20090023902 | Method for the extraction of intracellular proteins from a fermentation broth - A method for extracting an intracellular peptide, protein or other polypeptide from a whole fermentation broth using a water miscible alcohol, or a water miscible or partially water miscible glycol ether. | 01-22-2009 |
20090321352 | LIQUID-LIQUID EXTRACTION - A liquid-liquid extraction process that uses counterflowing liquid phases, especially in conjunction with a reciprocating plate extraction column, wherein one of the liquid phases has a lower density than the other and is at least partially saturated with a dispersible gas, requires less plate stack height or a smaller column diameter when plate-to-plate spacing is non-uniform rather than uniform and such non-uniform plate-to-plate spacing includes greater plate-to-plate spacing proximate to raffinate liquid discharge than proximate to feed of the lower density liquid phase. | 12-31-2009 |
20100099155 | RECOVERY OF VOLATILE PRODUCTS FROM FERMENTATION BROTH - Provided are apparatuses and processes for the removal and purification of fermentation prepared one or more volatile organic compounds. The apparatuses comprise a fermentor unit, a vacuum side stripper unit ( | 04-22-2010 |
20110005914 | Selective dehydrohalogenation of tertiary halogenated hydrocarbons and removal of tertiary halogenated hydrocarbon impurities from a halogenated hydrocarbon product - A process for converting a tertiary halogenated hydrocarbons in a tertiary halogenated hydrocarbon-containing stream to a corresponding unhalogenated or less-halogenated unsaturated hydrocarbon product with the release of hydrogen halide involves contacting the tertiary halogenated hydrocarbon with a sorbent-type dehydrohalogenation catalyst in a reaction zone and optionally passing a stripping gas through the reaction zone to remove vapor phase reaction products from the reaction zone. A process for removing a tertiary chlorinated hydrocarbon impurity from 1,3-dichloro-1-propene involves contacting a mixture containing the 1,3-dichloro-1-propene and the tertiary chlorinated hydrocarbon impurity with a dehydrochlorination catalyst effective to catalyze a conversion of the tertiary chlorinated hydrocarbon impurity to a corresponding unchlorinated or less-chlorinated unsaturated hydrocarbon and hydrogen chloride and distilling the 1,3-dichloro-1-propene to produce a purified cis-1,3-dichloro-1-propene fraction and a purified trans-1,3-dichloro-1-propene fraction. | 01-13-2011 |
20110031102 | PURIFICATION OF HYDROFORMYLATED AND HYDROGENATED FATTY ALKYL ESTER COMPOSITIONS - Effect separation of a composition of matter that includes at least two seed or plant oil derivatives into at least one desired product stream using at least two separation operations, which are independently selected from among several potential separation operations, in conjunction with at least one recycle stream from a separation operation. | 02-10-2011 |
20130206578 | SELECTIVE DEHYDROHALOGENATION OF TERTIARY HALOGENATED HYDROCARBONS AND REMOVAL OF TERTIARY HALOGENATED HYDROCARBON IMPURITIES FROM A HALOGENATED HYDROCARBON PRODUCT - A process for converting a tertiary halogenated hydrocarbons in a tertiary halogenated hydrocarbon-containing stream to a corresponding unhalogenated or less-halogenated unsaturated hydrocarbon product with the release of hydrogen halide involves contacting the tertiary halogenated hydrocarbon with a sorbent-type dehydrohalogenation catalyst in a reaction zone and optionally passing a stripping gas through the reaction zone to remove vapor phase reaction products from the reaction zone. A process for removing a tertiary chlorinated hydrocarbon impurity from 1,3-dichloro-1-propene involves contacting a mixture containing the 1,3-dichloro--propene and the tertiary chlorinated hydrocarbon impurity with a dehydrochlorination catalyst effective to catalyze a conversion of the tertiary chlorinated hydrocarbon impurity to a corresponding unchlorinated or less-chlorinated unsaturated hydrocarbon and hydrogen chloride and distilling the 1,3-dichloro-1-propene to produce a purified cis-1,3-dichloro- 1-propene fraction and a purified trans-1,3-dichloro-1-propene fraction. | 08-15-2013 |
20130206579 | SELECTIVE DEHYDROHALOGENATION OF TERTIARY HALOGENATED HYDROCARBONS AND REMOVAL OF TERTIARY HALOGENATED HYDROCARBON IMPURITIES FROM A HALOGENATED HYDROCARBON PRODUCT - A process for converting a tertiary halogenated hydrocarbons in a tertiary halogenated hydrocarbon-containing stream to a corresponding unhalogenated or less-halogenated unsaturated hydrocarbon product with the release of hydrogen halide involves contacting the tertiary halogenated hydrocarbon with a sorbent-type dehydrohalogenation catalyst in a reaction zone and optionally passing a stripping gas through the reaction zone to remove vapor phase reaction products from the reaction zone.
