  • Process for producing water-absorbing polymer particles
    Patent number: 8828323
    Abstract: A process for producing water-absorbing polymer particles, wherein a polymer gel is removed from a polymerization reactor, stored intermediately as a particulate polymer gel in a delay vessel, removed by means of a first conveying device at the lower end of the delay vessel and dried, the intermediately stored particulate polymer gel being conveyed within the delay vessel by means of at least one second conveying device above the first conveying device in the direction of the first conveying device.
    Type: Grant
    Filed: November 2, 2012
    Date of Patent: September 9, 2014
    Assignee: BASF SE
    Inventors: Matthias Weismantel, Rüdiger Funk, Ann Becker, Leo Van Miert
  • Method for the continuous thermal secondary surface cross-linking of water-absorbing polymer particles
    Patent number: 8394895
    Abstract: A process for continuous thermal postcrosslinking of water-absorbing polymer particles, wherein the postcrosslinker is applied to the water-absorbing polymer particles by means of suitable nozzles and the nozzles are exchanged or cleaned via the interior of a glovebox adjoining the plant section comprising the nozzle.
