The VW-9.1/(0.05~0.1)-5 corrosion-resistant low-pressure natural gas compressor from Bengbu United Compressor handles corrosive gas with chloride ion below 300ppm steadily.
Fitted with a 55kW motor, it runs at 500Nm³/h flow, 5~10KPa.G inlet pressure, 25-40℃ inlet temp and 0.5MPa.G discharge pressure. Approx. 3500×2200×1800 mm, ~5T compact unit for narrow sites.
It serves oil & gas fields for associated gas recovery, shale gas and coalbed methane exploitation, plus LNG BOG recovery, pre-liquefaction boosting and peak shaving.
This corrosion-resistant low-pressure gas compressor cuts energy use with automatic control to reduce manual operation errors. Less wearing parts deliver stable continuous running, low vibration and noise, lowering long-term maintenance costs.
V-type water-cooled oil-free 2-row 2-stage reciprocating piston skid-mounted unit for easy transport and installation.
Double middle body avoids oil pollution to gas medium. Anti-corrosion cast iron cylinder adapts to chloride-containing gas below 300ppm, with axial air valves for high compression efficiency.
Bengbu United Compressor offers tailored solutions for the VW-9.1/(0.05~0.1)-5 to meet specific project needs. Customization options include:
· Structural forms: D-type, M-type, S-type, W-type, V-type, or Z-type, adapting to spatial constraints.
· Cooling methods: Water-cooled (standard for this model), air-cooled, or mixed cooling, based on environmental conditions.
· Installation types: Fixed, mobile, skid-mounted (standard), or cabin-type, ensuring flexibility across sites.
· Drive modes: Motor-driven (standard with 55kW power) or diesel engine-driven, matching power supply availability.
