ABSTRACT:
A tar separating device for separating tar from hot rinsing liquid, specifically, the rinsing liquid of a receiver of a coke oven battery including a container having a rinsing liquid inlet, a solids removal device for removing solids from the liquid as the liquid enters the container, a tar dewatering chamber located in the container near the inlet such that the rinsing liquid entering the container flows over the outer surface of the chamber and a tube in the container for conveying rinsing liquid into the tar dewatering chamber. The inlet to the tube is located at a point distant from the rinsing liquid inlet to the container. At the tube inlet point, the temperature of the liquid is lower than that at the inlet. The present invention utilizes this temperature differential to effect a particularly distinct separation between the tar and the water. The device further includes means for separately removing the tar and the water from the dewatering chamber.
