    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.
