Hmmmm .. we can build export plants... essentially a pipe a ship backs up to and the valve is opened .... but we can’t refine our own oil ?
Why do you think we cannot?
But on the other hand, if we can import and refine cheaper heavy oil at $85/barrel and export our lighter oil at $100/barrel, why would we not?
We already spent the billions of dollars upgrading many refineries to process the heavy cheaper stuff.
By the way, it is a bit more complicated to liquefy natural gas. That is why the plant cost $10 billion.
