|Crudes are classified and priced by density and sulfur content Crude density is commonly measured by API gravity •API gravity provides a relative measure of crude oil density •The higher the API number, the lighter the crude Light crudes are easier to process Heavy crudes are more difficult to process Crude sulfur content is measured as a percentage •Less than 0.7% sulfur content = sweet •Greater than 0.7% sulfur content = sour •High sulfur crudes require additional processing to meet regulatory specs Acid content is measured by Total Acid Number (TAN) •Acidic crudes highly corrosive to refinery equipment •High acid crudes are those with TAN greater than 0.7
|Source: Industry reports NOTE: Red line represents the average crude quality by decade (actual and projected) Majority of global reserves are light/medium sour Most quoted benchmark prices are light sweet crudes •WTI (West Texas Intermediate), Western Hemisphere •Brent (North Sea Crude), Europe Historical trend shows global crude supply becoming heavier and more sour

|Need conversion capacity to capitalize on sour crude discounts •Hydroskim — Breakeven or moderate margins; High resid yield When margins are positive — increase crude runs When margins are negative — decrease crude runs •Cracking — Better margins; Lower resid yield •Coking — Best margins; Lowest resid yield Maximize heavy crudes

|Depending on refinery configuration, CARBDepending on refinery configuration, CARB gasoline pool could be reduced by 2% to 4%gasoline pool could be reduced by 2% to 4% net of ethanol net of ethanol Model changes drive increase in ethanol content from 5.7% to 10% by volume Sulfur content must be reduced to accommodate NOx increases from ethanol Sulfur reductions require additional hydrotreating of FCC gasoline Aromatics change reduces reformate blending and FCC gasoline cut points, which increases need for alkylate and raffinate
|Definition •Separating crude oil into different hydrocarbon groups •The most common means is through distillation Process •Desalting — Prior to distillation, crude oil is often desalted to remove corrosive salts as well as metals and other suspended solids. •Atmospheric Distillation — Used to separate the desalted crude into specific hydrocarbon groups (straight run gasoline, naphtha, light gas oil, etc.) or fractions. •Vacuum Distillation — Heavy crude residue (“bottoms”) from the atmospheric column is further separated using a lower-pressure distillation process. Means to lower the boiling points of the fractions and permit separation at lower temperatures, without decomposition and excessive coke formation.
|Definition •“Cracking” or breaking down large, heavy hydrocarbon molecules into smaller hydrocarbon molecules thru application of heat (thermal) or through the use of catalysts Process •Coking — Thermal non-catalytic cracking process that converts low value oils to higher value gasoline, gas oils and marketable coke. Residual fuel oil from vacuum distillation column is typical feedstock. •Visbreaking — Thermal non-catalytic process used to convert large hydrocarbon molecules in heavy feedstocks to lighter products such as fuel gas, gasoline, naphtha and gas oil. Produces sufficient middle distillates to reduce the viscosity of the heavy feed. •Catalytic Cracking — A central process in refining where heavy gas oil range feeds are subjected to heat in the presence of catalyst and large molecules crack into smaller molecules in the gasoline and surrounding ranges. •Catalytic Hydrocracking — Like cracking, used to produce blending stocks for gasoline and other fuels from heavy feedstocks. Introduction of hydrogen in addition to a catalyst allows the cracking reaction to proceed at lower temperatures than in catalytic cracking, although pressures are much higher.
|Definition •Linking two or more hydrocarbon molecules together to form a large molecule (e.g. converting gases to liquids) or rearranging to improve the quality of the molecule Process •Alkylation — Important process to upgrade light olefins to high-value gasoline components. Used to combine small molecules into large molecules to produce a higher octane product for blending with gasoline. •Catalytic Reforming — The process whereby naphthas are changed chemically to increase their octane numbers. Octane numbers are measures of whether a gasoline will knock in an engine. The higher the octane number, the more resistance to pre or self-ignition. •Polymerization — Process that combines smaller molecules to produce high octane blending stock. •Isomerization — Process used to produce compounds with high octane for blending into the gasoline pool. Also used to produce isobutene, an important feedstock for alkylation.
|Definition •Processing of petroleum products to remove some of the sulfur, nitrogen, heavy metals, and other impurities Process •Catalytic Hydrotreating, Hydroprocessing, sulfur/metals removal — Used to remove impurities (e.g. sulfur, nitrogen, oxygen and halides) from petroleum fractions. Hydrotreating further “upgrades” heavy feeds by converting olefins and diolefins to parafins, which reduces gum formation in fuels. Hydroprocessing also cracks heavier products to lighter, more saleable products.
