ABSTRACT
The trend of processing more heavy and sour crudes, the shift in demand away from gasoline toward more distillate, and more stringent fuel qualities change the fuel and hydrogen balances in most refineries (Speight and Ozum, 2002; Ancheyta et al., 2005; Hsu and Robinson, 2006; Gary et al., 2007; Liu et al., 2009; Speight, 2011a). Finding the right solution to managing fuel gas and hydrogen requirements has become essential for refineries to remain profitable. The refinery gas value is higher for hydrogen generation than for generating power and slightly lower than the value for using it as chemical feedstock.
