The present invention is directed to a chloropropanol prevention pre-treatment process for crude vegetable oils.

A process for producing a chloride depleted feedstock from a chloride containing crude oil or fat feedstock is provided. The process including the following steps: providing the chloride containing crude oil or fat feedstock; contacting the chloride containing crude oil or fat feedstock with at least one degumming agent under degumming conditions to obtain a degummed feedstock; contacting the degummed feedstock with at least one first chloride removal agent under first chloride removal conditions to obtain a first dechlorinated feedstock; contacting the first dechlorinated feedstock with at least one bleaching agent under bleaching conditions to obtain a bleached feedstock; contacting the bleached feedstock with at least one second chloride removal agent under second chloride removal conditions to obtain a chloride depleted feedstock; and routing out the chloride depleted feedstock from a second chloride removal step.

A process for producing a pretreated oil or fat product from a crude oil or fat feedstock including a polymer, is provided. The process includes providing the crude oil or fat feedstock including a polymer from a storage volume; subjecting the crude oil or fat feedstock to a degumming step to obtain a degummed oil or fat feedstock; subjecting the degummed oil or fat feedstock to a bleaching step to obtain a bleached oil or fat feedstock; and routing out the bleached oil or fat feedstock from the bleaching step as the pretreated oil or fat product. The process also includes a polymer removal step, performed on the oil and fat feedstock upstream of any of the process steps (for producing polymer depleted oil or fat feedstock.

The present technology provides a method that includes contacting a composition with a caustic solution to produce a caustic-treated composition; combining the caustic-treated composition with silica particles to produce a slurry; and removing the silica particles from the slurry to produce a treated composition; wherein the composition includes one or more of animal fats, animal oils, plant fats, plant oils, vegetable fats, vegetable oils, greases, and used cooking oil and the composition includes: at least about 10 wppm of total metals, at least about 8 wppm of phosphorus, at least about 10 wppm of chlorine, at least about 10 wppm of sulfur, at least about 20 wppm of nitrogen, at least about 5 wt. % of free fatty acids; and has an acid number from about 10 mg KOH/g to about 150 mg KOH/g, and the silica particles has a particle size from about 10 microns to about 50 microns, a BET surface area from about 200 m.sup.2/g to about 1000 m.sup.2/g.

A system for purifying edible oils includes a plurality of microchannel fiber reactors arranged in series. The edible oils may be first neutralized with an alkali solution and then washed with water to thereby remove impurities such as free fatty acids, mono- and diacylglycerols, phospholipids, glycolipids, trace metals, and unsaponifiable matter. The system allows for continuous, high-yield production of improved quality edible oils.
