Online detection of acidic gases in sulfur recovery
Thread Content
The sulfur recovery acid gas contains 30% hydrogen sulfide; what instruments are available for online detection? It would be best if it’s already in use, so that I can draw on its applications. Thank you!
Are there flowmeters that can measure hydrogen sulfide at 30% concentration? Two options are provided: 1. For low flow rates, use a vortex flow meter imported from Japan to measure the flow rate under operating conditions ； 2. For high flow rates, use our thermal mass flow meters; their sensors are corrosion-resistant and can last 10–15 years, making them suitable for use with gases such as chlorine, phosgene, and hydrogen sulfide.
