    Abstract: A tanker (I) is washed with high pressure water (1) with the effluent liquid passing to storage/disposal (II), and any displaced vapors being pumped away by a pump (III) via a water disentrainment device (IV) and fed into a combustion chamber (V) from where combustion products are cooled through a heat recovery unit (VI) before being washed with alkaline solution in a scrubber (VII) and discharged to the atmosphere via a stack (VIII). A tanker (I), in a cleaning station, is washed with high pressure water (1), optionally containing detergents, with the effluent liquid passing to storage/disposal (II), and any displaced vapors, etc. being pumped away by a pump (III) via a water disentrainment device (IV) and fed into a combustion chamber (V) maintained at 800-1200 deg C. The combustion products from the furnace (V) are cooled through a heat recovery unit (VI) before being washed with alkaline solution in a scrubber (VII) and discharged to atmosphere via a stack (VIII). The vapor pump may be a liquid ring pump or a fan, etc.

    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.
