Blackmer® Adds NG/NGS Series Reciprocating Gas Compressors as a Solution for Oilfield Applications

Grand Rapids, MI – Blackmer®, a global leader in positive displacement and centrifugal pump, and reciprocating compressor technologies, is pleased to announce the availability of the NG and NGS Series Reciprocating Gas Compressors. The NG and NGS Series compressors have been designed to optimize operational capabilities in a number of critical oilfield production and storage  applications, including wellhead annulus gashead pressure reduction, wellhead vapor control, pressure boosting, tank-battery vapor control and recovery, gas gathering, gas evacuation, gas blanketing, flare elimination, and enhanced oil and gas recovery.

The NG Series compressors, which are available in eight models—NG162, NG172, NG362, NG372, NG602, NG612, NG642 and NG942—are highly efficient and available in heavy-duty single- and two-stage configurations. Their advanced design technology and materials, which includes a standard double seal with single distance piece located between two sets of seals on each piston rod, provide maximum performance with minimum maintenance. This includes leakage control that prevents oil contamination of the compressed gas stream.

The NGS Series compressors have been designed for the handling of sour gas that may contain up to 8% dry hydrogen sulfide (H2S) and are also available in eight models—NGS162, NGS172, NGS362, NGS372, NGS602, NGS612, NGS642 and NGS942—and in single- or two-stage configurations with standard double seal. To enhance their compatibility with sour gas, the NGS compressors also feature select parts (that follow NACE guidelines) in all gas-containment areas and steel wrist pins that ride on steel needle bearings for extra life under severe operating conditions.

Both the NG and NGS Series compressors offer a ductile-iron head and cylinders, pressure-lubricated crankcases, air-cooled cylinders and O-ring gaskets throughout, that provide positive sealing under all operating conditions. The NG and NGS compressors can achieve flow rates from 10 to 600 MSCFD at maximum allowable working pressures to 615 psia (42.4 bara).
