Design and implementation of a portable infra-red sensor for hydrogen sulfide (H2S)

This document shows the development of a portable infrared sensor for the detection of sulfur components. The sulfur component usually are found in gas effluents of the tire pyrolysis process. This method is typically used like a mecanism for recycling tires, that is a huge environmental problem generated by the automotive growth. The pyrolysis process also generates greenhouse gases that cause phenomena such as acid rain [I] by the presence of sulfur compounds such as hydrogen sulfide (H₂S). So this is the target gas that in this proyect is going to be detected. This proyect has a implementation phase of the optical detection technology and test exposures of the sensor to the target gas. The sensor that was developed is a portable infra-red sensor for the detecction of the H₂S, and satisfactory results were found at the detecction of the target gas.
