Heat values of gas components

Heat values of gas components

Heat values of gas components

(OP)
Hello all:
Looking for help to find a table of heat values for natural gas components that covers decanes ++
Thanks
Geoff

RE: Heat values of gas components

I had no luck finding anything over C10 paraffins in my reference material.  However, I did plot the various paraffin's heating values against their C/H ratios and got an excellent correlation.

Depending on the accuracy you need, this might be an option though extrapolating data always makes me somewhat nervous.  However, the heat release from burning hydrocarbons directly related to the C and H content so this should be a valid approach.

RE: Heat values of gas components

Heats of combustion gas-gas in Btu/lb for the principal hydrocarbons, rounded and averaged from different sources:

C1            21,510
C2            20,420
C3            19,940
n-C4         19,600
n-C5         19,510
n-C6         19,400
n-C7         19,320
n-C8         19,260
n-C9         19,220
n-C10       19,180
H2S           6,150
H2            51,620
CO            4,350


RE: Heat values of gas components

The following Net Heats of Combustion (to form H2O gas and CO2 gas) in Btu per pound at 60 degrees F are from page 2 of "Data Book On Hydrocarbons" written by J.B. Maxwell and published by the D. Van Nostrand Company in 1950:

C1      21,500
C2      20,420
C3      19,930
nC4    19,670
nC5    19,500
nC6    19,240
nC7    19,160
nC8    19,100
nC9    19,050
nC10  19,020
nC11  19,000
nC12  18,980
