Does natural gas travel through pipelines?
Processing natural gas for transportation by pipeline Natural gas typically moves from natural gas and oil wells through a gathering system of pipelines to natural gas processing plants for treatment.
How deep is a natural gas pipeline buried?
Federal regulations require that transmission pipelines and regulated type A gathering lines be buried at least 30 inches below the surface in rural areas and deeper (36 inches) in more populated areas.
What impurities is removed during natural gas production?
Removal of all or most impurities is required before entering the pipeline. Although natural gas processing has several steps, the main processes include separation, carbon dioxide and hydrogen sulfide removal, dehydration, and NGL recovery.
How does the natural gas pipeline system work?
Natural gas is sourced from a producing well or field, and then sent through three main natural gas pipeline types: Gathering pipelines are small-diameter pipelines that move natural gas from a wellhead, to either a mainline transmission grid, or processing plant, depending on the quality of the initial product.
How does oil move through the pipeline system?
Product is gathered from wells in the ground and sent through gathering pipelines to a facility where it’s processed or refined. Pumps or compressors move it through the system at a safe pace. Once the oil is refined or the gas is processed, it’s moved through feeder pipelines to be distributed to large transmission pipelines.
How is natural gas transported across the country?
As can be seen, the pipeline network extends across the entire country. Interstate pipelines are the ‘highways’ of natural gas transmission. Natural gas that is transported through interstate pipelines travels at high pressure in the pipeline, at pressures anywhere from 200 to 1500 pounds per square inch (psi).
How are interstate natural gas pipelines different from intrastate pipelines?
Intrastate pipelines, on the other hand, transport natural gas within a particular state. This section will cover only the fundamentals of interstate natural gas pipelines, however the technical and operational details discussed are essentially the same for intrastate pipelines. Interstate Natural Gas Pipelines Interstate Natural Gas Pipelines
How does natural gas move through a pipeline?
Natural gas is moved through pipelines as a result of a series of compressors creating pressure differen- tials – the gas flows from an area of high pressure to an area of relatively lower pressure. Compressors are powered by electric or natural gas fired engines that compress or squeeze incoming gas and push it out at a higher pressure.

How does a natural gas transmission line work?
Compressors are powered by electric or natural gas-fired engines that compress or squeeze incoming gas and push it out at a higher pressure. As one would expect compressor stations for large transmission lines are much bigger than the compressors used to move the gas through the small distribution lines to our homes.
What are the different types of natural gas pipelines?
There are three major types of pipelines along the transportation route: the gathering system, the interstate pipeline system, and the distribution system. The gathering system consists of low pressure, small diameter pipelines that transport raw natural gas from the wellhead to the processing plant.
