A process is provided for removing organic chlorides from glyceride oil. The process includes the steps of (a) reacting a glyceride oil comprising organic chlorides with a liquid aqueous system at a temperature of at least 80° C. to form a treated glyceride oil and (b) separating the treated glyceride oil from the liquid aqueous system. The treated glyceride oil has a reduced concentration of organic chlorides compared to the glyceride oil reacted in step (a).

The present invention relates to a process reducing in a palm oil the content of unwanted propanol components selected from free chloropropanols, chloropropanol fatty acid esters and combinations of two or more thereof, and the process is comprising a bleaching step using an adsorbent comprising alumina oxide wherein the content of alumina oxide is not more than 9.5%, preferably the adsorbent is having a content of earth alkali oxides of from 12 to 27%.

A method of extracting oil from biological raw material includes creating a slurry of biological raw material, raising or lowering a pH of the slurry to separate lipid and protein components in the slurry, further separating the lipid and protein components into a first lipid rich phase and a protein rich phase, adjusting a pH of the first lipid rich phase to a point at which additional proteins in the first lipid rich phase coagulate, and recovering a second lipid rich phase from the additional coagulated proteins.

A process and apparatus for recovering crude tall oil are disclosed. Acidulation of a crude tall oil soap stream generates a spent acid stream that comprises lignin and entrained crude tall oil. By subjecting the spent acid stream to dissolved gas flotation, a lignin phase comprising entrained crude tall oil can be recovered and causticized, resulting in recovery of most of the crude tall oil that was present in the spent acid stream. A clarified spent acid stream is also generated, which can be treated with caustic and utilized for a soap washing process that integrates easily into the overall CTO recovery process. The apparatus comprises a crude tall oil acidulation unit, a dissolved gas flotation unit, a causticizing unit, and a soap separation unit. The inventive process marries dissolved gas flotation, a well-known water treatment process, with causticization of a recovered lignin phase, a step known from batch acidulation, to improve overall tall oil recovery from a continuous process.
