摘要： Methods for producing oil from distillers corn oil having high free fatty acid content are provided. In the method, distiller's corn oil is treated with a mixture including an alcohol to result in a low-free fatty acid oily phase and an alcohol phase. The mixture may also include an alkali. The alcohol may be a monohydric alcohol and an aqueous alcohol, such as an aqueous alcohol having a concentration of at least about 15% alcohol-by-weight. The low-free fatty acid phase may include oil and at least one impurity. The low-free fatty acid phase may be cooled, and the oil may be separated from the at least one impurity using membrane filtration.

摘要： Methods for producing oil from fats and oils having high free fatty acid content are provided. In the method, fats and oils are treated with a mixture including an alcohol to result in a low-free fatty acid oily phase and an alcohol phase. The mixture may also include an alkali. The alcohol may be a monohydric alcohol and an aqueous alcohol, such as an aqueous alcohol having a concentration of at least about 15% alcohol-by-weight. The low-free fatty acid phase may include oil and at least one impurity. The low-free fatty acid phase may be cooled, and the oil may be separated from the at least one impurity. Fats and oils amenable to such a method may include, but are not limited to, waste fats, waste oils, high acid grease, high acid tallow, sorghum wheat oil, and corn oil, such as corn oil produced at an ethanol production plant.

摘要： 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.

摘要： Provided are methods to destabilize emulsion feedstocks. Benefits of the provided methods include a reducing or eliminating the amount of acid necessary to process the feedstocks, less processing time, cleaner separation of the resulting phases, and increased recovery of valuable products. In the methods, a moderate temperature is applied to the feedstock to create a first mixture. The moderate temperature may be between 120 and 220 degrees Celsius. The first mixture is mixed at the moderate temperature, such as by staged mixing in some embodiments. Moreover, the first mixture is retained at the moderate temperature for up to six hours. The first mixture is separated into an oil phase, convoluted phase, and a water phase. In some embodiments, the moderate temperature may be 125 to 150 degrees Celsius, such as between 125 and 130 degrees Celsius. Moreover, the first mixture may be retained at the moderate temperature for between forty-five minutes and four hours, such as from two to four hours. The separation may occur at the moderate temperature.

摘要： A method and arrangement for separating tall oil products from a black liquor-containing boiling liquid that has been drained off, was produced within a kraft mill chip digester, and includes a fibrous cellulose material in a mixture with the black liquor and tall oil products, and where the boiling liquid is separated in a separation unit arranged to mechanically separate the boiling liquid into a fibrous cellulose material and a mixture of mixed black liquor and tall oil products, where the mixture of boiling liquid and tall oil products is brought to a separation tank, the separation tank being a gravity separation tank, and adapted to be emptied in a discontinuous manner of the tall oil product collected and concentrated therein, the tall oil products being floated on top of and above a fraction of mixed black liquor, where the tall oil products is brought to a centrifugal separator.

摘要： A process for the recovery of fatty acids from discarded solid soap material comprises the steps of:(a) stirring discarded solid soap material into a melt of one or more fatty acids at the melting temperature of the discarded soap which is usually from about 40.degree. C. to about 180.degree. C. until the soap material has dissolved in the fatty acid melt;(b) adding to the thus-produced solution of soap material in the fatty acid melt an amount of an undiluted acid sufficient to convert the soap material to free fatty acid and form one or more alkali metal salts, and heating and stirring at about 40.degree. C. to about 180.degree. C. to produce free fatty acid and one or more alkali metal salts;(c) separating the freed fatty acid in the fatty acid melt from the thus-produced salt of one or more alkali metals; and(d) refining freed fatty acids using filtration, distillation, decolorization, deodorization, etc.It is preferred that the lower melt temperatures be utilized to avoid discoloration, but time requirements dictated by the varying composition of the soap may make the use of the more elevated temperatures expedient.
