| 1 Interactivity
between the products requires license of C6HCDPmatch and one of the other
products. |
| 2. calculations above can be performed at natural gas pipeline
operating conditions, metering conditions, compressor inlet conditions, gas
turbine inlet conditions, and separator vapor outlet conditions |
| 3. very rich natural gas is defined here as > 1% C6+ |
| 4. extends Gas Analysis mathematically to match calculated dp
with measured dp temp at pipeline pressure |
