Fugitive emission rate calculations

[koshyeng]

Please suggest me some references or articles to calculate fugitive emission rates.

For example fugitive emission rates from pump packing emissions,valve packing emissions, flange emissions etc.

Addition to my question above,

If my emissions from pump packing is 12000 ppm(v) then how should I estimate emission rate in lb/hr for this specific emission?

Thank You.

PS: Apologies for posting twice as I didnt hear any response from other forum.
