Abstract
|
|
|
Objectives: The emission characteristics of aldehydes were investigated in five industries for the efficient management of aldehydes.
Methods: Aldehydes and THC were measured from the stack and boundary of facilities. The relative concentrations and odor contribution of aldehydes were evaluated.
Results: The concentrations of aldehydes in the asphalt manufacturing and printing industries were relatively high. Formaldehyde met emission limits for all facilities. According to the odor contribution analysis of aldehydes, i-valeraldehyde and butyraldehyde, which have a relatively low odor threshold value, were found to be the major odor-causing substances in the painting and textile processing industries.
Conclusions: Among the aldehydes, the major emission compounds were formaldehyde in asphalt manufacturing, acetaldehyde in the paper manufacturing and textile processing industries, and butyraldehyde in the printing and painting industries. Therefore, to increase the effectiveness of aldehyde reduction, proper control devices need to be installed and operated according to the emission characteristics of aldehydes.
