  • Apparatus and method for concentrating corrosive liquids
    Patent number: 12290767
    Abstract: The invention relates to an apparatus for the continuous concentration of corrosive liquids, the apparatus comprising a fluid system with a regenerative heat exchanger for preheating the dilute liquid and a vapour line to supply solvent vapour, which has been separated from the heated liquid in a main separator, to the hot side of the regenerative heat exchanger as a heat source. The invention further relates to a method for continuously concentrating corrosive liquids, wherein the system pressure is greater than 1 bar.

  • Crystallizer or reactor and method for continuously growing crystals or continuously managing a reaction
    Patent number: 10661198
    Abstract: The invention relates to a processing device in the form of a crystallizer or reactor comprising a tube, at the opposite end regions of which an inlet and an outlet are provided for a crystallization or reaction medium. A helixical web is provided which runs about a longitudinal axis of the tube and which rests against the inner face of the tube casing, and the web is mounted so as to be rotatable about the aforementioned longitudinal axis of the tube. The device also has a drive for rotating the web.

  • Substrate-integrated hollow waveguide sensors
    Patent number: 10408725
    Abstract: Methods and apparatuses are provided that greatly expand the utility of conventional hollow waveguide-based sensors via either straight, substrate-integrated channels or via meandering (e.g., circuitous, curved or folded optical paths) waveguide sensor designs. Full- or hybrid-integration of the meandering hollow waveguide with light source, detector, and light-guiding optics facilitates compact yet high-performance gas/vapor and/or liquid sensors of the substrate-integrated hollow waveguide sensor.
