  • Patent number: 7713416
    Abstract: A process for transforming sludge into NPK type granulated fertilizer in which the energy consume is reduced a 90% thanks to the addition of a special filtration step in which the water content is reduced a 50% and the remaining water is evaporated by the exothermic reaction occurring in the process. Additionally, the process of the present invention includes mechanisms that allow some of the by products generated by some of the reactions, to adsorb crystallization water and reduce the humidity of the mass without using external energy.
    Type: Grant

  • Patent number: 6676917
    Abstract: A process for the production of hydrochloric acid and neutralized sulfates comprising: reacting sulfuric acid with an alkaline metal chloride in order to obtain a liquor containing hydrochloric acid, an acid alkaline metal sulfate and an excess of sulfuric acid; separating the hydrochloric acid from the liquor containing the hydrochloric acid, the acid alkaline metal sulfate and the excess of sulfuric acid; neutralizing the acid alkaline metal sulfate and the excess sulfuric acid by adding to the remaining liquor after the separation of the hydrochloric acid a neutralizing agent to obtain a neutralized mass; cooling the neutralized mass to crystallize the neutralized alkaline metal sulfate and obtain neutralized alkaline metal sulfate crystals; and separating the neutralized alkaline metal sulfate crystals from the liquor.

  • Patent number: 6585900
    Abstract: A process for the treatment of sludge which produces a dry sludge free of pathogenic and non-pathogenic microorganisms enriched with nitrogen which can be used as a fertilizer, and which uses as raw materials: elemental sulfur, formaldehyde, ammonia, urea, chlorine, and sulphuric acid, and comprises the steps of feeding the sludge into a pre-dryer into which is fed a hot gas stream containing sulfur trioxide produced by the combustion and catalytic oxidation of sulfur with air and finally completely drying the sludge by feeding it into an ammoniator.

  • Patent number: 6419887
    Abstract: A process for the treatment of residual liquors from the ammoniation and carbonation of alkali metal salts containing ammonium salts, sodium salts, soluble sodium bicarbonate, ammonium bicarbonate and water and producing purified ammonium salts, comprising the steps of: eliminating the sodium bicarbonate, and ammonium bicarbonate mixed in the residual liquor by mixing sulfuric acid with the residual liquor in order to obtain a solution of an ammonium salt and a sodium salt; and separating the sodium salt from the solution or mixing the solution with sodium chloride crystals in order to obtain a magma containing sodium salt crystals and ammonium chloride crystals and separating the sodium salt crystals and the ammonium chloride crystals from the magma.

  • Patent number: 6398840
    Abstract: A process for treating sludge comprising the addition of sulphuric acid and anhydrous ammonium to the sludge inside a granulator in order to produce an exothermic reaction which generates sufficient heat to evaporate the water contained in the sludge, thus eliminating all the pathogen and non pathogen microorganism, and producing a dry product having a low pH, free of polluting agents and a high commercial value.
