What is "Pipeline Compression"?

Pipeline compression takes place along natural gas pipelines and at "compressor stations" where the natural gas compressors are located.  

If compressor stations act as the "brain" for natural gas pipelines then natural gas compressors serve as the heart for natural gas pipelines.  Compression of natural gas is required to "transport" or move the natural gas from the upstream oil and gas, and midstream oil and gas sectors - to the downstream oil and gas markets where the natural gas is sold to residential, commercial and industrial customers.

Where field compression normally requires low-to-medium-range (gas compressor) horsepower, relatively low pressures and is located at or near the wellhead, pipeline compression, on the other hand, requires high horsepower, high pressures, and may be hundreds of miles away from where the natural gas is first injected into the pipeline.

What are Axial Compressors?

Axial Compressors are high efficiency, high-reliability compressors used in high volume applications, including;

• air separation

• Compressed Air Energy Storage - CAES

• sewage treatment

• wind tunnels

Axial Compressors' pressure ratios are determined by the number of stages in each axial compressor and the and volume or gas flow can be varied by changing the length of the blades

Axial Compressors are ideally suited for applications requiring high flow and low compression ratios.

What is Electric Compression?

Electric compression uses electric motors to run gas compressors.  This may seem to be illogical if you are in the natural gas business, to use electricity to drive your gas compressors. However, there are circumstances and locations that make electric compression a serious consideration.

One of the key benefits to electric compression is the fact that there is no combustion, therefore, there are no emissions - because there is exhaust AT THE LOCATION OF THE ELECTRIC COMPRESSOR.  Note that there ARE emissions related to electric compression, but these emissions are generated at the electric power plant that generates the electricity for the electric compressor(s). Electric compression , like typical gas compression systems, requires cooling of the gas through the heat exchanger(s).

Drawbacks for considering electric compression are;

• the resulting monthly power/electric bills 

• limitations of the power supply/source

• installation costs

What is "Field Compression"?

Field compression takes place in the "gas gathering" process of natural gas production which is also referred to as the "midstream oil and gas" sector.  This is also the area that gas processing and natural gas treatment occurs to make the natural gas "pipeline quality gas." 

Compression of natural gas is required to "transport" or move the natural gas from the wellhead - where the natural gas arrives at the surface - through the gas gathering system - and then sold and injected into a natural gas pipeline, where "pipeline compression" of the natural gas is required thereafter.

Field compression is also used in the reinjection of the natural gas back into oil and natural gas reservoirs to maintain reservoir pressure as well as to provide "gas lift" of the reservoir's liquids to the surface.

Field compression normally requires low- to medium-range gas compressor horsepower that is located at or near the wellhead.

Compression equipment is also used to increase the efficiency of a low capacity gas field by providing a central compression point from which the gas can be produced and injected into a pipeline for transmission to facilities for further processing.  Because field compression and gas compression is a necessary and added expense, owners and operators of gas gathering systems attempt to keep the pressure of the gas gathering system as low as possible. 

Natural Gas Compressors are mechanical devices that increase the pressure of the (natural) gas by reducing its volume.

What is "Fuel Gas Compression"?

Fuel gas compression is the process of increasing the pressure of the "fuel gas" to the inlet of gas turbine fueled genset (power plant) through a "fuel gas compressor" - also referred to as a "fuel gas booster."

Natural gas fired turbines used in power plants are typically fueled by natural gas - the natural gas inlet pressure may be as low as 30 psig in the city limits or as 250 psig outside of the city gate.  Gas turbine power plants normally require an "inlet" pressure to the gas turbine any where from 250 psig to as much as 600 psig.  Due to the natural gas pipeline pressure operating under the minimum inlet fuel pressure requirement, fuel gas compressors are needed to increase the fuel pressure to the gas turbine(s).

Gas compressors are mechanical devices that increase the pressure of the (natural) gas by reducing its volume.
