my points are :
a. The quality / composition of gas cannot be changed by a cng station. All a cng station can do is to compress it upto required standard, less than standard or higher than standard.
b. Remove the impurities coming with the gas through main gas pipelne or do not remove them.
c. Store enough gas before dispensers, so that users get cooler gas or have lesser storage thus higher temperature gas.
Regarding my first post in 1917 days.. yeah you are absolutely correct in this respect. Reason is I had forgotten about this website and my registration. I just found it again by chance.
Anyway, I start liking this forum. Its a decent and tolerant place to discuss different point of views. We all can have varied points of view. But these are discussed in neat and patient manner, and much better than some other places having lots of intolerant and impatient people.
Good work is being done here by all the senior contributors.
