  • Patent number: 10344246
    Abstract: A system and method for degumming oil is used to increase oil yield and reduce impurities such as phosphorus. An oil feedstock, water and enzyme mixture is passed through a high shear mixing device prior to being fed to an agitated reactor equipped with a recirculation system. The recirculation system includes a second high shear mixing device that further mixes the oil mixture in the reactor during processing. The reacted mixture is discharged from the reactor to a downstream post-reaction system for separating the degummed oil from the reacted mixture. The separation step can be used to remove the phosphatides and other impurities from the reacted oil to form a purified oil product.

  • Patent number: 10053370
    Abstract: A method for obtaining particulate calcium carbonate exhibiting improved brightness and color and having uniformity of size such that when the particles are formed in the causticization process in a kraft pulp mill, the time required to separate the particles from liquors in which they are suspended is minimized and the amount of liquor recovered is maximized, with minimal dilution by water used for washing. The method includes the steps of a) slaking calcium oxide in water or an alkaline liquor containing as dissolved species predominantly sodium hydroxide; b) mixing the slaked lime with green liquor from a kraft pulping process to complete a causticization reaction that produces white liquor and lime mud; c) separating the lime mud from the white liquor; and d) milling a portion of the lime mud for use as a white mineral pigment in applications where such pigments are typically used.

  • Patent number: 9713788
    Abstract: A method is described for separating CO2 and/or H2S from a mixed gas stream by contacting the gas stream with a non-aqueous, liquid absorbent medium of a primary and/or secondary aliphatic amine, preferably in a non-aqueous, polar, aprotic solvent under conditions sufficient for sorption of at least some of the CO2. The solution containing the absorbed CO2 can then be treated to desorb the acid gas. The method is usually operated as a continuous cyclic sorption-desorption process, with the sorption being carried out in a sorption zone where a circulating stream of the liquid absorbent contacts the gas stream to form a CO2-rich sorbed solution, which is then cycled to a regeneration zone for desorption of the CO2 (advantageously at <100° C.). Upon CO2 release, the regenerated lean solution can be recycled to the sorption tower. CO2:(primary+secondary amine) adsorption molar ratios>0.5:1 (approaching 1:1) may be achieved.
