  • Patent number: 11204111
    Abstract: A pipe, the inner surface of which is lined with a thermoplastic layer, is produced by a process comprising the following steps: a) a metal pipe is provided, b) a tubular inliner composed of a thermoplastic material is provided, c) a tape is cohesively helically bonded to the inliner, wherein the region of the contact surface of the tape consists of a moulding composition or an adhesive which adhere firmly to the surface of the inliner, and wherein the region of the opposing surface of the tape consists of a moulding composition or an adhesive which adhere firmly to the metal of the pipe, wherein the tape contains unidirectional reinforcing fibers; d) the cross section of the inliner is optionally reduced by exposure to an external force, e) the inliner is inserted into the metal pipe, f) by means of contact pressure and optionally heat, the inliner and metal pipe are firmly bonded to each other.

  • Patent number: 10071951
    Abstract: The present application relates to a process for removing an organic compound having one or more positive charges from an aqueous solution, comprising the steps a) provision of the aqueous solution comprising the organic compound and of a hydrophobic organic solution which comprises a liquid cation exchanger, where the liquid cation exchanger is hydrophobic, and where the liquid cation exchanger has one or more negative charges and an overall negative charge, b) contacting the aqueous solution and the organic solution, and c) separating off the organic solution from the aqueous solution.

  • Patent number: 9382181
    Abstract: A process for removing a cyclododecanone-rich target fraction (A) from a dehydrogenation mixture (O) comprising low boilers (LB), cyclododecanone (CDON), medium boilers (MB), cyclododecanol (CDOL) and high boilers (HB) is provided. According to the process, substantially pure CDON is obtained via a distillative sequence of two side draw columns connected in series, wherein the sidestream of the primary side draw column is fed into the secondary side draw column. From the top of each of the two side draw columns, a CDON-rich fraction is drawn off, and these are combined to form a target fraction, which is essentially pure CDON.

  • Patent number: 9278898
    Abstract: A process for removing a cyclododecanone-rich fraction from a dehydrogenation mixture containing low boilers, cyclododecanone, medium boilers, cyclododecanol and high boilers is provided. According to the process, the cyclododecanone is separated from the cyclododecanol in a dividing wall column. The apparatus which is the dividing wall column is also provided within this invention.
