Abstract
<PICT:0847199/III/1> <PICT:0847199/III/2> <PICT:0847199/III/3> A method of recovering oil from sludge in an oil tanker (see Group XXXIII) comprises passing the oil and/or sludge and water originating from oil-carrying tank washing operations to a separating tank 12 and allowing the mixture to spread over the surface of the fresh water that partially fills the tank. The temperature of the tank 12 is raised by heating coils to accelerate the separation of the oil. During the washing operations the clean water in the tank 12 is recycled for further tank-washing operations and, on completion of these operations, is discharged overboard. The oil residues, sediment and water remaining in the tank 12 are pumped to a sludge tank 13 and heat is applied to this tank for sufficient time to allow the remaining small quantity of water to separate and be drained off. The oil left in the tank 13 may be suitable fuel for the tanker's engines; if not it is pumped via a service tank 16 and a preheater 18 to a distilling plant situated on the tanker's deck. The service tank 16 has a sloping bottom to reduce the possibility of "slugs" of water being drawn into the distilling plant. The oil, water vapour and oil vapours pass into the distillation column 19, which comprises six equally-spaced and inclined trays a-f attached to a vertical shaft 27, and the vapour separated from the mixture passes out to amosphere through the upriser 22, any condensate collected being removed and disposed of. The liquid portion of the mixture passes down to the re-boiler 20, which is heated by a steam coil 23 and a steam pipe 24, and further evaporation takes place. The oil in the re-boiler 20 is kept at a constant level by an outlet valve 26 controlled by a float 25. The mixture is passed back to the tank 16 and recirculated until it has the required flash point. It is then directed to a fuel storage tank from whence it can be drawn for use in the tanker's engines. Specification 743,713 is referred to.
