Abstract
Hydrocarbon-containing liquid waste sludges from refinery waste streams can be disposed of by blending with the feedstock being passed to a fluid catalytic cracking unit. Preferably, the sludge is premixed with a hydrocarbon, such as a light oil, prior to mixing with the feed.
Claims3
A process for the disposal of a hydrocarbon-containing petroleum refinery liquid sludge waste stream in the form of an oil-in-water emulsion, which comprises mixing the sludge with a hydrocarbon oil to cause the oil-in-water emulsion to invert to a water-in-oil emulsion and mixing the water-in-oil emulsion with a feedstock for a fluid catalytic cracking reactor, and feeding the water-in-oil emulsion and the feedstock to the fluid catalytic cracking reactor in which the oil and the feedstock are subjected to catalytic cracking.
