Blackmer's NG Series natural gas vapour recovery compressor.

The NG Series comprises single-stage, oil-free reciprocating gas compressor that can be used in oi and gas production in the areas of tank-battery vapour recovery, wellhead vapour control, wellhead annulus reduction and pressure boosting.

Blackmer's compressers featurea full compartment distance piece as standard on all NG models. Each NG compressor is constructed with two sets of piston rod seals between the crosshead guide and cylinder area, which form the distance piece. The distance piece provides leakage control and helps prevent oil contamination from any condensates that might be in the gas stream. Connections are provided in the distance-piece for purging, pressurizing or venting as needed. This design also allows the NG compressors to handle a much wider range of suction pressures, which can be a major consideration in wellhead operations that involve natural gas and methane mixes.

The NG Series compressors also feature a ductile-iron head and cylinder, o-ring gaskets throughout, flow rates to 600 MSCFD, a maximum of 50-horsepower energy usage and a maximum allowable working pressure of 350 psia (24.1 bara).
