  • Sweetener solution purification process
    Patent number: 4587953
    Abstract: An improved process for purifying sweetener solutions is described. This process features passing crude sweetener solution through a series of adsorption materials, preferably arranged in the following order; cation exchange resin, microporous adsorbent, anion exchange resin.
    Type: Grant
    Filed: September 4, 1984
    Date of Patent: May 13, 1986
    Assignee: Calgon Carbon Corporation
    Inventor: Michael R. Rosene
  • Process for dehydrating ethanol
    Patent number: 4465875
    Abstract: Aqueous ethanol and other lower alkanol water mixtures may be dehydrated in the gas or liquid phase by using carbon molecular sieves. These sieves preferentially adsorb water and recovery of absolute ethanol or other absolute alkanol is achieved. Absolute ethanol produced from this process may be used in the manufacture of gasohol.
    Type: Grant
    Filed: September 27, 1982
    Date of Patent: August 14, 1984
    Assignee: Calgon Carbon Corporation
    Inventors: Michael Greenbank, Michael R. Rosene
  • Glycol purification with minimal pH drop
    Patent number: 4398046
    Abstract: Standard activated carbons have been commonly employed in the purification of contaminated glycol scrubbing solutions used in a liquid-liquid extraction process for the manufacture of petrochemicals. These carbons are shown to cause a depression of pH within the glycol stream when a new carbon type is installed or when the exhausted carbon is replaced. The use of a magnesite containing activated carbon minimizes this pH drop to acceptable levels.
