Skid Mounted systems for Gas Compression

September 25, 2014

A gas compression infrastructure typically includes a compressor and a series of components designed to remove particulate matter from the gas as it's transmitted through a network of pipes. The compressor sits at the heart of the fabricated system of parts, reducing the volume of the gas for storage, or passing the pressurized mass onto a secondary stage for further processing. Without labeling any particular industry just yet, the pressurized gas is reduced into a dense state, still gaseous, or further condensed into a liquid form. The advent of modular engineering aids in assigning the correct configuration of gas compression to an engineering application, and it's the maturation of skid technology that's simplifying this approach.

The reduced footprint of a skid-mounted assembly places all of the components of a working system on one steel base plate, a robust common bundle of mechanical drivers, auxiliary parts, pipes and input/output stages complete with filtration. Generally speaking, the manufacturing process is conducted at the fabrication shop, using blueprints to weld every pipe, vessel, and platform in place. The skid is also outfitted with electrical fit-out wiring, compartments, and instrumentation. The inclusion of the fit-out makes it a breeze to hook up one or more electrical motors to the compressor shaft, and the only task left is to decide on the configuration of the central compressor, to opt for a reciprocal or rotary cycle of compression.

The viability of a modular gas compression skid lays in ease of construction, in the ability to lever superior quality control at the fabrication yard. The standard workflow pieces the structure together, adding platforms and accessibility features, before integrating the skid within its working environment. Engineering specifications will vary depending on an application, but a gas scrubber is a consistent part of the fabricated structure, an in-line component that removes suspended water droplets and fine particles. If the processed substance in question is natural gas, further filtration stages are introduced to clean the raw material of pollutants, intrusive substances, including water, carbon dioxide, and the noxious sulfides that have combined with the gas deep below the ground.

The assemblage of pipes and vessels welded and bolted to a skid-mounted gas compression system act as a processing stage, cleaning the gas, reducing its volume, all in preparation for storage or distribution through a network of pipes. In accordance with design specifications, the vessels and auxiliary components are rated for the operating pressure as set by the compression sub-assembly, but there are other applications worthy of note for these hardy structures. A gas compression system fits in immediately in oil refineries and offshore platforms, but they're also intrinsic parts of more dynamic systems. Biofuels are condensed for storage and transport by the skid-mounted assemblies, as is the gas destined for ignition in power stations. The gas turbines, industrial boiler fuel systems, furnaces and steel fabrication facilities, all require the modular versatility of a gas compression system as mounted on a precisely configured steel base plate, a compact skid.
