Abstract:
1. A process for combustion of heavy oil residues with a low emission of SO x comprising: heating the heavy oil residues at a temperature at least equal to a softening point of the heavy oil residues; preparing a dispersion of the heated heavy oil residues in water, and combusting the dispersion of the heavy oil residues in water; wherein the heavy oil residues have a softening point higher than 25° C., and wherein the dispersion of the heavy oil residues in water comprises: one or more dispersing agents selected from organic sulfonates of alkali metals or of ammonium; one or more desulfurizing agents selected from the group consisting of CaCO one or more desulfurizing agents with stabilizing and anticorrosive properties selected from the group consisting of MgO, Mg (OH)
