I’m learning something new here.
I live in CO and we have dozens of different blends and grades in the state depending on altitude etc.
Are you guys saying that, theoretically, all these different gasoline blends could come from one tank farm, and use one basic gasoline ingredient?
The difference in Vapor Pressure for gasoline is often modified by the inclusion or exclusion of amounts of butane.
Different areas of the state likely have their own tank farms where the local recipe is blended. That is common elsewhere, but I have not designed/built gasoline/diesel tank farms & loading terminals in the Rocky Mountains where altitude changes rapidly with distance. I have in more flat land and that is common. What I have seen is the only different in most locations is the brand name additive.
However, I did that work when we mostly used MTBE and not so much since the ethanol push. I expect but do not know, that the ethanol is already blended into the large gasoline tank(s). To blend the ethanol per truck would require additional tanks(s) and pumps per facility from the previous designs.
That’s correct. I used to live in Vicksburg, MS. On Saturdays there were up to 20 tankers with different logos parked on the shoulder waiting their turn to load at the local facility. I’ve made it a point to talk to tanker drivers delivering to stations for years to find out where they’re loading. Gasoline is gasoline. The only difference between brands is the additive package.
