Definitions

  • the present invention relates to a process for producing homogeneous stable pumpable and injectable mixtures of industrial residues such as polluted water, hydrocarbon waste and coal or combustible industrial waste.
  • the use of alcohol makes the mixture dangerous, which means that special storage arrangements have to be made.
  • the alcohols used generally have flash points of between 11 and 25 ° C which means that the storage constraints which for flash points below 55 ° C and especially below 21 ° C require compliance with the storage constraints. provision of fire zones, explosion-proof motors ...
  • the present invention makes it possible to avoid these drawbacks by proposing to produce homogeneous mixtures of water, hydrocarbons, coal or industrial waste and characterized in that a stable emulsion of hydrocarbons is first produced in water via a nonionic surfactant having an HLB between 15 and 20 and that in a second step, this emulsion is mixed with either coal or combustible industrial waste, and this in the presence of a colloid.
  • H.L.B. stands for Hydrophily-Lipophily Balance, which translates to Hydrophilic Lipophilic Balance.
  • a compound having an H.L.B. high is hydrophilic and promotes the formation of fine oil droplets in water.
  • Such surfactants at H.L.B. high may be non-ionic polyoxyethylene derivatives including H.LB. is close to 17, these agents will be used in proportions of 1 to 3 per 1,000 of the water + hydrocarbon mixture.
  • colloid means that no special storage rules have to be observed because their flash point is close to or greater than 100 ° C.
  • this colloid will be added to the products to be emulsified in the proportion of 0.5 to 1%.
  • the emulsion produced in the first phase of the process is an emulsion of the hydrocarbon in water and not the reverse.
  • the colloid will be a xanthan gum.
  • pseudo-plasticity is meant that the liquid will become more fluid when agitated; this is important when the final product is intended to be stored in a tank then pumped and injected.
  • the aqueous emulsion can also be facilitated by adding light and fluid hydrocarbons acting as solvent or diluent.
  • a mixture of this emulsion and a solid or liquid fuel is produced in an appropriate stirring device of any known type.
  • a ground solid fuel or even in some cases only crushed, the grinding being done later. It is also possible to use a solid fuel, either pure or mixed with impurities.
  • dispersing agents such as poly- naphthalenes sulfonates lignosulfonates or polyacrylates.
  • the mixture thus obtained is left to stand and after a few hours there is a slight settling of particles greater than 100 microns.
  • a dispersing agent such as xanthan gum in the proportion of 0.15 per 1,000 is added to the previously obtained homogeneous mixture, there is no more settling, the particles remaining very mobile in the mass.
  • the homogeneous final mixture thus obtained from industrial waste and lean coal can be stored in tanks, then pumped and injected into heating body nozzles.
  • such a mixture owing to its homogeneity and its stability, can be stored in a tank then pumped and injected into furnace nozzles and boilers so that a fuel which can be used is obtained. from industrial residues and pollution products.
  • This example illustrates the use of the process according to the invention for extracting the heavy fuel oil incorporated in sand, that is to say for recovering this heavy fuel oil which is incorporated in a combustible mixture which can be used industrially while cleaning the sand.
  • the following emulsion is prepared: 80 gr. of water + 20 gr. of White Spirit, shaking the mixture vigorously in the presence of 0.2 gr. ethoxylated nonylphenol.
  • the purpose of the dispersants mentioned above is to act on the zeta potential of the particles in order to promote their dispersion. It is possible to use: alkali carbonates or silicates; polynaphthalenes sulfonates; lignosulfonates; polyacrylates.
