"Natural gas is highly pressurized as it travels through an interstate pipeline. 
To ensure that the natural gas flowing through any one pipeline remains 
pressurized, compression of this natural gas is required periodically along the pipe. 
This is accomplished by compressor stations, usually placed at 
40 to 100 mile intervals along the pipeline. The natural gas enters the compressor station, where it is compressed by either a turbine, motor, or engine.

Turbine compressors gain their energy by using up a small proportion 
of the natural gas that they compress. The turbine itself serves to operate 
a centrifugal compressor, which contains a type of fan that compresses 
and pumps the natural gas through the pipeline. 

Some compressor stations are operated by using an electric motor 
to turn the same type of centrifugal compressor. This type of compression 
does not require the use of any of the natural gas from the pipe, 
however it does require a reliable source of electricity nearby. 

Reciprocating natural gas engines are also used to power some compressor stations. 
These engines resemble a very large automobile engine, 
and are powered by natural gas from the pipeline. 
The combustion of the natural gas powers pistons on the outside of the engine, 
which serves to compress the natural gas.

  1. Very informative blog. Here I found valuable information on natural gas facts and compressor station. Thanks
