  • Chemical Regeneration of Activated Carbon
    Publication number: 20080286193
    Abstract: A simple, economical process is disclosed for regenerating granular activated carbon, using a combination of alcohol, alkali, and oxidant, preferably ethanol, sodium hydroxide, and hydrogen peroxide. The regeneration process employs inexpensive compounds, is well-suited to be implemented on-site, and does not require spent carbon to be transported to a specialized facility for regeneration. The need for thermal regeneration of carbon, and its high energy consumption, are avoided.

  • Direct production of white sugar from sugarcane juice or sugar beet juice
    Patent number: 7226511
    Abstract: An economical process is disclosed for the direct production of white sugar from clarified juice. Juice from a cane sugar mill, or sugar beet juice, is first contacted with hydrogen peroxide, before passing through granular activated carbon. The juice is then passed through cationic and anionic resins to remove inorganic compounds, colorants, and other impurities. Then the juice may be concentrated and sugar crystallized. White sugar is produced directly, without the need for an intermediate raw sugar crystallization.

  • Continuous pan crystallizer
    Patent number: 4816076
    Abstract: A continuous pan crystallizer, which is conventional in that it has a number of compartments, has cross-over ports through which massecuite passes from compartment to compartment just above heating tubes in the compartments. The cross-over ports have baffles on both sides to avoid short-circuiting or bypass of massecuite from one compartment to another.
