  • Method for continuously determining the concentration of at least one CN compound in an aqueous solution
    Patent number: 8900873
    Abstract: The invention relates to a method for continuously determining the concentration of at least one CN compound in an aqueous solution, wherein a carrier gas, for example compressed air, is introduced into the aqueous solution and the introduced carrier gas is fed at least partially to a gas analyzer, for example an HCN gas analyzer, the analysis data of which are considered in the determination of the concentration of the CN compound in the aqueous solution. In order to create advantageous method conditions, the temperature of the aqueous solution exposed to carrier gas is considered in the determination of the concentration of the CN compound.

  • Method of separating solid and/or liquid particles and/or polluting gas from a gas stream, and apparatus for carrying out the method
    Patent number: 5427608
    Abstract: A method and apparatus for separating solid and/or liquid particles and/or polluting gas from a gas stream includes two component nozzles by which a washing liquid is finely distributed in a gaseous phase and introduced in the gas stream within a gas washer. The two-component nozzles are distributed over the whole cross section of the washer, preferably on a plane that extends perpendicularly to the gas flow direction.
