Methods for treating deodorizer distillate

[0043] The evaporated fraction at about 300°F from the deodorization of organically extracted soybean oil flows at a flow rate of 250,000 lbs. Operate under pressure. The deodorant fraction contains about 50% by weight fatty acids, about 12% by weight tocopherols, about 14% by weight sterols, and about 24% by weight other components including oils.

[0044] The scrubbers consisted of cylindrical columns 14 feet high and 42 inches in diameter. The first enrichment zone is about 4 feet high and includes a fill zone with a vertical dimension of 15 inches. The packing zone within the first concentration zone contains a plurality of closely spaced serrated stainless steel discs provided with a plurality of holes. The nozzles extend into the first concentration zone above the fill zone. Vacuum is provided to the scrubber by Nash-kinema three-stage vacuum system or vacuum pump.

[0054] The evaporated fraction at a temperature of about 330°F from the deodorization of conventionally refined soybean oil flows into the first enrichment zone of a scrubber at a flow rate of 250,000 lbs. Operate under the pressure of Hg. The deodorant fraction contains about 45% by weight fatty acids, about 15% by weight tocopherols, about 20% by weight sterols, and about 20% by weight other components including oils.

[0055] The scrubber consists of a cylindrical tower 18 feet high and 60 inches in diameter. The first enrichment zone is about 5 feet high and includes a fill zone with a vertical dimension of 24 inches. The packing zone in the first concentration zone contains a plurality of closely spaced serrated stainless steel discs with a plurality of holes. The nozzles extend into the first concentration zone above the fill zone. Vacuum is provided to the scrubber by Nash-kinema three-stage vacuum system or vacuum pump.
