Refining crude tall oil into biofuels using distillation
A recently granted patent (Publication Number: US11987768B2) discloses a method for refining crude tall oil, involving a series of steps to separate various components. The method includes evaporating tall oil material in different evaporators at specific temperatures and pressures to obtain fractions containing different substances like fatty acids, resin acids, and neutral substances. Further distillation processes are employed to obtain crude fatty acid fractions from different fractions obtained earlier in the process. The patent also emphasizes the recovery of specific fractions like crude sulphate turpentine and water, along with ensuring that the total amount of restricted metals in the combined crude fatty acid fraction is below 20 ppm.
Additionally, the method outlined in the patent involves the recovery of tall oil rosin fractions and the production of rosin soap from these fractions. The patent also provides specific ranges for the feed to the first fraction, the impurity levels in the tall oil material, and the operating conditions for the various evaporators and distillation columns used in the process. Furthermore, the patent highlights the potential use of the recovered combined crude fatty acid fraction as a feed for hydroprocessing to produce biofuels or their components. Overall, the patent presents a detailed and systematic approach to refining crude tall oil, focusing on efficient separation and recovery of valuable components while meeting specific quality criteria.
