  • LIQUID AERATOR
    Publication number: 20120234394
    Abstract: The invention relates to a sparger for introducing a gas or gas mixture into a liquid and to a method for sparging liquids. The sparger according to the invention comprises a cavity, a gas inlet for routing a gas into the cavity and two or more faces, which are or can be pressed onto one another in a positive fashion such that a gas pressed into the cavity through the gas inlet escapes through the gaps occurring between the pressed together faces.

  • Process for the production of isocyanates in the gas phase
    Patent number: 6803482
    Abstract: Isocyanates are produced in the gas phase in a manner such that temperature fluctuations over time and temperature distribution asymmetry are prevented. In this improved process, performance of the reaction in tubular reactors is accomplished by flow-related measures such as homogenization and centering of the educt streams. The formation of polymeric secondary products, which result in baked-on deposits in the reactor and a reduction in reactor service life, is consequently prevented.
