Abstract

See full text

Oxycombustion process wherein low ranking, gaseous, liquid, solid, optionally solid melting hydrocarbon fractions are used as fuels, having a vanadium content in an amount by weight from 50 to 5,000 ppm or higher, for producing energy, wherein magnesium is added as oxide, or as a water-soluble salt, the combustor being refractored and isotherm or quasi isotherm, flameless, working at temperatures comprised between 1,250° C. and 1,450° C. and under pressurized conditions, wherein the oxidant is oxygen, the oxidant being used in admixture with water or steam such that the ratio by moles oxidant:(water-steam) is comprised between about 1:0.4 and about 1:3 or the oxidant is used in admixture with flue gases recycled from the flue gases outletting the energy recovery equipments, wherein the water amount is higher than 30% by volume, optionally by adding water, the molar ratio oxidant:(water/steam) in flue gases being comprised from about 1:0.4 to about 1:3; the low ranking hydrocarbon fraction containing vanadium is fed in admixture with water or steam, such that the amount of water/steam in the mixture is at least 30% by weight with respect to the hydrocarbon fraction.
