    Abstract: Process for flaring off the let-down gases from reactors of a liquid-phase hydrogenation of coal or heavy oil, the reaction product leaving the reactors in vapour form together with unreacted hydrogen and gaseous C1-C4 hydrocarbons formed, this stream being cooled and the hydrocarbons condensing out, and the hydrocarbon condensate of the gases being separated in a cold separator, the pressurised gases leaving the cold separator being used as a propellant gas medium for the intake of combustion air for the flaring of the let-down gases.
