Abstract
<PICT:0640244/III/1> Tall oil is separated into a fatty acid fraction and a resin acid fraction by submitting the tall oil, preferably after removal of its low-boiling constituents, to fractionation under sub-atmospheric pressure. The main fatty acid fraction is withdrawn from the fractionation as a liquid side-stream; while the resin acid is withdrawn as liquid bottoms. Tall oil was fed through line 10 into heat exchanger 11, and then introduced into fractionating tower 13 which was connected through condenser 16 with a vacuum pump, and supplied with live steam through line 19. The top of the tower was maintained at 375 DEG F. and 35 mm.; the bottom at 475 DEG F. and 65 mm. The overhead vapours were condensed in condenser 16, and three-quarters of the condensate was returned to the tower as reflux. Tall oil free from low-boiling constituents, was withdrawn from tower 13 through line 20, and introduced into fractionating tower 21. The top of tower 21 was maintained at 375 DEG F. and 4 mm.; the bottom at 545 DEG F. and 40 mm. The overhead vapours taken off through line 25 were condensed in condenser 26, and a large percentage of the condensate (equivalent to a reflux ratio of 14) was returned to the tower. The main fatty acid product was taken off the fourth tray from the top of the tower, and was withdrawn through line 37. Resin acid was withdrawn from the base of tower 21 through line 29 and introduced into flash chamber 30 which was maintained at 550 DEG F. and 5 mm. The vapours from the flash chamber were condensed in condenser 32 to give the resin acid product. Both flash chamber 30 and tower 21 were supplied with small quantities of live steam.
