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 present invention makes it possible to avoid these drawbacks.
  • the process according to the present invention is characterized by the fact that a hydrocarbon emulsion is produced in the first stage in water, whether polluted or not and in a second stage, a fuel is added to this emulsion. solid or liquid form by vigorous stirring.
  • a surfactant or mixtures of surfactants -active in a proportion of 1 to 3 per 1,000.
  • the nonionic polyoxyethylene derivatives having an H.L.B. can advantageously be used as surfactants. (Hydrophylic Lipophylic Balance) between 15 and 20 and preferably around 17.
  • This colloid will have the following triple role: - stabilize the emulsion, - avoid settling, - maintain a pseudo-plasticity.
  • 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.
  • a mixture of this emulsion and a solid or liquid fuel is produced in a suitable brewing apparatus 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.
  • a stabilizing agent such as for example xanthan gum.
  • 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.
  • Example 2 If the following mixture is vigorously kneaded: 40% water polluted by 0.5% phenol 15% domestic fuel 45% of South African coal ground as indicated in Example 1, a product is obtained which is presented in two phases: - a muddy phase comprising coal and domestic fuel, - an aqueous phase.
  • 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.
  • river sand but is also applicable to polluted "black tide” type marine sand: or 100 gr. river sand polluted by heavy fuel oil n ° 2 in the proportion 70% sand, 30% heavy fuel.
  • 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 process according to the present invention can be used to make mixtures with: - polluted waters comprising: hydrocarbons, alcohols, phenols, amines, soluble mineral salts of organic or vegetable matter or the like; - liquid hydrocarbons, hydrocarbon muds (oily muds type), organic animal or vegetable muds, organic or vegetable mineral fats, tar from drilling muds or the like: - mining products or by-products such as "schlamms", dedusting fines, activated carbon, carbon black sludge, petroleum coke, vapocracker, solidified tar, pitches, earth or polluted sands or the like.
  • 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.
