Publication number: 20130193036Abstract: Process and apparatus are described for adsorptive bubble separation of hydrophobic particles from liquid dispersions. When a gas-liquid-particle dispersion is introduced into a separation vessel, a baffle directs the rising bubbles toward the perimeter of the apparatus. At the liquid surface, bubbles with attached hydrophobic materials form a floating froth layer, which is directed toward a froth collection launder. Also disclosed is an improvement for froth flotation processes comprising using a vacuum to pull froth and/or collapsed froth into and through the froth collection launder and froth drain line.Type: ApplicationFiled: July 27, 2012Publication date: August 1, 2013Applicants: RENEWABLE ALGAL ENERGY, LLC, EASTMAN CHEMICAL COMPANYInventors: Robert L.

Patent number: 8251228Abstract: Process and apparatus are described for adsorptive bubble separation of hydrophobic particles from liquid dispersions. The process may be used to treat the gas/liquid dispersion after it has been introduced from two or more ducts near the perimeter or from a central duct of the separation vessel. When the gas-liquid-particle dispersion is introduced from a central duct, the rising bubbles are directed by, e.g., a baffle toward the perimeter of the apparatus, where they rise. At the liquid surface, bubbles with attached hydrophobic materials form a floating froth layer, which is directed toward a central froth collection launder. Rising froth at the perimeter pushing the froth bed into the reduced area of the center encourages further coalescence of the bubbles and increases liquid drainage from the froth, thus leading to concentration of the collected materials without the need for complex equipment geometry.Type: GrantFiled: June 18, 2008Date of Patent: August 28, 2012Assignees: Renewable Algal Energy, LLC, Eastman Chemical CompanyInventors: Robert L.

Publication number: 20120216321Abstract: The present invention is concerned with Capsicum plants producing greater than about 0.4% zeaxanthin, by weight in the dried, ripe fruit pod flesh, which plants have been developed from commercially grown Capsicum cultivars by plant breeding techniques. Zeaxanthin is the dominant carotenoid in the dried ripe fruit pod flesh, when measured in non-esterified forms. Alternatively, these plants may be characterized as exhibiting a high pigmentation measured as an ASTA value and further characterized by the predominant presence of zeaxanthin. The zeaxanthin derived from these Capsicum plants can be used in applications that include nutritional supplements, foods, functional foods, cosmetics, animal feeds, aquaculture feeds, and pharmaceuticals.Type: ApplicationFiled: April 30, 2012Publication date: August 23, 2012Applicant: KALAMAZOO HOLDINGS, INC.Inventors: Paul H.

Patent number: 8196750Abstract: A method of concentrating particles in a liquid-particle dispersion feed by adsorptive bubble separation by intimately contacting a gas with a pressurized stream of liquid in a chamber to form an aerated dispersion that retains at least some of the kinetic energy from the pressurized stream, and removing at least some of the kinetic energy from the aerated dispersion to form a dense foam. A liquid-particle dispersion feed is then injected into the dense foam to form a gas-liquid-particle dispersion. The gas-liquid-particle dispersion is injected into a flotation chamber at a point below a surface of a liquid contained therein, where the gas-liquid-particle dispersion forms bubbles of a gas-particle agglomerate, and the bubbles are released from the feed liquid depleted in hydrophobic particles and rise to the surface to form a floating froth enriched in particles.Type: GrantFiled: June 18, 2008Date of Patent: June 12, 2012Assignees: Renewable Algal Energy, LLC, Eastman Chemical CompanyInventors: Jeffrey S.

Patent number: 5959162Abstract: This invention pertains, firstly, to the use of mixtures of hydriodic acid and organic solvent soluble iodide salts as catalysts for the hydration of .gamma.,.delta.-epoxyalkenes to form a mixture of the corresponding 2-alkene-1,4-diol and 3-alkene-1,2-diol isomers. Secondly, this invention describes the use of pH to control the 2-alkene-1,4-diol/3-alkene-1,2-diol product ratio, and achieve improved 2-alkene-1,4-diol selectivities by controlling the pH to near neutral values. Thirdly, this invention includes a catalyst recovery process whereby a liquid/liquid extraction is used to separate the product from the catalyst. In this extraction, .gamma.,.delta.-epoxyalkene, or a .gamma.,.delta.-epoxyalkene-containing organic solvent, is used to extract the catalysts from water, leaving the diol products in the aqueous phase, from which they may be subsequently recovered by distillation, extraction or by other means.Type: GrantFiled: July 8, 1997Date of Patent: September 28, 1999Assignee: Eastman Chemical CompanyInventors: Peter B.
