  • Patent number: 10859317
    Abstract: The present invention relates to an apparatus and a method for evaporating liquids containing potentially explosive impurities of lower volatility than the actual liquid compound. The set-up of the evaporator according to the invention allows its operation with complete evaporation of a liquid without formation of a liquid sump of not yet evaporated liquid.
    Type: Grant
    Filed: August 14, 2014
    Date of Patent: December 8, 2020
    Assignee: Covestro Deutschland AG
    Inventors: Alfred Soppe, Jiyuan Sun, Thorsten Leidig, Thomas Runowski, Dieter Heitkamp
  • Publication number: 20180186633
    Abstract: The present invention relates to a process for purifying raw-material gases by fractionation. In particular, the present invention relates to a process for cleansing chlorine gas of bromine.

  • Publication number: 20080053839
    Abstract: Processes are described which include: (a) providing an initial crude alkali metal chloride brine; (b) mixing the initial crude brine with a recirculated brine to form a process brine steam; (c) subjecting the process brine stream to electrolysis to form chlorine gas and an electrolyzed weak brine; and (d) subjecting the electrolyzed weak brine to a post-electrolysis salt enrichment comprising (i) diverting a substream of the electrolyzed weak brine at a post-electrolysis diversion point; (ii) removing water from the substream; (iii) crystallizing salt present in the substream; (iv) separating the crystallized salt from the substream; and (v) introducing the separated salt into the electrolyzed weak brine to form the recirculated brine.
