Overview:

Electrolysis plants create hydrogen and chlorine from a brine solution. Chlorine gas generated from the anolyte of the electrolysis tank generally contains between 0.5 to 2.0 vol% H2O. The sample is then cooled and filtered to remove brine, subsequently coming out as wet chlorine gas. The wet gas is sent to a drying tower where it is treated with sulfuric acid to get moisture down to the ppm level.

Overview:

NH3 injection lowers NOx in stack flue gas, boosts dust collection efficiency, and prevents erosion. Precise measurement and control of NH3 are crucial to avoid excess use, which increases costs and causes odors. The TDLS8000 solves these issues with direct measurement for effective NH3 management.

Overview:

O2 measurement is used to safely recover flue gas containing a high concentration of CO from a converter furnace. With conventional paramagnetic oxygen analyzers, O2 concentrations are obtained through a sampling system to recovery flue gas. Therefore, there are problems with the maintenance and running costs of the sampling system, and time delays in measurement.
