MPLX operates several natural gas gathering systems with the scope of services provided dependent on the composition of the raw or untreated gas. Our natural gas processing complexes remove the heavier and more valuable hydrocarbon components from natural gas.

Once natural gas has been processed, the heavier and more valuable hydrocarbon components, which have been extracted as a mixed NGL stream, can be further separated into their component parts for end-use sale through the process of fractionation. We sell basic NGL products, including ethane, propane, normal butane, isobutane and natural gasoline.
