Naphtha (petroleum), light steam- cracked, hydrogenated; Low boiling point hydrogen treated naphtha; [A complex combination of hydro carbons produced from the separation and subsequent hydroge nation of the products of a steam- cracking process to produce ethylene. It consists predominantly of saturated and unsaturated paraffins, cyclic paraffins and cyclic aromatic hydrocarbons having carbon numbers predomi nantly in the range of C4 through C10 and boiling in the range of approximately 50 °C to 200 °C (122 °F to 392 °F). The proportion of benzene hydrocarbons may vary up to 30 wt. % and the stream may also contain small amounts of sulfur and oxygenated compounds.]
Hydrocarbons, C6-11, hydrotreated, dearomatized; Low boiling point hydrogen treated naphtha; [A complex combination of hydro carbons obtained as solvents which have been subjected to hydro treatment in order to convert aromatics to naphthenes by catalytic hydrogenation.]
Hydrocarbons, C9-12, hydrotreated, dearomatized; Low boiling point hydrogen treated naphtha; [A complex combination of hydro carbons obtained as solvents which have been subjected to hydro treatment in order to convert aromatics to naphthenes by catalytic hydrogenation.]
Natural gas condensates (petro leum); Low boiling point naphtha - unspecified; [A complex combination of hydro carbons separated as a liquid from natural gas in a surface separator by retrograde condensation. It consists mainly of hydrocarbons having carbon numbers predomi nantly in the range of C2 to C20. It is a liquid at atmospheric temperature and pressure.]
Naphtha (petroleum), light hydro cracked; Low boiling naphtha - unspecified; [A complex combination of hydro carbons from distillation of the products from a hydrocracking process. It consists predominantly of saturated hydrocarbons having carbon numbers predominantly in the range of C4 through C10, and boiling in the range of approxi mately – 20 °C to 180 °C (– 4 °F to 356 °F).]
Naphtha (petroleum), heavy hydro cracked; Low boiling point naphtha - unspecified; [A complex combination of hydro carbons from distillation of the products from a hydrocracking process. It consists predominantly of saturated hydrocarbons having carbon numbers predominantly in the range of C6 through C12, and boiling in the range of approxi mately 65 °C to 230 °C (148 °F to 446 °F).]
Naphtha (petroleum), sweetened; Low boiling point naphtha - unspecified; [A complex combination of hydro carbons obtained by subjecting a petroleum naphtha to a sweetening process to convert mercaptans or to remove acidic impurities. It consists of hydrocarbons having carbon numbers predominantly in the range of C4 through C12 and boiling in the range of approxi mately – 10 °C to 230 °C (14 °F to 446 °F).]
Naphtha (petroleum), acid-treated; Low boiling point naphtha - unspecified; [A complex combination of hydro carbons obtained as a raffinate from a sulfuric acid treating process. It consists of hydrocarbons having carbon numbers predominantly in the range of C7 through C12 and boiling in the range of approxi mately 90 °C to 230 °C (194 °F to 446 °F).]
Naphtha (petroleum), chemically neutralized heavy; Low boiling point naphtha - unspecified; [A complex combination of hydro carbons produced by a treating process to remove acidic materials. It consists of hydrocarbons having carbon numbers predominantly in the range of C6 through C12 and boiling in the range of approxi mately 65 °C to 230 °C (149 °F to 446 °F).]
Naphtha (petroleum), chemically neutralized light; Low boiling point naphtha - unspecified; [A complex combination of hydro carbons produced by a treating process to remove acidic materials. It consists of hydrocarbons having carbon numbers predominantly in the range of C4 through C11 and boiling in the range of approxi mately – 20 °C to 190 °C (– 4 °F to 374 °F).]
