Hi,

a) You need to know the composition of your steam to calculate the molecular weight of the gas >>> M w  (g/mol)

B) Nm3/h means volumetric flow rate at (0 C and 1 bar ) i.e 1 mole =22.4 liter   >>> Moles/hours 

 

>>>> Mole/h * MW= gr/h /1e06 = MTPH (metric ton per hour) 

 

Hope this is helping you

Dear Sir,

 

I know conversion from Kmol to kg for feed flow. and also molecular weight contribution to this . But i wanted to know how NTP conditions will affect final calculation here.

 

Best Regards,

Chetan Chavan

Hi,

Thanks to explain better what is your requirement? 

Normal means specific condition (0 C and 1 atm) , if you change the condition the consequence will be a change in molar volume (perfect law gas  V =R*T/P)  .

Note : You may use this calculator to support your work

Good luck
