Monitoring and Analyzing VOCs Pollution Emissions in Airport with SOF-FTIR

Abstract

Abstract: To study the impact of emissions at an airport on local air quality, a measurement campaign at the Beijing Capital International Airport was performed from 10 December 2014 to 16 December 2014. Measurements of, CO,C2H4 and C6H14 were conducted with solar occulation flux -fourier transform infrared spectrometer (SOF-FTIR) system to determine real in-use emission indices of aircraft . The characteristic concentration values of three target gas were analyzed .The results shows that there was a high correlation between them and the average column concentration of ethylene, hexane and Carbon monoxide in the airport are 13.18ppmm 97.82ppmm , 3065.56ppmm, separately. By combining the measurement data released by ICAO, it can be concluded that the emissions of ethylene and hexane at an international airport have reached the levels of total hydrocarbon emissions 3.32% and 66.96%, respectively. The results show that the SOF-FTIR technology has good consistency with ICAO data and provides technical support for the assessment of aircraft emissions.
