We Produce, Transport & Market Natural Gas Liquids

Raw natural gas is usually found in deep underground reservoirs formed by porous rock.

It is a naturally occurring mixture of hydrocarbon gases including methane, ethane, propane, butane and pentane; non-hydrocarbon gases including water vapor, hydrogen sulfide, carbon dioxide, helium and nitrogen; and other compounds. 

Gas processing takes raw natural gas and removes the various hydrocarbons, non-hydrocarbons and other compounds to produce natural gas – primarily composed of methane – that meets pipeline quality specifications.

During processing, the hydrocarbons ethane, propane, butane and pentane are separated from the raw gas and recovered, through condensation or absorption, as natural gas liquids (NGLs). These hydrocarbons are further divided into distinct products during a process called fractionation.

NGLs – ethane, propane, butane and pentane – are valuable by-products with a variety of uses including as sources of energy and raw materials. Regional propane distributors as well as petrochemical and oil refining companies utilize NGLs.

DCP Midstream produces, fractionates, transports, trades and markets natural gas liquids (NGLs). In fact, DCP Midstream is the largest producer of natural gas liquids and the largest natural gas processor in the U. S. DCP Midstream is a 50-50 joint venture between Spectra Energy and Phillips 66.
