Apache Companies just bought this new D6 Bulldozer for a new pipeline compressor station job in west Texas for one of our oil and gas construction customers. Our main scope of work will be grading and stone layout for the compressor station just south of Midland, Tx.  

Compressor Stations: What They Do, How They Work, and Why They Are Important

One of the most important components of the natural gas transport system is the compressor station. These stations perform the essential task of compressing natural gas as it travels through pipelines. It is this compression which allows the gas to continue flowing through the pipe and eventually to its final destination for distribution to refineries and other end users.

What Are Compressor Stations?Natural gas pipeline compressor stations

Compressor stations are facilities located along a natural gas pipeline which compress the gas to a specified pressure, thereby allowing it to continue traveling along the pipeline to the intended recipient.

Frequency of Compressor Stations – The total number of compressor station facilities required to move product varies depending on the region and conditions. Generally compressor stations are located about every 40-70 miles along the pipeline.

Operating Pressure of the Pipeline – There is a wide variation in the pressure within a given section of pipeline compared to other pipelines in other areas. The typical pressure may range anywhere from 200 psi (pounds per square inch) to 1,500 psi. This wide variation is also due to the type of area in which the pipeline is operating, its elevation, and the diameter of the pipeline. Because of the change in the environment, compressor stations may compress natural gas at different levels. Supply and demand can also be a factor at times in the level of compression required for the flow of the natural gas.

Liquid Separation and Filtering at Compressor Stations – Compressor stations typically include scrubbers, strainers or filter separators which remove liquids, dirt, particles, and other impurities from the natural gas. Though natural gas is considered “dry” as it passes through the pipeline, water and other hydrocarbons may condense out of the gas as it travels. Thus compressor stations will also remove these impurities from the gas so that they can be disposed of or sold as desired.

Personnel at Compressor Stations – Depending on the particular compressor station, its size, sophistication (Automation), and other factors, it may or may not be staffed with live, on-site personnel. Many modern compressor stations can be completely monitored and operated remotely.

Compressor stations enable the natural gas itself to travel through the pipelines which is crucial to the natural gas transport system. They also allow the gas to be rerouted into storage areas during periods of low demand. In addition, compressor stations are often accompanied by PIG launchers and PIG receivers which are vital for the maintenance and efficiency of the pipeline. They even include many safety features allowing the pipeline and station to function safely.
