In highly developed countries. ready and abundant supplies of energy — for heat, electricity and fuel — are essential to the conduct of commerce and quality of life. This is why expansive infrastructure networks spread across the United States and other economically advanced nation-states. These chains consist of extraction sites, pipelines, refineries, processing facilities and storage repositories. Conveying natural gas and biogas, for instance, through these systems at a reasonable tempo and in sufficient quantity requires reducing the volume under normal atmospheric conditions. Key to this task is the employment of a gas compressor at various points in the supply chain.

What Is a Compressor?

A compressor is an instrument that condenses natural gas so that its volume is constricted to a fraction of what it was pre-compression, i.e. under standard atmospheric pressure. It crunches the gas molecules so they occupy less space. At the same time, the number of molecules remains constant. Just as suitcase contents can be re-arranged to fit more in by eliminating space between articles, gas compression puts molecules closer together so more gas can fit in pipelines and storage tanks. This procedure applies the Ideal Gas Law — pressure x volume = number of moles x universal gas constant x temperature. In short, increasing pressure reduces volume.

What Are Compressors Used For?

Compressors have a wide variety of applications. Among their many functions:

  • They compress air for pneumatically powered hand tools like staple guns, nail guns, sanders, riveters, jack hammers and drills.
  • They compress gases like hydrogen and oxygen for chemical processing.
  • They compress light hydrocarbon fractions in oil refineries.
  • They compress natural gas for transport and storage.

It is this last use that bears special attention. This is where heavy duty compression is called for and one specific kind is commonly employed.

Compressors Based on Reciprocity

Among the classes of compressors are those known as intermittent flow. Also known as positive displacement compressors, they process gas in units as opposed to one continuous flow. This category consists of the rotary and reciprocating compressors. Perhaps the major difference between the two is that the former use rotors whereas the latter use pistons. They are similar in that they do their work in the manner of a lung — gas in, compressed gas out; rinse and repeat. The piston variety, or reciprocating compressor, is a critical component of most natural gas operations.

How Does a Reciprocating Piston Compressor Work?

Essentially, most types of reciprocating compressor consist of compression cylinders — sometimes called stages — that detain the gas during the process. In addition, the piston is there to do the actual task of compression. It should be noted that gas is compressed on one side of the piston unless it is part of a double acting reciprocating compressor, in which case the piston works on both sides of its stroke. Variations on this design might include two pistons. Reciprocating compressor manufacturers can vary the design in other ways, too.

For example, it is understandable that any machine with pistons moving back and forth for long periods will require lubrication. Many models incorporate a force-feed lubrication system with oil as the lubricant. However, some jobs are sensitive to oil splash or dispersion so there are also oil free reciprocating air compressors. Here the inner surfaces of the cylinders are pre-coated with alternative lubricating agents. One advantage with oil free is that there is no adding or changing to be remembered or performed. On the other hand, oil-lubed machines tend to have greater longevity so selecting one over the other always involves a trade-off

Other Modifications

Compression can be applied to any number of gases for myriad jobs and tasks. Cylinders are manufactured in different sizes and capacities. Beyond these variations, the number of cylinders is not fixed in either reciprocating air compressors or reciprocating gas compressors. Between the valve where air or gas is received, and the nozzle through which it is expelled, are the cylinders where compression takes place. In a single stage reciprocating air compressor, the air is compressed by a single stroke of the piston exerting pressure of 120 pounds per square inch (psi), and then flows to the storage tank. By contrast, a two stage reciprocating air compressor encompasses a second cylinder where the air is further compressed to 175 psi before storage.

Multistage reciprocating compressors provide more capacity and efficiency. They can power more tools and require no more maintenance than single- or dual-stage compressors. They subject the gas to additional cycles of compression, heating and cooling. Other compressor alterations conern the matter of alignment. A vertical air compressor consumes less floor space than a horizontal air compressor. At the same time, the horizontal compressor might fit better than the v air compressor in the work space. If the compressor is horizontally aligned — or the compressor vertical — both function exactly alike.

In Summary

Gas and air compression machines that operate with reciprocating pistons are relied upon for large tasks that require more power. They come in variable designs and arrangements, each contingent on work environment and how much power is needed for a given undertaking. When more pressure is necessary, they do the job.
