The natural gas transportation system is depicted in this Natural gas pipeline system process flow. Compressor stations, pipelines, city gate stations, and storage facilities comprise a natural gas transportation system. The compressor station is the transmission system's beating heart, supplying the energy needed to keep the gas flowing at the specified flow rate and pressure. Onshore and offshore pipelines are classified into trunk or gathering pipelines, transmission pipelines, and transportation and distribution pipelines. The natural gas pipeline system process flow depicts the various types of channels based on their function. Natural gas pipelines are primarily used to transport gas from the field to consumers.
