Definitions

  • the present invention relates to a process for the selective separation of valuable substances with the aid of compressed C 2 - to C 4 ⁇ hydrocarbons.
  • liquid or solid process streams occur in large quantities either as waste or as secondary raw materials, for example as animal feed, or else processed, such as through appropriate clarification and purification measures.
  • loaded adsorbents are obtained, which are usually disposed of, since purification of the loaded adsorbents is uneconomical.
  • adsorbents such as activated carbon or diatomaceous earth
  • a disadvantage of all established processes that use adsorbents is that the adsorbents used do not separate them selectively, but that, depending on the specific surfaces of the adsorbents, valuable substances, such as aromas and odors, contained in the process streams are also bound to the adsorbents , which is why they usually contain significant amounts of these valuable substances.
  • no economic processes are known which, for example, make it possible to selectively separate valuable substances bound to adsorbents in the form of aromatic and odorous substances and to add further value.
  • lipophilic organic solvents are also used to obtain aroma and odor substances in the context of corresponding extraction processes.
  • the aroma and fragrance concentrates obtained in this way mostly contain a certain amount of residues of the organic solvents used, which leads to an easily understandable impairment of the product qualities.
  • adsorption materials are therefore also used, which are intended to remove the organic solvent residues from the products, but due to the physical properties of the adsorbents used, this does not take place to an adequate degree and why the flavor and odor concentrates are depleted in a disadvantageous manner by the adsorbents with regard to the sensory active ingredients.
  • fractional extraction is available, in which the different ingredients are extracted sequentially from the natural product using different process parameters such as pressure, temperature or entrainer feed and collected separately.
  • fractional separation is possible, in which the various ingredients are initially extracted together, but are then separated from the gas under different conditions.
  • the present invention therefore has the general task of providing a process for the selective separation of valuable substances with the aid of compressed C 2 to C 4 hydrocarbons, with which the desired products can be obtained in a relatively simple manner good quality.
  • “absorption” means the binding of valuable substances by liquids or solid substances.
  • “Adsorption” means the corresponding accumulation of valuable substances in the dissolved state on solid bodies, the adsorption being directly proportional to the surface of the solid adsorbent body used.
  • the present method is particularly suitable for valuable substances which are aromatic and / or odorous substances.
  • the valuable materials can also be in the form of organic intermediates or end products, as obtained in particular with the help of biotechnological processes. This primarily includes fermentation processes.
  • the valuable materials can also be bound to catalysts, in which case not only the actual valuable materials are obtained, but also the cleaned carrier materials.
  • the process according to the invention is preferably carried out at temperatures of 1 120 ° C. and pressures of ⁇ 50 MPa, the temperature being particularly preferably between 20 and 40 ° C. and the pressure between 0.5 and 10 MPa.
  • Compressed ethane, propane, butane or mixtures thereof have proven to be particularly suitable C 2 - to C 8 hydrocarbons, the present invention providing in certain applications the compressed hydrocarbon (mixture) entrainer, such as dimethyl ether or alcohols, preferably in proportions of 0.5 to 50% by weight, more preferably 5 to 20% by weight.
  • the compressed hydrocarbon (mixture) entrainer such as dimethyl ether or alcohols, preferably in proportions of 0.5 to 50% by weight, more preferably 5 to 20% by weight.
  • the method according to the invention is particularly suitable for a batchwise procedure. Depending on the area of application, the claimed method can also be carried out continuously or semi-continuously.
  • solid substances with large inner and / or outer surfaces have been shown to be suitable, and preferably those with surfaces> 0.1 m 2 / g, preferably> 10 m 2 / g, more preferably> 100 m 2 / g and more preferably> 500 m 2 / g (according to BET DIN 66131) and / or fluid substances.
  • Activated carbons, clays, silicas, diatomaceous earth, aluminosilicates, zeolites and / or polysaccharides, such as cyclodextrins, are particularly suitable solid substances.
  • the present method takes into account in particular starting materials that come from food production and / or production or from aroma production, but also from juice, wine and spirits production and processing and / or meat, fruit and vegetable processing ,
  • the method according to the invention has proven to be particularly advantageous in the production of natural, nature-identical and / or synthetic aroma and fragrance substances, which the present invention also takes into account.

  • the present invention also provides that the pressure vessel can be coupled to a separator and that the extracted valuable substances can be separated, for example in the form of aroma and odorous substances, preferably by lowering the pressure and / or increasing the temperature.
  • the process according to the invention also enables the hydrocarbons used as extractants to be recycled, which also contributes to its economy.
  • the invention also provides a special process variant in which the actual process is preceded by an adsorption step: first, solid substances with large inner and / or outer surfaces> 0.1 m 2 / g, preferably> 10 m 2 / g, more preferably> 100 m 2 / g and even more preferably> 500 m 2 / g (BET DIN 66131) loaded with valuable substances; this loaded complex is then treated with compressed C 2-4 hydrocarbons as described.
  • the present method with its preferred variants is not only suitable for the selective separation of adsorbed or absorbed aroma and odor substances from carrier materials which contain these valuable substances only because of the insufficient selectivity of the adsorbents. Rather, this method can also be used to produce high-quality aroma or odorant concentrates, for example by adding an adsorbent to commercially available concentrates obtained with the aid of organic solvents or with compressed CO 2 . As a result, sensory lead compounds are selected from the concentrate and subsequently the adsorbents loaded in this way, such as treated to be claimed. In this way, typical lead compounds of the aromas and fragrances are selectively concentrated, which leads to high-quality end products.
  • the present invention also takes into account the removal of less valuable compounds which are bound to adsorption or absorption materials.
  • the main focus is on the extraction or purification of the carrier materials and less on the substances adsorbed or absorbed on them.

Abstract

L'invention concerne un procédé de séparation sélective de matières à l'aide d'hydrocarbures C2-C4 comprimés, tels que l'éthane, le propane et/ou le butane. Selon ledit procédé on utilise un matériau de départ qui contient lesdites matières à l'état absorbé et/ou adsorbé. Pour ce procédé, qui est mis en oeuvre à des températures = 120 DEG C et à des pressions < 50 Mpa, de préférence en continu, on utilise, comme matériaux de départ, des charbons actifs, des argiles, des acides siliciques, des zéolites ou des polysaccharides chargés avec lesdites matières. Le procédé présenté permet en particulier d'obtenir des substances aromatiques et odorantes à partir de matériaux de départ qui proviennent de la production et/ou de l'extraction de produits alimentaires et, de préférence, de l'extraction d'arômes, de la production et du traitement de jus, de vins et de spiritueux ou du traitement de la viande, des fruits et des légumes.
