Well, doesn’t all of the gas get to where it’s going?
No. Compressor stations are built along the pipeline consuming a portion of the Gas as fuel to keep pushing it along and overcoming the constant pressure drop created by friction.
Gas and Liquid pipelines have losses due to friction. They require some other form energy to overcome those losses. You either burn the fuel in the pipeline, or consume some other source of energy to drive pumps or compressors.
The total pipeline is miles 1,407 miles long.
It has 18 Compressor Stations.
The total installed Horsepower of those stations equals 517,000.
It can carry up to 2,400 million cubic feet per day. This is a very large pipeline.
Some of these stations are compressors as large as 42,000 Hp aircraft derivative jet engines. Other are smaller 10~15,000 Hp Electric driven variable speed drives.
