Abstract Tars and hydrocarbon oils containing water are dehydrated in a ther- mally efficient and environmentally acceptable manner. The tars or hydrocarbon oils are heated externally to and holding vessel to a temperature equivalent to at least 100°C. at atmospheric pressure and are sprayed into a holding vessel to enhance the separation of water from the tars or hydrocarbon oils. Then the water in the vapor state is removed from the holding vessel and scrubbed to remove any noxious chemicals. The apparatus for dehydrating tars or hydrocarbon oils consists of heating means, spraying means, an enclosed member, and scrubbing means. The healing means has an inlet for communication with a source of tars or hydro- carbon oils which is situated externally to the heating means or any vessel containing the heating means. The heating means has the capacity of heating the tars or hydrocarbon oils to a temperature equivalent to at least 100°C. at atmospheric pressure. The heating means has a discharge end in communication with a spraying means that sprays the heated tars or hydrocarbon oils into an enclosed member. The spraying means communicates with the discharge end of the heating means and the inlet port of the enclosed number. The spraying means is capable of spraying the heated tars or hydrocarbon oils into the en- closed member to enhance the separation of the water from the tars or hydro- carbon oils. The enclosed member collects and disposes of the dehydrated tar or hydrocarbon oil through a first outlet and also has a second outlet for removal of the water in the vapor state from the vicinity of the tar and/or hydrocarbon oil in the enclosed member. The second outlet is adapted for com- munication with a scrubbing means that removes noxious chemicals from the water vapor to make the water vapor or water suitable for release to the environment.
