A process for providing hydrogenated oils and/or fats involves providing a fat fraction and/or oil fraction having a phosphorus content of more than 3.0 mg/kg and/or a total metal content of more than 5.0 mg/kg. The fat fraction and/or oil fraction is washed with an organic acid and optionally a demulsifier by stirring to form a heterogeneous mixture. The mixture is centrifugally separated to form a high-water and low-oil and/or -fat phase and a low-water and high-oil and/or -fat phase having a phosphorus content of less than 3.0 mg/kg and a total metal content of less than 5.0 mg/kg. The low-water and high-oil and/or -fat phase is dried. The dried high-oil and/or -fat phase is catalytically hydrogenated. The proportion of water metered in during the performance of the process is less than 5% by weight, based on the weight of the fat fraction and/or oil fraction.

A chemical additive for reclaiming oil from a fluid product stream is described. In embodiments, chemical additive compositions comprise a propylene glycol ester, a hydrophobic silica, a polyglycol ester or a polyglycerol oleate ester, a polyethoxylate sorbitan or sorbitan ester and a block copolymer or ethylene oxide-propylene oxide polymer. Less chemical additive is needed for improved oil extraction and concentration and a shorter incubation time is required, which reduces cycle time and energy consumption.

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.

Methods are provided for refining natural oil feedstocks. The methods comprise reacting the feedstock in the presence of a metathesis catalyst under conditions sufficient to form a metathesized product comprising olefins and esters. In certain embodiments, the methods further comprise separating the olefins from the esters in the metathesized product. In certain embodiments, the methods further comprise hydrogenating the olefins under conditions sufficient to form a fuel composition. In certain embodiments, the methods further comprise transesterifying the esters in the presence of an alcohol to form a transesterified product.
