Abstract: A process for producing a delayed coker quench stream for use in the quench cycle of a delayed coking process wherein a waste stream containing water, organic compounds and solids is treated to produce a coker feed stream containing from about 5 to about 35% by weight solids, water and less than about 6% by weight mobile organics, the solids having a particle size distribution such that greater than about 70% of the total solids volume comprises solids having a particle size of less than about 15 microns.

Abstract: A process for producing a fuel composition from a waste stream containing a liquid, organic component, water and a mixture of inorganic and organic solids wherein the waste stream is separated into an oil fraction, a water fraction and a solids fraction, the solids fraction being de-watered to produce a de-watered solids fraction containing less than about 60% by weight water, the de-watered solids fraction being admixed with oil and heated in a heating apparatus wherein the de-watered solids fraction and oil are subjected to heat exchange conditions at a temperature and for a time sufficient to evaporate water and produce a fuel composition containing less than about 15% by weight water, the apparatus having means for inducing forced convection condition in the mixture of de-watered solids and oil to prevent solids settling and enhance heat exchange heating.
