METHOD OF PREVENTING FOULING OF HOT SEPARATOR IN HYDROCONVERSION OF HEAVY HYDROCARBON OILS Abstract of the Disclosure The operation of a hydrocracking process to recover valuable liquid hydrocarbons from heavy hydro- carbon oils, such as heavy bituminous oil extracted from tar sands, is significantly improved when the downstream liquid-gas separator is operated at the pressure of the hydrocracking stage and the effluent from the hydro- cracking stage is introduced into the liquid-gas separator below the liquid level in the separator. This reduces settling of mineral matter contained in the effluent, prevents phase separation of the hydrocarbon liquid in the separator, reduces hydrogen starvation thereby preventing polymerization and coking of the hydrocarbon liquid in the separator and substantially eliminates sludge formation in the separator and plugging of the liquid outlet.
