  • Processes for recovering oligomers of glycols and polymerization catalysts from waste streams
    Publication number: 20040211729
    Abstract: Processes for recovering oligomers and polymerization catalyst from aqueous waste streams generated during the production of polyalkylene ether glycols are provided. The processes utilize membranes, preferably reverse osmosis or nanofilter membranes. The processes can reduce waste and costs associated with the polymerization of polyalkylene ether glycols by recovery and recycling of glycols and catalysts.
