Gas condensates — the raw material for the production of diesel fuel

Gas condensates are liquid hydrocarbons condense under normal conditions and natural gas in underground formations pressure 4,9-9,8 MPa and a temperature of 1500.Gas condensate fields in Russia are very diverse. There is, for example, condensates, consisting almost entirely of petroleum fractions (Orenburg, Kanchurinsko field Fililovskaya deposit, etc.), containing, along with gasoline, diesel fuel fractions (Urengoiskoye, Zapolarnoye, Nain deposits, etc.) containing oil (above 350 ° C, Shatlykskoe, Vuktylskoye, Russian countryside, etc.) containing oil fractions (above 400 ° C, Russian countryside, Dauletabadskoe).

Gas condensates in comparison with light oil fractions have a peculiar composition, for example, by distillation to separate condensate desyatigradusny percentage of distillate fractions with increasing boiling point significantly increased, reaching a maximum at 80-130 ° C, after which the value of its sharply at first and then more slowly decreases.

Typically, most of the condensate is distilled at temperatures up to 200 ° C. Apparently, this was the reason for the development of SDT with significantly facilitated fractional composition. However, despite the significant amount of light ends gas liquids are almost always the residue with a wide fractional composition. The choice of the direction of gas condensate processing, along with the fractional composition, strongly influenced by the composition of the hydrocarbon group.
