Morning Twitter Messages -- May 18

I wish I didn't have to leave for an assignment. Some of these would make excellent blog posts. Maybe some reader will take them and run with them. 

 Petcoke in the tar sands is turning American refineries into coal factories.
  • There is 24 percent more CO2 embedded in a barrel of tar sands bitumen than in a barrel of light oil.
  • 15 to 30 percent of a barrel of tar sands bitumen can end up as petcoke, depending on the upgrading and refining process used.
  • Of 134 operating U.S. refineries in 2012, 59 are equipped to produce petcoke.
  • U.S. refineries produced over 61.5 million tons of petcoke in 2011 – enough to fuel 50 average U.S. coal plants each year.
  • In 2011, over 60 percent of U.S petcoke production was exported.

Here is a whole string of interesting medically related content. The oral hygiene part is notable.

And finally, this last one is one satisfying piece of work. Go read the letter at the link
