Infrared Technology for Hydrocarbon Gas Detection

variety of combustible gases the sensor can detect. Fig. 1 Catalytic Bead Sensor . Although catalytic bead sensors have been in use for decades, the technology has some drawbacks. One critical limitation is the inability to operate in an environment deficient in oxygen since the bead requires efficient oxidation of hydrocarbon gas; oxygen levels impact oxidation efficiency; and hence, the ...

Oilfield Dynamometer Surveys: Pump Card Interpretation ...

Usually the well is put on tag due to pumping problems related to gas interference but a much better way to resolve the situation is to design the gas interference out (either in the downhole gas separator or handle the gas in the pump's design). Tagging is not only destructive to the pump, rods and tubing, but tagging also reduces the downhole Plunger Travel. A 2" tag is 2-inches of lost ...

Gas Sensor - an overview | ScienceDirect Topics

Gas sensors are used for detecting a wide range of gaseous substances in the atmosphere, including pollutants, toxins and combustible gases. In the case of combustible gases, the sensing element is a platinum wire coated with a mixture of substances which catalyse the oxidation of the gases. The coil is heated by passing a current through it; this causes combustion to occur, generating additional heat …
