Definitions

  • the invention relates to a process for working up obtained in the production of vegetable oil solid organic waste, mainly consisting of press residues of oil crops and / or oilseeds, and oily wastewater.
  • the invention further relates to the advantageous use of the products of the method according to the invention in the cultivation of oil palms, as well as for energy.
  • the invention is suitable for use in palm oil production.
  • the solid waste is usually incinerated to produce energy for the oil mill, which is associated with heavy smoke and therefore very stressful for the environment and humans.
  • Wastewater from oil extraction is collected in sewage ponds. Some of the organic matter is biodegraded anaerobically. In addition to the strong odor nuisance caused by fumigants, carbon dioxide and methane are formed to produce the climate-damaging gases. In order to avoid these disadvantages, the smoke development in the incineration of solid waste and the environmental impact of the biological wastewater treatment, F. Schuchardt described a method in which the treatment of the wastewater by anaerobic biological reactions is carried out in a fermentation reactor, so that Carbon dioxide and methane can be collected and recycled in a climate-friendly manner. The treated wastewater is then mixed in compost rents with biological waste and composted into fertilizer.
  • the present invention seeks to provide an alternative process which converts the waste into nutrient-containing water suitable for irrigating the oil crop plantation and produces a carbonaceous solid fuel.
  • the eg mixed with heating oil is suitable for energy production by burning.
  • the solid, organic wastes are comminuted and mixed with the wastewater in a stirred, heated reactor to form a suspension, the pH of the suspension is adjusted in the acidic range, the atmospheric oxygen is removed from the reactor by flushing with inert gas and the reactor closed airtight and pressure-tight and the suspension heated to at least 170 ° C and maintained at elevated pressure for at least 0.5 hours, wherein the solid, organic waste is converted mainly to a carbon-rich solid and wherein the originally contained in the wastewater from the resulting oil, carbon-rich solid is sorbed and then wherein the suspension is cooled, removed from the reactor and separated into a coal and a wastewater fraction.
  • the oil / water emulsion as our own experiments have shown, so stable that they by conventional means, such as the additions of surfactants, boiling, acidification to a pH of 2, centrifuging or the addition of activated carbon, not too break is.
  • the reason for the high stability of this emulsion is presumably the free fatty acids and glycerides also present in the wastewater, in particular including the monoglycerides, which are very effective emulsifiers. Thereafter, it was not expected that the emulsion would be broken by the HTC process, and that would solve the one important problem of this waste treatment, the treatment of waste water loaded by the oil / water emulsion.
  • the basic and well-known chemical processes of the HTC process are that hydrogen and oxygen atoms from the compounds in which they are present in the biomass, z. As glucose, are dissolved out and connect to H 2 0. In order not to interfere with these chemical processes, the process must be carried out under exclusion of air. Air debris must be removed by purging with inert gas prior to heating the suspension from the reactor.
  • the energy balance of these chemical processes is overall positive, the actual amount of energy gain depends of course on the type of biomass used. However, in addition to the energy balance of the chemical processes, the energy balance of the process engineering procedures of the process must also be taken into account. So much heating energy is needed because the HTC process only runs above 170 mi t economic speed. In addition, because of the high temperature level at which the HTC process expires, good thermal insulation of the reactors is required.
  • the process can be carried out both batchwise and continuously or semicontinuously, with suitable measures for supplying the starting materials and for removing the products being taken in the latter two cases.
  • the suspension is separated into a solid fraction and a wastewater fraction by means of mechanical separation processes, preferably decantation, filtration or centrifugation, or combinations thereof.
  • a preferred embodiment of the invention is the use of hardwood-rich solid product as a fuel, individually or in admixture with other fuels, eg. B. can be used as a suspension after mixing in heating or heavy oil.
  • a further preferred development of the invention consists in the use of the treated waste water for the irrigation of plants, preferably oil plants, wherein the waste water is previously neutralized, preferably with KOH.
  • the invention provides a process for working up solid and liquid wastes from vegetable oil production, which is distinguished by its simple apparatus and in which products are obtained which are unproblematic with regard to their disposal or which even advantageously take place at the location of the oil - Plantation can be recycled.

Abstract

L'invention concerne un procédé pour le traitement de déchets solides, organiques produits lors de la production d'huile végétale, par exemple la production d'huile de palme, principalement constitués de résidus de pressage des plantes et/ou des graines oléagineuses et d'eaux usées contenant de l'huile par carbonisation hydrothermale (HTC), l'huile se trouvant sous forme émulsionnée dans les eaux usées étant absorbée par les solides formés à partir des déchets solides, riches en carbone.
