Abstrakt

The study aimed to analyse detection methods of ammonia leakage by various electrical methods. Rapid detection of the escape of hazardous technical gases is extremely important in large chemical plants. The basis of the research was the use of a specialized camera, model FLIR GF306, to detect a leak of selected gases in a narrow infrared band. In laboratory conditions, the controlled emission of gaseous ammonia at various concentrations was simulated, and gas detection was performed: a) using a narrow infrared thermography method, and b) by a portable electrochemical detector dedicated to detecting ammonia. The turbulent flow of gas into the environment and high thermal contrast between the expanding gas and the background are the conditions for effective gas detection with a thermal imaging camera operating in a narrow infrared band.
