ABSTRACT:
A method for the internal cleaning of a tank. An oil sump and a gas mixture which is diffused out of the oil sump and has a hydrocarbon-containing gas being present in the crude-oil tank. The gas mixture is sucked away out of the tank and a feed of an inert gas into the tank is permitted. An energy content of the sucked-away gas mixture is determined. The gas mixture is fed to a compressor for compressing the gas mixture, if the energy content of the gas mixture overshoots a limit value, in order to compress the gas mixture in the compressor. The gas mixture is fed to a consumer unit, if the energy content of the gas mixture undershoots the limit value.
