Natural gas is rising to the surface due to its natural tendency to fill areas with the lowest pressure. Since gas produced from a well contains many admixtures, it is first taken for treatment. Comprehensive gas treatment units are built not far from certain fields; in some cases, gas is instantly taken to a gas processing plant.
A unique feature of propane is that it is not produced for its. own sake, but is a by-product of two other processes, natu-. ral gas processing and petroleum reï¬ ning. Figure 1 shows. a diagram of where propane comes from and how it gets to. the consumer. Natural gas plant production of propane primarily involves. extracting materials such as propane and butane from natu-. ral gas to prevent these liquids from condensing and caus-. ing operational problems in natural gas pipelines.
