Question

How do you convert 664.71 MSCFH (million standard cubic feet per hour) of natural gas to MBtu/hr? I am looking for the firing rate of a burner. I know you have to use enthalpy tables for temperatures or something of the composition. (the composition is mainly CH4 Methane)

Answer 1

We know that,

1 million standard Cubic feet per day of natural gas flow= 41,571.45 cubic feet/hour in flow rate

1 million standard cubic feet per 24 hour of natural gas flow= 41,571.45 cubic feet/hr

1 million standard cubic feet per hour of natural gas flow= cubic feet/hr

=1732.14 cubic feet/hr

Also we know that, 1 cubic feet=1000 Btu

also 10⁶ Btu=1 MBtu

1 Btu=10^-6 MBtu

therefore we can say that

1732.14 cubic feet/hr= 1732.141000 Btu/hr= 1732.14100010^-6 MBtu/hr

= 1.732 MBtu/hr

Which can be written as

1 million standard cubic feet per hour=1732.14 cubic feet/hr= 1.732 MBtu/hr

Now it is given that, there is 664.71 MSCFH (Million standard cubic feet per hour)

So it will be equal to =664.711.732 MBtu/hr= 1151.28 MBtu/hr
