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
