THEME: Drivers behind the Success of Processing Opportunity Crudes FOCUS: The 3rd biennial Opportunity Crudes Conference will concentrate on five driving forces that can enhance profitability and sustain business goals in processing heavy sour crudes, oilsand/bitumen, extra heavy oils, and high TAN crudes from around the world: •
Increasing distillate yield and quality
•
Converting high sulfur fuel oil into valuable products
•
Boosting propylene output
•
Mitigating fouling and corrosion
•
Minimizing carbon footprint to meet LCFS and low-carbon intensity rules
