SO2 to SO3 conversion calculations
« on: 22/07/2012 01:34:28 »
Hi…..
The conversion of SO2 to SO3 in Catalytic converter is based on equation below:
SO2  +  ˝ O2 -------> SO3
I got problem in finding SO3 moles in, kindly help me…
Details are following;
Temperature: 688 K
Pressure : 1 atm
Total Number of Moles : 408 Kmoles
Moles of SO2 : 46.97  Kmoles
Moles of O2: 38.39   Kmoles
Kp =  397
(value calculated from Bodenstein equation
Log Kp = 5186.5/T + 0.611 * log T – 6.75 
Temperature is in K. The above calculated value was verified from book “Process industries by Norris Shrieve, page 333”

Kindly tell me in detail , how to calculate SO3 moles…..

Regards,
