    Procedure for the selective extraction of viscous hydrocarbons remaining in storage tanks. The process is characterized by its heating operations, which make it possible to extract the hydrocarbons free of contaminants and not generate the risks of uncontrollable leaks from non-watertight funds associated with other processes. The heating is done as follows: - by means of devices immersed in the hydrocarbons and separated from the bottom of the tank, or by means of devices located outside the tank on the suction lines and contiguous zones of the tank envelope. - by injecting hot air into the tank, to fluidify the surface layer of hydrocarbons and to ventilate the tank and prevent the generation of explosive atmospheres. - through external heat exchangers, which facilitate filtering, decanting or subsequent transfers of hydrocarbons. The procedure is applicable to oil tanks, fuel oil and other viscous petroleum products, including tanks accidentally contaminated with water.
