It could also prove prudent to not burn heavy oil and demand cleaner fuel. Not perfect, but it would certainly be better. It would have a serious impact on the economics of logistics but maybe that wouldn't be bad too.
Don’t you have to produce the heavier stuff when you produce the lighter stuff in a column? It’s my understanding that when you separate crude you end up with proportions you don’t have a lot of control over.
Most hydrocarbons are produced via cracking the molecules into the desired length. You can modify your refinery to get the right ratios that the market demands out of a barrel of crude.
