OK, but from what I have read of other ULSD processes, they often add hydrogen.....but maybe what JBII does is a bit different, due to the coke "sacrifice".....
....whether the refinery can revamp an existing hydrotreater or must build a new one; and the cost for catalyst, hydrogen, and other requirements to produce the ULSD.
ULSD production requires added hydrogen usage in the distillate hydrotreater, thereby increasing hydrogen consumption per unit of distillate feed
