Effect of Inhibitor Additives on the Composition of Paraffin Deposits of Gas Condensate from the Urengoy Field

Institute of Petroleum Chemistry, Siberian Branch of the Russian Academy of Sciences, Prospekt Akademicheskiy 4, Tomsk 634021(Russia)
Keywords: has condensate, paraffin deposits, inhibitor additive, paraffin hydrocarbons, aromatic hydrocarbons


The effect of inhibitor additives of different chemical nature on the composition of paraffin deposits of gas condensate at the Urengoy field was determined. It was established that the most efficient additives are those based on polyalkylmetacrylates. The use of highly efficient additives leads to concentrating high-molecular paraffin hydrocarbons and to a decrease in the fraction of naphthene aromatic hydrocarbons in the deposits.
