Abstract
A fuel comprised of liquid and solid refinery waste streams is described. The fuel is a blend of a heavy paraffinic oil, an emulsified waste oil, water and solids. The fuel is blended both to achieve a viscosity which enables the fuel to be pumped, and to obtain the required fuel value for burning in a cement kiln while simultaneously having a high solids content. The amount of the heavy paraffinic oil present in the final fuel is related to the ambient temperature at which the fuel is to be pumped, stored and consumed. Typically, the higher the ambient temperature the more heavy paraffinic oil that can be used in the fuel blend.
