The DFD-1.36/(30~50)-250 Natural Gas Compressor is developed for industrial gas systems requiring high-capacity natural gas compression and stable pressure delivery.
Designed for desulfurized and dehydrated finished natural gas, this compressor provides a processing capacity of approximately 100,000Nm³/d (about 4,166Nm³/h).
The unit is designed with an inlet pressure range of 3~5MPa.G and a discharge pressure of 25MPa.G, making it suitable for high-pressure natural gas compression processes.
The compressor is equipped with a 315kW motor and adopts a D-type symmetrical balanced reciprocating piston structure, water cooling system, oil-free lubrication design, and two-row three-stage compression configuration.
Designed for Treated Natural Gas Compression
Natural gas quality and operating conditions can directly affect compressor selection.
The DFD-1.36/(30~50)-250 is designed specifically for treated natural gas after desulfurization and dehydration.
The compressor is suitable for systems requiring:
Stable natural gas pressure increase
Continuous gas processing capability
High-pressure gas delivery
Industrial natural gas handling
Its design focuses on matching industrial process requirements where gas composition and pressure conditions are already defined.
Compression Configuration and Gas Handling Design
The compressor adopts a D-type symmetrical balanced reciprocating piston configuration.
The main structure includes:
Two-row cylinder arrangement
Three-stage compression system
Water-cooled operation
Oil-free lubrication structure
The multi-stage compression arrangement is applied to high-pressure natural gas compression processes, while the oil-free design helps prevent lubricating oil from entering the compressed gas.
Modular Package for Industrial Projects
The DFD-1.36/(30~50)-250 is supplied as a modular compressor unit integrating the main compression equipment and auxiliary components.
The modular configuration helps:
Simplify project transportation
Support installation at different sites
Reduce on-site assembly requirements
Adapt to different project layouts
The compressor package can be configured according to customer requirements, including installation form, cooling method, and drive configuration.
