A new method for monitoring H2
S in process and emission applications is now introduced. The method is using OPSIS Hot Wet Extractive system in combination with a new converter. With this converter, H2
S is converted into other substances that can easily be measured with OPSIS UV DOAS system. No SO2
scrubber is needed and the system can monitor all other relevant gases by using a separate optical path.
The method has used ambient air SO2
analysers and dilution extractive. Many of us has experienced application problems with these installations.
OPSIS is now introducing a new method for monitoring of H2
S. The OPSIS Hot Wet Extractive system
is used in combination with a new converter. H2
S is simply converted into other components that are easily measured with OPSIS UV DOAS. No scrubber is needed and the system can monitor all other gases using a separate optical path.
Besides monitoring H2
S, a single System 400HWE can measure other relevant gases for CEM applications such as NO, NO2
, CO, CO2
, HCl, HF, N2
, and Hg. OPSIS monitoring systems have been tested and approved
by a number of internationally recognized institutes and authorities.
