Question
A process equipment emits 5 kg/h of volatile organic compounds (VOCs). If a hood placed over the process equipment captures 95% of the VOCs, then the fugitive emission in kg/h is
Correct answer
(A) 0.25
Solution
Total VOC emission = 5 kg/h.
Capture efficiency of the hood = 95%.
Captured VOCs = kg/h.
Fugitive emission = Total emission Captured VOCs = kg/h.
Capture efficiency of the hood = 95%.
Captured VOCs = kg/h.
Fugitive emission = Total emission Captured VOCs = kg/h.
