Regarding the selection of PH electrodes in exhaust gas treatment units
Thread Content
Seeking advice regarding natural gas exhaust treatment units, specifically on the selection of pH electrodes for exhaust gas absorption towers. The main process medium is acidic water containing H2S, and it is necessary to maintain a pH level of 6–8. Which manufacturer’s pH electrode and transmitter model should be chosen?
For wastewater or chemical fluids with high sulfur compound contents, when selecting a glass electrode for pH measurement, it is particularly important to avoid using ordinary pH electrodes; instead, an electrode system capable of withstanding contamination should be chosen. Manufacturers should preferably be well-known brands, as they offer a wide range of products, and their research on applications is certainly more thorough and comprehensive than that of some smaller companies.
