A laser diode sensor for In-Situ monitoring of H2S in the Desulfurizing Device

摘要：

Hydrogen Sulfide is a highly toxic and corrosive gas which is generated in many industrial processes. Gas detectors based on Tunable Diode Laser Absorption Spectroscopy (TDLAS) have been used in a wide variety of applications for safety and environmental field. In order to meet the requests of industrial field anti-explosion, a laser diode sensor for H:S in-situ monitoring has been developed, combining with wavelength modulation spectroscopy technology, White cell technology and current loop technology. The important features of the H,S sensor are the speed of response, non-intrusive in-situ safety measurement, zero cross interference from background gases and long distance transmitting with the detection limit of 10ppm.m. The continuously monitoring results demonstrate that the sensor is suitable for application of H2S monitoring in desulfurizing device.
