
- Regeneration gas circulation loop
- Process isolation valves
- Pressure monitoring
- Temperature monitoring
- Control and instrumentation
- Safety protection systems
- Electrical supply
- Equipment foundation and support
The final piping and instrumentation arrangement should be determined according to the project’s process flow diagram and engineering specifications.
Safety & Process Considerations
Gas treatment facilities can operate with high-pressure hydrocarbon and process gas streams, making appropriate engineering and safety controls essential.
The complete installation should be evaluated for:
- Pressure relief and protection systems
- Gas-tight piping and connections
- Pressure and temperature monitoring
- Emergency shutdown arrangements
- Appropriate ventilation
- Gas detection where required
- Isolation valves
- Electrical and hazardous-area requirements
- Proper grounding and bonding
- Suitable process gas sealing systems
The final safety configuration should be established according to the gas composition, operating pressure, temperature, hazardous-area classification, applicable standards and project-specific requirements.
