Valero Energy Corp., the third-biggest U.S. refiner, yesterday said fourth-quarter profit more than tripled as the company benefited from its ability to process less-expensive sour crude oil. Valero Chief Executive William Greehey has said the company plans to add more capability to process sour crude.and was being considered the most likely buyer for some refineries that Citgo was trying to sell
So perhaps its selling some refineries, so it can get cash buy others that are a better fit for it
