Publication number: 20130018197Abstract: The present invention provides certain improvements in methods for processing vegetable oils and apparatus for carrying out such methods. One embodiment provides a method for processing a partially processed oil including glycerides and a volatilizable impurity fraction. The partially processed oil may processed by driving off a first volatiles stream comprising a portion of the glycerides and at least a portion of the volatilizable impurity fraction, leaving a deodorized oil. The first volatiles stream may be introduced into a first condensing chamber and a glyceride-rich, impurity-poor first condensate may be condensed from the first volatiles stream, leaving a glyceride-poor, impurity-rich second volatiles stream. The second volatiles stream may be passed into a second condensing chamber and a glyceride-poor, impurity-rich second condensate may be condensed from the second volatiles stream.Type: ApplicationFiled: July 18, 2012Publication date: January 17, 2013Applicant: Cargill, IncorporatedInventor: Marco KRUIDENBERG

Patent number: 7597783Abstract: Methods for processing oils and apparatus for carrying out such methods are disclosed herein. One embodiment provides a method for processing a partially processed oil, wherein the oil includes glycerides and a volatilizable impurity fraction. The partially processed oil may be processed by driving off a first volatiles stream having a portion of the glycerides and at least a portion of the volatilizable impurity fraction, leaving a deodorized oil. The first volatiles stream may be introduced into a first condensing chamber and a glyceride-rich, impurity-poor fraction may be condensed from the first volatiles stream, leaving a glyceride-poor, impurity-rich second volatiles stream. The second volatiles stream may be passed into a second condensing chamber and a glyceride-poor, impurity-rich second condensate may be condensed from the second volatiles stream.Type: GrantFiled: November 13, 2001Date of Patent: October 6, 2009Assignee: Cargill, IncorporatedInventor: Marco Kruidenberg

Patent number: 7585990Abstract: The present disclosure provides low trans-fatty acid fat compositions, methods of hydrogenating unsaturated feedstocks (e.g., oils), and hydrogenation catalyst compositions. One exemplary method involves producing an activated catalyst composition by heating a nickel-based catalyst to a first temperature of at least about 100° C. in the presence of hydrogen and a fat component. An unsaturated feedstock may be contacted with the activated catalyst composition and hydrogenated by sustaining a hydrogenation reaction at a second temperature of no greater than about 70° C. Some specific implementations of the invention permit the production of partially hydrogenated seed oils with low trans-fatty acid contents.Type: GrantFiled: December 31, 2003Date of Patent: September 8, 2009Assignee: Cargill, IncorporatedInventors: Hans van Toor, Gijsbertus Johannes van Rossum, Marco Kruidenberg

Publication number: 20070185340Abstract: This disclosure describes select low trans-fatty acid fats and fat compositions and methods of making such fats and fat compositions. These fats and fat compositions achieve properties commonly associated with typical partially hydrogenated fats, but avoid the high trans-fatty acid contents typically associated with such fats.Type: ApplicationFiled: August 2, 2004Publication date: August 9, 2007Applicant: Cargill, IncorporatedInventors: N. Van Toor, Gijsbertus Van Rossum, Marco Kruidenberg

Publication number: 20070179305Abstract: The present disclosure provides low trans-fatty acid fat compositions, methods of hydrogenating unsaturated feed-stocks (e.g., oils), and hydrogenation catalyst compositions. One exemplary method involves producing a catalyst composition by heating a nickel-based catalyst to a first temperature of at least about 85° C. in the presence of hydrogen and a fat component. An unsaturated feedstock may be contacted with the catalyst composition and hydrogenated by sustaining a hydrogenation reaction at a second temperature of no greater than about 70° C. Some specific implementations of the invention permit the production of partially hydrogenated seed oils with low trans-fatty acid contents.Type: ApplicationFiled: July 30, 2004Publication date: August 2, 2007Applicant: Cargill, IncorporatedInventors: N.
