| 20110165302 | COMPOSITIONS AND PROCESSES FOR IMPROVING PHOSPHATATION CLARIFICATION OF SUGAR LIQUORS AND SYRUPS - A process for improving phosphatation clarification of sugars can include adding to a sugar liquor a composition having at least one particulate sulfur reagent and at least one or more other particulate solids selected from, a particulate phosphorous reagent, a particulate carbonaceous reagent, a particulate aluminum reagent, a particulate filter aid, and a particulate ammonium reagent. The composition can be added to the phosphatation chemical reaction tank or prior to the phosphatation chemical reaction tank. Phosphatation chemicals, for example polymer decolorant, phosphoric acid, lime and a flocculent, can be added into the process at least five minutes after adding the composition. In using the process, the amount of phosphatation chemicals added is less than the amount of phosphatation chemicals required in the absence of addition of the composition or the purity of the sugar is improved as measured by one or more of color, turbidity and ash. | 07-07-2011 |
| 20110165303 | COMPOSITIONS AND PROCESSES FOR IMPROVING CARBONATATION CLARIFICATION OF SUGAR LIQUORS AND SYRUPS - This invention relates to compositions and processes for improving the carbonatation clarification of sugar liquors and syrups. The improved processes involve adding compositions to a sugar liquor directly in the carbonated liquor holding tank (after the final carbonatation saturator), upstream of the carbonated liquor holding tank but downstream of the final stage Carbonatation saturator, before filtration of the carbonated liquor, or at any stage in the sugar purification process. The compositions provided in this invention are mixed intimately into the sugar liquors or syrups, and allowed sufficient time to react to impart an improvement in the clarified liquor obtained therefrom. Compositions can include combinations of one or more of a particulate sulfur reagent, particulate phosphorous reagent, particulate aluminum reagent, silica reagent, particulate carbonaceous reagent, particulate filter aid, a polymer decolorant, and particulate ammonium reagent. | 07-07-2011 |
