Extracts (petroleum), heavy naph thenic distillate solvent, hydro treated; Distillate aromatic extract (treated) (A complex combination of hydro carbons obtained by treating a heavy naphthenic distillate solvent extract with hydrogen in the presence of a catalyst. It consists predominantly of aromatic hydro carbons having carbon numbers predominantly in the range of C20 through C50 and produces a finished oil of at least 19 10-6 m2.s-1 at 40 °C.)
Extracts (petroleum), hydrotreated paraffinic light distillate solvent; Distillate aromatic extract (treated) (A complex combination of hydro carbons obtained as the extract from solvent extraction of inter mediate paraffinic top solvent distillate that is treated with hydrogen in the presence of a catalyst. It consists predominantly of aromatic hydrocarbons having carbon numbers predominantly in the range of C16 through C36.)
Extracts (petroleum), light naph thenic distillate solvent, hydrode sulphurised; Distillate aromatic extract (treated) (A complex combination of hydro carbons obtained by treating the extract, obtained from a solvent extraction process, with hydrogen in the presence of a catalyst under conditions primarily to remove sulphur compounds. It consists predominantly of aromatic hydrocarbons having carbon numbers predominantly in the range of C15 through C30. This stream is likely to contain 5 % wt or more of four- to six- membered condensed ring aromatic hydrocarbons.)
Extracts (petroleum), light paraffinic distillate solvent, acid- treated; Distillate aromatic extract (treated) (A complex combination of hydro carbons obtained as a fraction of the distillation of an extract from the solvent extraction of light paraffinic top petroleum distillates that is subjected to a sulphuric acid refining. It consists predominantly of aromatic hydrocarbons having carbon numbers predominantly in the range of C16 through C32.)
Extracts (petroleum), light paraffinic distillate solvent, hydrodesulphurised; Distillate aromatic extract (treated) (A complex combination of hydro carbons obtained by solvent extraction of a light paraffin distillate and treated with hydrogen to convert the organic sulphur to hydrogen sulphide which is eliminated. It consists predominantly of hydrocarbons having carbon numbers predomi nantly in the range of C15 through C40 and produces a finished oil having a viscosity of greater than 10-5 m2.s-1 at 40 °C.)
Extracts (petroleum), light vacuum gas oil solvent, hydrotreated; Distillate aromatic extract (treated) (A complex combination of hydro carbons obtained by solvent extraction from light vacuum petroleum gas oils and treated with hydrogen in the presence of a catalyst. It consists predomi nantly of aromatic hydrocarbons having carbon numbers predomi nantly in the range of C13 through C30.)
Extracts (petroleum), heavy paraffinic distillate solvent, clay- treated; Distillate aromatic extract (treated) (A complex combination of hydro carbons resulting from treatment of a petroleum fraction with natural or modified clay in either a contact or percolation process to remove the trace amounts of polar compounds and impurities present. It consists predominantly of aromatic hydrocarbons having carbon numbers predominantly in the range of C20 through C50. This stream is likely to contain 5 % wt or more four- to six- membered ring aromatic hydrocar bons.)
Extracts (petroleum), heavy naph thenic distillate solvent, hydrode sulphurised; Distillate aromatic extract (treated) (A complex combination of hydro carbons obtained from a petroleum stock by treating with hydrogen to convert organic sulphur to hydrogen sulphide which is removed. It consists predominantly of aromatic hydrocarbons having carbon numbers predominantly in the range of C15 through C50 and produces a finished oil with a viscosity of greater than 19 10-6 m2.s-1 at 40 °C.)
Extracts (petroleum), solvent- dewaxed heavy paraffinic distillate solvent, hydrodesulphurised; Distillate aromatic extract (treated) (A complex combination of hydro carbons obtained from a solvent dewaxed petroleum stock by treating with hydrogen to convert organic sulphur to hydrogen sulphide which is removed. It consists predominantly of hydro carbons having carbon numbers predominantly in the range of C15 through C50 and produces a finished oil with a viscosity of greater than 19 10-6 m2.s-1 at 40 °C.)
Extracts (petroleum), light paraffinic distillate solvent, carbon-treated; Distillate aromatic extract (treated) (A complex combination of hydro carbons obtained as a fraction from distillation of an extract recovered by solvent extraction of light paraffinic top petroleum distillate treated with activated charcoal to remove traces of polar constituents and impurities. It consists predomi nantly of aromatic hydrocarbons having carbon numbers predomi nantly in the range of C16 through C32.)
