The present invention relates to process for de-acidification of fats and oils, to obtain micronutrients, to obtain a fatty acid product, and recovery of refined oils, comprising: feeding pre-treated oil feed stream (1) to a vacuum steam stripping section, stripping off volatile phases. Feeding the stripped off the volatile phases to a condensing stage providing a condensed phase (A) and a vapour phase (E). Sending the condensed phase (A) to a vacuum distillation operation and sending the vapour phase (E) to a cold condensation stage. Subjecting the condensed phase (A) to a vacuum distillation operation, and obtaining a high temperature distillate (6) and a stream of volatiles (C). Feeding the vapour phase (E) from the high temperature condensing stage along with the stream of volatiles (C) from the vacuum distillation operation to the cold condensation stage obtaining a stream of non-condensable gases and a cold temperature distillate (5), letting the stream (4) of non-condensable gases continue to a vacuum system, and recovering from the vacuum steam stripping section a stream of refined oil (7). |
