  • Effectively Detect Hazardous Gas Leaks | Chemical Processing

    GuidelinesGas Detection OptionsThe Need For IntegrationAchieve Effective MonitoringAs shown in the selection decision tree (Figure 1), catalytic and infrared (IR) technologies can detect combustible gases. Of the two techniques, only the optical method lends itself well for point and area monitoring. Choose IR devices for detecting a single type of hydrocarbon or simple mixtures. Because they are unaffected by oxygen levels, such detectors are ideal for anaerobic processes, operations with high concentrations of corrosive agents, and areas with constant background of combustible gases. On the other hand, catalytic gas detectors are a better choice for monitoring hydrogen or hydrocarbon mixtures. Because catalytic detectors require oxygen gas concentrations in excess of 10% by volume to operate, they only suit situations where oxygen always is present. Moreover, catalytic gas detectors perform best in applications where the target gas normally is absent. For monitoring toxic gas leaks in congested spaces, electrochemical and solid-state gas detectors are the instru...
