Definitions

  • the present invention relates to a process for preparing a emulsified fuel, i.e. an emulsified mixture of water and at least one organic compound, in order to distribute it like other liquid fuels, notably petroleum fuels and domestic fuels.
  • the organic phase is a petroleum product, a vegetable or animal oil or any other fuel used in particular in motor vehicles and boilers domestic and more generally for powering internal combustion engines or others and for powering energy-producing devices.
  • the invention also relates to its industrial implementation device in the form of units industrial fixed or transportable.
  • emulsified fuel is well known to the person skilled in the art. trade, but difficult to implement due to the lack of stability of the emulsions fuels used.
  • the storage stability of these emulsions was the subject of a definition by the Hydrocarbons Department of the French Ministry of Industry. According to this administration, a water in diesel emulsion is considered to be stable storage at room temperature, if no phase shift is observed after at least four months.
  • patents DE 19 704 874, DD 216 863 and WO 95/33023 describe in particular methods and devices for obtaining combustible emulsions on board land vehicles, Diesel type. Such fuels are obtained by mixing the components and emulsifying this mixture on the vehicle itself.
  • the emulsions described are emulsions in which the phase external can be aqueous, which can be subsequently reversed by dilution in an organic phase, as in patent DE 19 704 874.
  • the emulsion described in patent WO 95/33023 contains less than 20% by volume of water, the phase aqueous constituting the external phase.
  • a fuel is claimed aqueous emulsified, hydrocarbon in water containing 20 to 80% by volume of water, the water constituting the external phase of the emulsion, 2 to 20% by volume of an alcohol, the supplement being formed of hydrocarbons and a nonionic emulsifier.
  • the hydrocarbon is gasoline, kerosene, gas oils, fuels synthetic or derivatives of vegetable or animal oils.
  • This request claims in addition a process for the bulk preparation of this emulsified fuel, stable at least three months and consisting, on the one hand, of a mixture of the hydrocarbon and the emulsifier and, on the other hand, a mixture of water and alcohol.
  • the present invention relates to the preparation of such emulsified fuels whose external phase is an organic compound and which can be stable for a sufficiently long period, for example more than 4 months, to allow their storage in industrial quantities and subsequently their distribution like fuels or fuel at the pump.
  • This preparation process of the present invention allows the preparation emulsions of industrial volume, the water / liquid ratio homogenized in the capacity, being adjusted during manufacture to obtain the desired water content in the final combustible emulsion.
  • the stages of preparation of the homogenized liquid, organic compound (s) / additives, and emulsification of the liquid with water are very important or even essential. So, he will be possible during the homogenization and emulsification stages to heat and to cool the liquid contained in the homogenization capacity.
  • the method according to the invention comprises a step 1p prior to step 1 , during which the additives necessary for the emulsion are mixed with at least one solvent.
  • the mixture of additives from step 1p is advantageously obtained by diluting the additives in at least one solvent, starting with the most viscous additive and ending with the least viscous additive, each of these dilutions being preferably carried out in a capacity equipped with at least one agitator with an axial pumping flow rate for good homogeneity and possibly with means for heating and cooling its capacity in order to improve their dilution and their homogenization.
  • additives capable of improving a or several required properties of the fuel according to the invention are introduced in the emulsion formed, either in the organic phase or in the aqueous phase.
  • the solvent used in step 1p is chosen from the group comprising at least one of the organic compounds used to form the emulsion, a solvent of alcohol, ketone, ester or ether type, or one of the additives of the emulsion whose solvent properties vis-à-vis the other additives are sufficient.
  • the organic compound (s) according to the present invention is (are) chosen from petroleum fuels, gasoline, diesel, kerosene, fuel domestic products, these products possibly being supplemented with oxygenated type TAME (methyltertioamylether) or MTBE (methyltertiobutylether) for gasolines, of type DME (dimethylether), DMM (dimethoxymethane), or TEP (triethoxypropane) for gas oils, or vegetable or animal oils, refined or no, or their esterified derivatives.
  • TAME methyltertioamylether
  • MTBE methyltertiobutylether
  • the foam concentrate system include at least one device allowing the circulation of the liquid in the bypass loop.
  • the aqueous phase is injected into the homogenized liquid, compound (s) organic (s) / additives, at a flow rate Qe proportional to the flow rate Qc of circulation of the volume V of liquid in said capacity, the ratio Qe / Qc varying from 0 to 1.
  • the Qe / Qc ratio varies from 0.05 to 0.20.
  • This aqueous phase can also contain specific additives aiming to avoid contamination of water such as biocides or anti-freeze especially in winter to avoid crystallization of water and breakage of the emulsion.
  • the present process is particularly suitable for the preparation of fuels emulsified water in oil, in particular water / diesel emulsions or water / petrol for combustion in internal combustion engines installed on motorized vehicles, in particular urban vehicles for which a reduction of polluting exhaust emissions by immediate action on the fuel is particularly desirable.
