Natural Gas Reciprocating Compressor Systems

Overview Natural gas is never a single specification. Wellhead gas, associated gas, wet gas, pipeline-quality gas and CNG each arrive with a different composition, water and heavy-hydrocarbon content, heating value and pressure – and the compressor has to be engineered around the gas that is actually...

Overview Hydrogen chloride and chlorine are the gases that punish anyone who tries to reuse a natural gas design. Both are strongly corrosive, and in the presence of even trace moisture the corrosion rate rises sharply. Dry chlorine is manageable with the right materials; wet chlorine attacks most common...

Overview This page covers carbon dioxide duty where the machine operates close to or inside the dense-phase region and where the thermodynamic model, not the mechanical hardware, is the hard part of the design. In dense-phase CO2 the density approaches that of a liquid while the fluid remains a single...

Overview A biogas compressor spends most of its life dealing with what is in the gas rather than with the gas itself. Raw biogas from anaerobic digestion or landfill is saturated with water, carries hydrogen sulphide, ammonia, siloxanes and particulates, and its composition drifts with feedstock, temperature...

Overview Oilfield associated gas is the most demanding feed a compressor can be given. Suction pressure is often barely above atmospheric and fluctuates constantly, the composition shifts as the field ages, and the gas arrives wet, with condensate, heavy hydrocarbons, traces of H2S and solid particles....

Overview Argon is a monatomic noble gas with a molecular weight close to that of air, but it is recovered and sold as a high-purity product, so the engineering priority is cleanliness and containment rather than reactivity. The gas is expensive, which makes leakage both a quality problem and a direct...

Overview This page covers reciprocating ammonia compressor packages in refrigeration and industrial process service, where the emphasis falls on continuous duty, oil management and safe handling. Ammonia refrigeration compressors run long hours at stable load, so reliability comes from conservative piston...

Overview TUKE ENERGY’s core business is process gas, not general-purpose shop air. This page covers the cases where a customer genuinely needs a reciprocating machine on air or on enriched-air duty: high-pressure industrial air where screw compressors cannot reach, compressed-air supply inside...
