The DFWD-2.3/(28-62)-(31-64) regeneration gas compressor is custom-built for oil and gas fields, especially for Kekeya Gas Field.
Adopting proven reciprocating piston design, it delivers stable outdoor performance and adapts well to variable temperatures and harsh climates.
This compressor has a flow rate of 2.3 m³/min, with suction pressure 2.8–6.2 MPaG and discharge pressure 3.1–6.4 MPaG, ideal for regeneration gas applications needing accurate pressure control.
Driven by a 75 kW plateau-grade motor, it measures about 3500×3000×1850 mm and weighs 4 T.Its compact structure supports skid-mounted installation and saves on-site space.
Stable Operation & Gas Purity
This DFWD compressor ensures stable performance and clean gas. Single-stage compression lowers pressure loss for higher efficiency.
Siemens PLC and touchscreen enable real-time monitoring and auto protection, reducing manual operation.
High-strength parts ensure low vibration and noise (≤85dB). Oil-free design prevents gas contamination.
Rugged & Adaptable
D-type dual-cylinder structure ensures balanced, low-wear operation. HT250 crankcase supports easy daily maintenance.
Easy Maintenance & Compatibility
Manual turning device simplifies on-site service. Long-life parts reduce maintenance cost.
Skid-mounted design allows fast installation. RS485/MODBUS supports DCS connection for unattended running.
Flanges meet HG/T 20592-2009 for pipeline compatibility.
Quality & Standards
Built to API 618-2016 and GB standards. Quality components ensure reliable performance.
Strict factory tests guarantee stable on-site operation.
The DFWD-2.3/(28-62)-(31-64) Regeneration Gas Compressor is specifically developed for the efficient processing and utilization of regeneration gas in oil and gas field-related systems, with core application scenarios including:
Natural gas dehydration: Compresses regeneration gas for molecular sieve renewal, maintaining high dehydration efficiency.
Oil & gas separation: Delivers compressed gas for adsorbent regeneration, improving methane/ethane separation and gas quality.
Industrial gas purification: Supplies stable-pressure gas to restore purification equipment performance and extend service life.
Plateau oilfields: Adapted to 1830–1900m altitude and extreme temperatures, ideal for Kekeya Gas Field and similar highland sites.

| A range piston ZL 2017 2 190177.0 for symmetrical balanced compressors | | Integrated long short double compartment ZL 2018 2 0294762.0 |
The compressor adopts a D-type (symmetrical balance type), air-cooled, oil-free lubrication, reciprocating piston type, 2-row 1-stage compression, and the entire unit is supplied in a skid-mounted configuration.
The crankcase is made of HT250 gray cast iron with mounting holes for crosshead slides and bearings.It stores lubricating oil at the bottom and has ports for oil filling, breathing, oil level gauge, and temperature measurement.An external oil drain port with a manual ball valve allows easy oil draining.
The compressor uses a dual intermediate body with space over twice the stroke, effectively preventing oil from entering the cylinder and keeping regeneration gas contamination-free.
The cylinder and cylinder head are both made of QT600-3 ductile iron. The oil-free design needs no lubrication oil injection. Axial air valves ensure smooth gas flow
