In order to reduce the hexane losses from oilseed processing and refining, BAT is to use all of the techniques given below.\nTechnique\nDescription\n(a)\nCountercurrent flow of meal and steam in the desolventiser-toaster\nHexane is removed from the hexane-laden meal in a desolventiser-toaster, involving a countercurrent flow of steam and meal.\n(b)\nEvaporation from the oil/hexane mixture\nHexane is removed from the oil/hexane mixture using evaporators. The vapours from the desolventiser-toaster (steam/hexane mixture) are used to provide thermal energy in the first stage of the evaporation.\n(c)\nCondensation in combination with a mineral oil wet scrubber\nHexane vapours are cooled to below their dew point so that they condense. Uncondensed hexane is absorbed in a scrubber using mineral oil as a scrubbing liquid for subsequent recovery.\n(d)\nGravitational phase separation in combination with distillation\nUndissolved hexane is separated from the aqueous phase by means of a gravitational phase separator. Any residual hexane is distilled off by heating the aqueous phase to approximately 80-95 °C.\nTable 22\nBAT-associated emission levels (BAT-AELs) for hexane losses from oilseed processing and refining\nParameter\nType of seeds or beans processed\nUnit\nBAT-AEL(yearly average)\nHexane losses\nSoybeans\nkg/tonne of seeds or beans processed\n0,3-0,55\nRapeseeds and sunflower seeds\n0,2-0,7",
