  •  What about ethanol pipelines? (4+ / 0-)

    In metro areas they use pipelines to move gasoline thus saving lots of money. I have heard that ethanol is not transportable via pipeline. I do not know why although I heard it may have something to do with electrostatic buildup. does anyone know this?

    •  Interesting... (8+ / 0-)

      I don't know why there'd be a problem with electrostatic build-up... ethanol is not polar, as water is, and doesn't shed electrons very easily in pure form... I would think it would be better in that regard than water is.


      Ah.  The problems with pipelines appear to be:

      • Ethanol icks up water very easily (and the last thing you want is water in your gasoline mix).  This would mostly be a problem with pipelines that sometimes carried gasoline and other times carried ethanol, or carried only ethanol, but at intervals.
      • Logistical problems with existing pipelines (which don't go where the ethanol is.)
      • Expense of building new pipelines when, at the moment, there is a fairly low volume of ethanol to transport.

      Here's a paper on it.

      If I remember correctly, pipelining ethanol could be done, but not through the existing pipes -- something about a different lining material being necessary.  So it's back to a scaling issue -- if there's enough being shipped, it may become worthwhile to build new pipes.  (And/or retrofit the old ones.)
