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.

Fractionation is a separation process in which a certain quantity of a mixture (of gasses, solids, liquids, enzymes, or isotopes, or a suspension) is divided during a phase transition, into a number of smaller quantities in which the composition varies according to a gradient.
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 .
Amine gas treater, Claus unit, and tail gas treatment for converting hydrogen sulfide gas from the hydrotreaters into end-product elemental sulfur. The large majority of the 64,000,000 metric tons of sulfur produced worldwide in 2005 was byproduct sulfur from petroleum refining and natural gas processing plants. [8] [9]
This process is the origin of the name fractional distillation or fractionation. Distillation is one of the most common and energy-intensive separation processes. Effectiveness of separation is dependent upon the height and diameter of the column, the ratio of the column's height to diameter, and the material that comprises the distillation ...
At the Fife NGL plant natural gas liquid is separated into its component parts by distillation in three sequential fractionation columns. These comprise a de-ethaniser, a de-propaniser and a de-butaniser, the constituent components and products from the plant are: ethane (C 2 H 6 ), propane (C 3 H 8 ), butane (C 4 H 10 ) and pentane (C 5 H 12 ...
A separation process is a method that converts a mixture or a solution of chemical substances into two or more distinct product mixtures, [1] a scientific process of separating two or more substances in order to obtain purity. At least one product mixture from the separation is enriched in one or more of the source mixture's constituents.
Natural gas liquids (NGL) are the fraction of the hydrocarbons, primarily having 2-8 carbon atoms, [4] that are present in the flash gas during oil production or as liquids in natural gas production. In other words, NGL is the liquids removed from natural gas such as ethane and heavier products. [5]
