# I assume that you are referring to "Synthesis Gas", rather than "Synthetic 
gas." That being the case, I would disagree with you. :-) From what I can 
understand, the various "Synthesis Gas Processes" require high pressure, and 
as a consequence, the need to compress a large quantity of nitrogen dilutent 
makes the processes generally uneconomic. Your statement would thus be true, 
at teh present. However, if someone develops a synthesis gas process of some 
sort that only requires low pressure, then the presence of excess nitrogen 
from an air blown gas producer would not necessarily be an obstacle to using 
such gas for synthesis purposes.

# I would suggest that "Synthesis Gas" is "any gas mixture that will serve 
as feed to a process where another product is synthesised." "Synthesis Gas" 
should thus be defined by its chemical analysis, rather than the method of 
production. Note also that a gas mixture that is perfect for one process may 
be totally unsuitable for feeding to another process.
