I suspect your right! The conversions now should be allot better. I still think CNG will be the future but at my age I may not get to see it.
Of course you know this a lot of the Shale Plays don’t have any propane in the gas. Haynesville gas typically runs about .990 on BTU’s if it was not for the high CO2’s and H2S the gas could go unprocessed except for removing the water. I know that our Waskom plant sold all the propane it could this winter because of high demand.
