Embodiment 1

[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.

Embodiment 2

[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.

Abstract

This invention relates to methods for treating distillates obtained during the process of deodorizing various oils. More particularly, this invention relates to methods for recovering fatty acids, tocopherols, and sterols from a distillate obtained from the deodorizing of various oils.

Description

technical field [0001] The present invention relates to a process for treating fractions obtained during deodorization of different oils. More specifically, the present invention relates to a process for the recovery of fatty acids, tocopherols and sterols from fractions obtained by deodorizing various oils. Background technique [0002] Oils derived from plants and animals are valuable sources of fatty acids, tocopherols and sterols. But during the refining of such oils, depending on the chosen refining method, significant amounts of such components, especially tocopherols and sterols, are lost in various intermediate by-products and waste streams, including acidified soap stocks, deodorant fractions or both. Therefore, a large number of methods have been proposed for the recovery of fatty acids, tocopherols and sterols from different refining intermediates including high temperature distillation steps (commonly known as deodorization) in the production of oils and fats. ...
