The present invention generally provides a process for treating a soapstock. The present invention more particularly provides systems and methods for treating a soapstock to generate free fatty acids and/or fatty acid derivatives, e.g. fatty acid alkyl esters. The present invention more particularly provides systems and methods for realizing the full fatty acid yield of a soapstock by first converting substantially all of the saponifiable material in a soapstock to salts of fatty acids (soaps) and acidulating the soaps to generate free fatty acids and/or fatty acid derivatives, e.g. fatty acid alkyl esters, wherein the soapstock comprises soaps and saponifiable lipids, e.g. glycerides and/or phospholipids, and the generating of free fatty acids and/or fatty acid is achieved without the use of a mineral acid.

Embodiments of the present invention provide a method, comprising obtaining a lecithin-containing material, in some aspects derived from a crude refining stream, comprising 20-80 wt % acetone insoluble matter, 1-30 wt % free fatty acid, and less than 10 wt % water, adding a fatty acid or carboxylic source to the lecithin-containing material to obtain a lecithin fatty acid blend or lecithin carboxylic acid blend and incorporating the blend into asphalt or oil field applications.

Products produced from distillers corn oil include once refined corn oil product, food grade corn oil product, and free fatty acid product which may be used in a variety of applications. The products have varying specifications for free fatty acid content and moisture content. The applications include food, feed, additives, and manufacture of industrial products.

The present invention relates to a method for recovering crude tall oil from a soap which method comprises the steps of: determining a correlation between the crude tall oil content and the water content of the soap, determining an amount of acid and water needed in order to separate an optimal amount of crude tall oil from the soap dependent on the crude tall oil content of the soap, measuring the water content of the soap, adding the optimal amount of acid and water to the soap, mixing the added acid and water with the soap whereby an acidulated soap is formed and the crude tall oil is separated and recovering the separated crude tall oil from the acidulated soap.

Disclosed is a method for preparing bio-oil, which can be used as bio heavy fuel oil and bio marine oil, from a fatty acid with high acid value. The method for preparing bio-oil comprises the steps of: inputting materials comprising glycerine and a fatty acid into respective material input ports positioned in the center of a column-type reactor and esterification reacting the material comprising glycerine and fatty acid in each tray of a reaction area, thereby producing glyceride and water; obtaining the produced glyceride through a lower part of the reactor; and vaporizing the water produced by the reaction, moving the water (vapor) to a distillation area in an upper part of the reactor to separate the water from active components comprised in the vapor, allowing the separated active components to flow into the reaction area, and removing the separated water (vapor) through the upper part of the reactor.
