Deriving optimum hydrochloric acid from the biological waste gas treatment
Krems Chemie Chemical Services AG, a chemical company in the Wachau valley, Austria manufacturers halogen-free flame retardants and intermediates for a diverse range of applications. The Valmet Concentration Measurement units are installed in the biological waste gas treatment plant.
|Location||Wachau valley, Austria|
|Customer challenge||Krems Chemie upgraded and expanded their production facilities for fireproofing materials. Halogene-free flame retardants are produced by reaction between phosphorus trichloride and orthophenyl phenol with zinc chloride as catalyst. Beside the halogene-free flame retardants, hydrochloric acid is produced as waste gas. Gaseous hydrochloric acid as a by-product in the process is derived by biological treatment of the waste gas.|
In order to measure and control the gas scrubber, two Series 3300 Valmet Concentration Measurements units were installed to show the exact Hydrochloric acid in %.
The unique corrosion resistant sensors perform high accuracy measurements based on the 4-electrode measuring principle, and the design provides for high
