Converting 25MMscfd of Natural Gas to kg/hr: A Comprehensive Guide

[Yr11Kid]

Hi everyone

i need help converting 25MMscfd of natural gas to kg/hr
i calculated the molecular weight of the natural gas to be 18.94g/mol
the feed conditions are 6900kPa and 298K

i'm pretty sure 1MMscfd = 1180m^3/hr at standard conditions, I'm not sure how to work this out for the feed conditions

You can directly compute your mass flow in kg/hr as follows:

mass flow = standard density X standard volumetric flow rate.

Your standard volumetric flow rate is given as 25 MMscfd

You can figure the standard density from your molecular weight:

standard density = [ MW (natural gas) / MW (air) ] X standard density of air.
