Ok, I did some air testing last year and the $hit has really hit the fan. Ill save the long story but Ive got data on some air emmisions. I need to take the concentration in PPM (volume) and get a mass emmissions rate in mass/time.
Its been a year since I looked at the spreadsheet I didnt the calculations on and I dont know what I did a year ago. The numbers look right but when I look at how I got them I cant figure it out. When I rerun the numbers with what Ive got now it comes out lower actually which theoretically is good, EXECPT when the Ohio EPA is auditing the project and needs me to justify how I did the calculations.
So heres an example of what I did:
Off gas stream:
MW: 94.4
ppm: 62.016
Flow rate: 310 cfm
the formula I used was:
Emission = concentration * flow rate * 1 lb-mole/386 ft^3 * Molecular weight * 1440 min/day
Can anyone else help me out here. Im completely freaking out here.
