  • Patent number: 9315404
    Abstract: A process comprising contacting deionized water with one or more Strecker sulfonation reaction products of one or more halogenated alkyl ethers in the presence of sulfite, wherein the one or more Strecker sulfonation reaction products each comprise one or more inorganic salts on a dry basis and one or more surfactant components, form a filtration mixture; loading the filtration mixture into a high pressure filtration system containing a membrane having a membrane molecular weight cutoff allowing preferential passage of the inorganic salts, for example, of greater than or equal to 200 Daltons; wherein the high pressure filtration system is operated at a pressure greater than ambient pressure and is configured to cause crossflow of the filtration mixture along a surface of the membrane resulting in a permeate solution which substantially passes through the membrane and a retentate solution which substantially does not pass through the membrane; wherein the permeate comprises less than or equal to 15 weight perc

  • Patent number: 9180384
    Abstract: Disclosed are a process and an apparatus for using an olefin as an azeotropic entrainer to isolate a target organic compound from a waste stream. The olefin may be, for example, 1-decene, 1-dodecene, or 1-tetradecene. The target organic compound may be 1,3-dichloro-2-propanol in waste stream comprising a 2,2?-oxybis(1-chloropropane).
