Abstract:
A process for industrial-scale preparation of an emulsified fuel comprising an aqueous phase in a continuous organic phase selected from the group consisting of petroleum-based fuels, petrols, gas oils, kerosenes and domestic fuel oils, which contains less than 20% by volume of water, and at least one additive necessary for forming the emulsified fuel, said process comprising the steps of:a) preparing a liquid by introducing the at least one surfactant additive into a tank equipped with at least one agitator with axial pumping displacement and containing the organic phase, the volume of the liquid being defined as V; b) homogenizing the volume V of liquid, with the agitator to obtain a ratio Qc/V&gE;100 hâˆ’1, where Qc is the circulation rate of the liquid inside the tank; c) circulating the homogenized liquid in a branch loop emerging from the tank, and through at least one emulsifying system located on said loop, at a rate such that: 0 hd) feeding an aqueous phase necessary to form an emulsion into the branch loop, upstream of the emulsifying system; and e) maintaining the homogenization in the tank and the circulation of the liquid in the branch loop until the emulsion acquires a desired characteristic of storage stability.
