    • Isolation of the sterol component of the neutrals fraction of saponified tall oil pitch is disclosed. Sterol isolation is accomplished by a liquid-liquid extraction from the tall oil pitch-derived neutrals, resulting in a hydrocarbon (preferably heptane) phase at a relatively high temperature (preferably greater than 50 DEG C) to which small amounts of an alcohol solvent, preferably methanol, is added. To the hydrocarbon/alcohol/neutrals solution is then added water of a higher temperature, preferably 60-70 DEG C to result in the formation of two separate phases. The blended solution is allowed to cool slowly, with agitation, to facilitate crystallization of sterols. The sterols are isolated by filtration and then washed with hydrocarbon solvent to result in high yield and high purity.

    • Method of recovering sterols from tall oil pitch which contains steryl esters. In the method the tall oil pitch is subjected to a transefterification reaction with a lower alcohol in a reaction zone to provide a reaction product mixture containing lower alkyl fatty acid esters, free sterols, and at least some unreacted steryl esters. The invention comprises separating the transesterified esters from the reaction product mixture to form a sterol rich fraction which contains free sterols and unreacted steryl esters, liberating sterols from the unreacted steryl esters to form further free sterols, and recovering and optionally purifying the free sterols. The recovery of free sterols can be increased to up to 80 wt % or more while avoiding the formation of undesired side streams containing troublesome impurities.
    • 从含有甾醇酯的妥尔油沥青中回收固醇的方法。 在该方法中,将妥尔油沥青与反应区中的低级醇进行转化反应以提供含有低级烷基脂肪酸酯,游离甾醇和至少一些未反应的甾酯的反应产物混合物。 本发明包括从反应产物混合物中分离出酯交换酯形成富含固醇的级分,其含有游离甾醇和未反应的甾酯,从未反应的甾醇酯释放固醇以形成更多的游离甾醇,并回收和任选地纯化游离甾醇。 游离甾醇的回收率可以提高至高达80重量%或更多,同时避免形成含有麻烦杂质的不期望的侧流。

    • A process and apparatus for recovering crude tall oil are disclosed. Acidulation of a crude tall oil soap stream generates a spent acid stream that comprises lignin and entrained crude tall oil. By subjecting the spent acid stream to dissolved gas flotation, a lignin phase comprising entrained crude tall oil can be recovered and causticized, resulting in recovery of most of the crude tall oil that was present in the spent acid stream. A clarified spent acid stream is also generated, which can be treated with caustic and utilized for a soap washing process that integrates easily into the overall CTO recovery process. The apparatus comprises a crude tall oil acidulation unit, a dissolved gas flotation unit, a causticizing unit, and a soap separation unit. The inventive process marries dissolved gas flotation, a well- known water treatment process, with causticization of a recovered lignin phase, a step known from batch acidulation, to improve overall tall oil recovery from a continuous process.
    • 公开了回收粗妥油的方法和装置。 粗的妥尔油皂液流的酸化产生包含木质素和夹带的粗妥尔油的废酸流。 通过使废酸流进行溶解气体浮选,可以回收包含夹带的粗妥尔油的木质素相并苛化,导致废酸流中存在的大多数粗妥尔油的回收。 还产生澄清的废酸流,其可以用苛性碱处理并用于肥皂洗涤过程,其容易地整合到整个CTO回收过程中。 该装置包括粗妥质油酸化单元,溶解气浮选单元,苛化单元和皂分离单元。 本发明的方法将溶解气体浮选,已知的水处理过程与回收的木质素相的苛化相结合,这是从批次酸化中已知的步骤,以从连续方法提高整体妥尔油的回收率。
