  • MULTIPLE MEMBRANES FOR REMOVING VOC'S FROM LIQUIDS
    Publication number: 20140073718
    Abstract: The present invention relates to a process for removing volatile organic compounds (VOCs) from a liquid stream using multiple membranes that are permeable to the VOCs but impermeable to the liquid.
    Type: Application
    Filed: September 4, 2013
    Publication date: March 13, 2014
    Applicants: ROHM AND HAAS COMPANY, DOW GLOBAL TECHNOLOGIES LLC
    Inventors: James Kent Carpenter, Timothy C. Frank
  • Process for stripping polymer dispersions
    Patent number: 7745567
    Abstract: A process for continuously stripping a polymer dispersion comprising a heat exchanger with minimal internal obstructions for the stripper. The process is particularly adapted to dispersions that are heat and shear sensitive. The process is able to extract hydrophobic VOC's more efficiently than a single, jacketed tube design.
    Type: Grant
    Filed: October 29, 2007
    Date of Patent: June 29, 2010
    Assignee: Rohm and Haas Company
    Inventors: James Kent Carpenter, Adam Loyack
  • Steam stripping polymer dispersions to improve biocide stability
    Publication number: 20090082409
    Abstract: A process for stabilizing biocide compounds in a polymer dispersion requiring stripping of the dispersion using steam or an inert gas.
    Type: Application
    Filed: September 10, 2008

  • Process for cleaning reactors
    Publication number: 20040255980
    Abstract: This invention relates to a process for cleaning reactors. The process utilizes a solvent fed from multiple pressure sources to clean reactors of residual polymers. The reactors are equipped with agitators and stationary nozzles aimed at the agitator blades. The agitator is rotated during cleaning. The process may also utilize heated aqueous base to clean heat exchangers in external loops. In one aspect, a mixture of at least one organic solvent and aqueous base are utilized to clean certain reactors.
