  • Patent number: 8408396
    Abstract: The invention is a process for the beneficiation and utilization of various kinds of coal and shale oil as a solid fuel for thermoelectric power stations. The beneficiation process is performed underground, near to the place of beneficiation waste stowing, using aqueous salt solution with a density between those of the target component and waste rock. The regeneration of heavy liquid from final beneficiation tailings is performed by washing with non-aqueous volatile liquid, with subsequent drying by the subsurface heat after placing these tailings in the worked-out space. The resulting vapors are compressed and condensed; thus regenerated non-aqueous liquid is returned for washing the beneficiation tailings, while effluents produced by washing are separated into aqueous and non-aqueous components by heat released at the liquefaction of the non-aqueous liquid vapors. The enriched solid fuel remaining in the floatable state is delivered by its flow to the thermo-electric power plant.

    Abstract: Enhanced methods for separating of overlapping density porous materials are provided. The methods of the invention exploit the differences in the porosity of porous feed materials compared to that of the solid plastics. In the first stage, air is forced out of the pores of a porous feed material. In the second stage, a solution, having the appropriate density, is forced into the pores. This increases the density of the porous material relative to the density of the solid plastics. As a result, the porous material can be made to sink, while the solid plastics continue to float.

  • Publication number: 20090065404
    Abstract: A process for the separation of a multiple domain solid feedstock such as that derived from ASR, WSR, and/or ESR is disclosed which comprises granulating the feedstock to produce particles each of substantially a single domain, with each type of particle having a different density. The particles are introduced into a suitable aqueous salt solution. Aqueous salt solutions containing cations comprising sodium, calcium and ammonium, and anions comprising nitrate, bromide, and chloride are useful. A dispersion mixer having a high shear and/or turbulent zone is utilized to disperse agglomerated particles and a quiescent hydrogravity tank is utilized to effect binary separation of the mixture of particles into a stream with a higher average specific gravity, and a stream with a lower average specific gravity. A higher degree of product purity can be obtained by subjecting either of the product streams from the first hydrogravity stage to additional stages of hydrogravity separation.

  • Patent number: 7169263
    Abstract: The invention relates to a coarse dirt collector (7) for removing coarse material from a pulper (1). The coarse dirt collector (7) comprises a support arm (8) with a collecting basket (9). The collecting basket (9) consists of a frame (11) on which tines (Z) are fixed by means of a grid. The coarse dirt collector can be pivoted into and out of the pulper, to which end it moves about an axis of rotation (A) positioned at an angle to the plane that is perpendicular to the longitudinal axis (P) of the pulper. Said angle is between 20° and 40°. The advantage of said device is that the coarse dirt collector (7) has to carry out only one movement between its collecting and unloading position and unloading can take place automatically without need for a special scraping device. Because of the position of the tines (Z) there is no risk of undesirable loss of coarse material prior to unloading.

  • Patent number: 6988622
    Abstract: Mechanically harvested chili-pepper plants are sized into chunks and introduced into a water flotation system. Water is added at the top of a flotation vat and, for the most part, is withdrawn at the bottom using a venturi unit. The balance of the water is recovered as spillover from the top of the vat carrying the floating material. If the rate of water withdrawal at the bottom of the vessel is controlled such that it is as high as possible but less than what produces turbulence in the vat, the pulp material will drop with heavy seeds to the bottom with the extracted water while all other materials are skimmed away at the top. The very small differential in density between the pepper pulp and the rest of the plant and debris is sufficient to separate them under these specific conditions.
