Coal liquids, liquid solvent extraction solution.; (The product obtained by filtration of coal mineral matter and undis solved coal from coal extract solution produced by digesting coal in a liquid solvent. A black, viscous, highly complex liquid combination composed primarily of aromatic and partly hydro genated aromatic hydrocarbons, aromatic nitrogen compounds, aromatic sulfur compounds, phenolic and other aromatic oxygen compounds and their alkyl derivatives.)
Coal liquids, liquid solvent extraction; (The substantially solvent-free product obtained by the distillation of the solvent from filtered coal extract solution produced by digesting coal in a liquid solvent. A black semi-solid, composed primarily of a complex combination of condensed-ring aromatic hydrocarbons, aromatic nitrogen compounds, aromatic sulfur compounds, phenolic compounds and other aromatic oxygen compounds, and their alkyl derivatives.)
Light oil (coal), coke-oven; Crude benzole (The volatile organic liquid extracted from the gas evolved in the high temperature (greater than 700 °C) destructive distillation of coal. Composed primarily of benzene, toluene, and xylenes. May contain other minor hydro carbon constituents.)
Distillates (coal), liquid solvent extraction, primary; (The liquid product of conden sation of vapours emitted during the digestion of coal in a liquid solvent and boiling in the range of approximately 30 to 300 °C. Composed primarily of partly hydrogenated condensed-ring aromatic hydrocarbons, aromatic compounds containing nitrogen, oxygen and sulfur, and their alkyl derivatives having carbon numbers predominantly in the range of C4 through C14.)
Light oil (coal), semi-coking process; Fresh oil (The volatile organic liquid condensed from the gas evolved in the low temperature (less than 700 °C) destructive distillation of coal. Composed primarily of C6-10 hydrocarbons.)
Residues (petroleum), atm. tower; Heavy fuel oil (A complex residuum from the atmospheric distillation of crude oil. It consists of hydrocarbons having carbon numbers predomi nantly greater than C20 and boiling above approximately 350 °C. This stream is likely to contain 5 wt % or more of four- to six-membered condensed ring aromatic hydrocarbons.)
Clarified oils (petroleum), catalytic cracked; Heavy fuel oil (A complex combination of hydro carbons produced as the residual fraction from distillation of the products from a catalytic cracking process. It consists of hydro carbons having carbon numbers predominantly greater than C20 and boiling above approximately 350 °C. This stream is likely to contain 5 wt % or more of four- to six-membered condensed ring aromatic hydrocarbons.)
Residues (petroleum), hydro cracked; Heavy fuel oil (A complex combination of hydro carbons produced as the residual fraction from distillation of the products of a hydrocracking process. It consists of hydro carbons having carbon numbers predominantly greater than C20 and boiling above approximately 350 °C.)
Residues (petroleum), thermal cracked; Heavy fuel oil (A complex combination of hydro carbons produced as the residual fraction from distillation of the product from a thermal cracking process. It consists predominantly of unsaturated hydrocarbons having carbon numbers predomi nantly greater than C20 and boiling above approximately 350 °C. This stream is likely to contain 5 wt % or more of 4- to 6-membered condensed ring aromatic hydrocarbons.)
Residues (petroleum) hydrodesul phurised atmospheric tower; Heavy fuel oil (A complex combination of hydro carbons obtained by treating an atmospheric tower residuum with hydrogen in the presence of a catalyst under conditions primarily to remove organic sulfur compounds. It consists of hydrocarbons having carbon numbers predominantly greater than C20 and boiling above approximately 350 °C. This stream is likely to contain 5 wt % or more of four- to six- membered condensed ring aromatic hydrocarbons.)
