Blackmer launches NGH100 Series of oil-free reciprocating gas compressors for oilfield applications

March 6, 2017

Blackmer, part of PSG, a Dover company and a global leader in positive displacement, regenerative turbine and centrifugal pump, and reciprocating compressor technologies, has introduced its new NGH100 Series Horizontal Oil-Free Reciprocating Gas Compressors. NGH100 compressors have been designed to optimize operational capabilities in a wide variety of critical oilfield production operations, including wellhead transfer, artificial lift, and vapor recovery.

Blackmer NGH100 compressors are highly efficient horizontal opposed units featuring a non-lubricated design available in heavy-duty single-stage (NGH1013) and two-stage (NGH1023) configurations. A key operational characteristic of NGH100 compressors is their ability to handle sour gas that contains up to 8% dry hydrogen sulfide (H2S), which is a flammable, extremely hazardous byproduct of recovered crude oil and natural gas.

To enhance their compatibility with sour gas, the NGH100 compressors feature select parts (that follow National Association of Corrosion Engineers guidelines) in all gas-containment areas. They incorporate steel wrist pins that ride on steel needle bearings for extra life under severe operating conditions. NGH compressors are constructed of ductile iron with a balanced forged-steel crankshaft. Piston rings and rider bands are made of PTFE/PEEK.

NGH compressors have the capability to handle wet and dry gas, and offer flexible cylinder sizes for various flow rates and pressures and motor-speed capabilities up to 1,800 rpm. These compressors can achieve flow rates up to 3,000 MSCFD at maximum working pressures up to 1,500 psig (103 bar).
