Definitions

  • FIG. 1 is a flow diagram of the process of the invention.
  • fatty acid esters of vegetable origin are coconut fat or palm kernel fat, palm oil, cottonseed oil, olive oil, soybean oil, peanut oil, linseed oil, rapeseed oil, castor oil, etc.
  • Mixed fatty acid esters of animal origin are, for example, butter fat, chicken fat or goose fat, lard, mutton tallow or beef tallow, suet and bone fats, and also a large number of various fish fats and oils, train oil, blubber, whale oil, as for example menhaden oil, herring oil or sperm oil, cod liver oil, etc.
  • mixtures of fatty alcohols may be separated which are obtainable by hydrogenation of fatty acids or fatty acid esters, while these fatty acids may be derived, for example, from the above-mentioned natural fats.
  • the lighter or oil phase consists substantially of the liquid components of the starting mixture, and the heavier phase represents a suspension of the solids in aqueous wetting agent solution.
  • the wetting agent solution is now partly or completely removed from this suspension according to the invention.
  • complete removal of the wetting agent solution is meant an operation in which the wetting agent solution is separated until only amounts of liquid mechanically adhering to the solids are left, so that the solids are no longer obtained in a flowable state, but are obtained for example as a wet filter residue.
  • an aqueous phase for example, water or electrolyte solution, is added in such amount that the solids again become flowable and may be added as a liquid to the next stage of the process.
  • the flowable aqueous slurry of the solids suitably contains 30 percent to 90 percent by weight, preferably 40 percent to 70 percent by weight of aqueous phase.
  • FIG. 2 a flow diagram for the renewed separation, at higher and lower temperatures, of both fractions obtained in the first separation step is illustrated.
  • the starting mixture, to be separated is pumped by the pump 1 through the scraping condenser 2 into the mixer 3.
  • This is preferably constructed in the manner described above. It consists of single mixing chambers through which the starting mixture is successively passed.
  • the starting mixture leaving the cooling and crystallizing scraping condenser 2 is first combined with more concentrated wetting agent solution through line 4.
  • Water free of wetting agent, or electrolyte solution free of wetting agent can be added through line 17, and wetting agent solution recovered from the solid fractions and recycled, is added through line 14.
  • I t/h (1,000 kg/h) of this starting mixture was cooled in the scraping condenser to 5C.
  • the pasty mix.- ture of oil and solid ingredients obtained was first admixed with 0.3 t/h of more concentrated and subsequently with 1.2 t/h of more dilute wetting agent solution, so that the dispersion leaving the mixer contained, per one part by weight of the cooled starting material, 1.5 part by weight of wetting agent solution.
  • This wetting agent solution had a wetting agent content of 0.25 percent by weight of sodium decylsulfate and an electrolyte content of I percent by weight of MgSO
  • the dispersion was then separated into an oily and an aqueous phase.
  • EXAMPLE 7 This example describes the processing of an undistilled fatty acid mixture (Acid N0. 204, Saponification N0. 207, I N0. 49, NF 0.9 percent) obtained by the cleaving of beef tallow of technical quality, into olein and commercial stearin with use of an apparatus according to FIG. 2, whereby the fractions obtained in the first separation step were separated in one successively arranged step each (warm step or cold step). Part of the wetting agent solution was withdrawn in each case. In the conventional operation this occurred after the hot or cold stage, i.e., the wetting agent solution was removed after melting the solid fractions downstream of the separators l0 and 10a by valves (not shown). The centrifuges 26, 38 and 41 operating as concentrators were avoided by lines which are not shown in FIG. 2 for reasons of good visibility. in the operation according to the invention part of the wetting agent solution was removed from the cold suspensions,
