As I mentioned it is better to seperate the two terms light-heavy and sweet-sour
it can be light-sour and sweet-heavy
high sulfur crude is a nightmare to transport and refine. screws up the FCC's. cause equipment damage form corrosion etc etc
heavy : more diesel
light: more gasoline/petrol
So, Urals is sweeter than Arab/ Iran Light, with lesser Sulfur content and is better for equipment and process, right?
Since we have settled sweetness/ sourness issue, how much heavier Urals is compared to both Arab and Iran Light?
