Patent ID: 8453584

Claim:
A method for handling a substance from which a combustible gas volatilizes inside an apparatus with a high degree of hermeticity, which comprises steps of: mixing, in a mixing apparatus having a high degree of hermeticity, a mixture comprising air, oil mud and oil mud absorbent, the oil mud absorbent being selected from the group consisting of biomass, organic powders and mixtures thereof, the mixing including: volatilizing a combustible gas contained within the oil mud mixed with the air and biomass, while introducing the air into the mixing apparatus and diluting the volatilized combustible gas to a concentration that diminishes exploding or igniting of the combustible gas, and the air being introduced into the apparatus with a high degree of hermeticity, and forming a solid fuel from the mixture comprising oil mud and oil mud absorbent, transporting the solid fuel from the mixing apparatus using pneumatic pressure to a cement kiln, burning the solid fuel in a burner of the cement kiln and converting the solid fuel into a clinker, and feeding air exiting from the mixing apparatus, which was used for diluting the combustible gas, into the cement kiln and cooling the clinker formed therein using the air from the mixing apparatus.
