A natural-gas processing plant in Aderklaa, Austria. Natural-gas processing is a range of industrial processes designed to purify raw natural gas by removing contaminants such as solids, water, carbon dioxide (CO 2), hydrogen sulfide (H 2 S), mercury and higher molecular mass hydrocarbons to produce pipeline quality dry natural gas [1] for pipeline distribution and final use.

Fractional distillation is the most common form of separation technology used in petroleum refineries, petrochemical and chemical plants, natural gas processing and cryogenic air separation plants. [ 3 ] [ 4 ] In most cases, the distillation is operated at a continuous steady state .
Fractionation is widely employed in many branches of science and technology. Mixtures of liquids and gasses are separated by fractional distillation by difference in boiling point. Fractionation of components also takes place in column chromatography by a difference in affinity between stationary phase and the mobile phase .
The gas is next compressed and enters a 'cold box' comprising a further series of heat exchangers which chill the gas until it is liquefied. [8] The liquid passes into a series of three tall fractionation towers and a reactor. In the first tower, the de-methaniser, hydrogen and methane are removed from the top and are used as fuel gas in the plant.
[1] [2] Fractionating columns are widely used in chemical process industries where large quantities of liquids have to be distilled. [3] [4] [5] Such industries are petroleum processing, petrochemical production, natural gas processing, coal tar processing, brewing, liquefied air separation, and hydrocarbon solvents production.

As the Turner Valley story illustrates, the extraction of natural gas liquids goes back to the industry's early years. However, the development of partnerships between the large American oil company Amoco and the young, dynamic Dome Petroleum to create sophisticated liquids infrastructure in Western Canada.
