Step 1 :
we have mol fraction, next step is to calculate individual moles by multiplying individual mol % by total no. of moles in stream.
Moles of A = mol fraction of A * Total Moles of stream
calculate moles for each component in the stream.
Step -2 :
now we have moles of each component in the stream next step is to calculate weight of each component by multiplying individual moles by molecular weight
weight of A = moles of A * molecular weight of A
calculate weight for each component in the stream.
Step 3 :
now we have weight of each component in the stream, next step to calculate weight % of each component by follwoing
Wt% of A : weight of A / total Weight of stream.
Step – 4
by using following formula we can calculate ppm from wt%
ppm = wt% * 10^4
if we have wt% fraction then,
ppm = wt fraction * 10^6
