<DIV><FONT face=Arial size=2><STRONG>You ask an interesting
question:</STRONG></FONT><FONT face=Arial size=2></DIV>
<DIV>
<DIV> </DIV>
<DIV>I have a question regarding combustion quality of PG. </DIV>
<DIV>When we talk about natural gas, in short 'Methane index/Methane Number'
provide combustion quality. For gasolin/petrol it is 'octane rating'. Can we use
'Methane number' as indicator for PG also ??</DIV>
<DIV> </DIV>
<DIV><STRONG>According to this Paper </STRONG></FONT><FONT

the answer is a qualified yes, but when you look at the gas analysis of the
mixed gases used for the tests, they seem a little out of step and too clinical
for practical application. The realities of PG is that it's quality and gas
analysis covers a wide spectrum, therefore creating extreme variations of the
knock point of the combustion cycle, and this was the conclusions of this
Paper.</STRONG></FONT></DIV>
