Here is a starting place on the current use of bottoms. An email I posted on the yahoo thread a few weeks ago.

Eric,

There are a number of options for handling of the refinery bottoms. The bottom portion of the crude oil barrel is referred to as vacuum tower bottoms (VTB) or resid. This material can be blended off to heavy fuel oil for power plants or ships. A second alternative for the resid would be the production of asphalt. A third alternative would be the production of petroleum coke in a delayed coking process. A fourth alternative is mixing the resid with other streams and feeding the mixture to a fluid catalytic cracking unit for the production of gasoline and diesel fuel. The degree to which each refinery does any of these things depends upon the available processing equipment and the quality of crude oil that is processed. I have more information. Let me know what you need.

Dennis

IMO, these current uses / revenues are going to pretty much pale in comparison to the revenues that will be realized through the production of high quality diesel.
