Does anyone have a more complete list than the one in D3588-91? I am looking for net and gross values for 1,3 butadiene and can not find them anywhere.

Pseudotexan,
I found the following values in a calculation sheet which I know is currently in use, but I do not know the original source of the data
1-3 Butadiene Gross/cubic foot 2879.9 BTU
Nett/cubic foot 2729.0 BTU
Hope this helps

Those were the values I was able to come up with from a different source. Thank You. I am still looking for a more comprehensive list like Table-1 in D-3588. It is very limited but I frequently need the gross and net values along with the summation factor and have to scramble to find them.

What was your source. I have since found the following excel spreadsheet at
http://www.geocities.com/irbyhl/Hydrocmw.xls . They reference the GPSA for their data

I got it from one of the gas manufacturer sites along with the compressability value I was looking for. Then I corroborated it with our new applications engineer who had needed the value before. The spreadsheet you referenced is a great source of information thanks!
