1 Bitumen to Finished Products Presented by: Gerald W. Bruce Jacobs Canada Inc. Canadian Heavy Oil Association Technical Luncheon Calgary, Nov 9, 2005

2 Overview Why all the interest? Value chain Adding value to bitumen Finished products Refining challenges Typical US refinery configurations Complexity range Market for Oil Sands production Conclusions Fit the market

4 Light / Heavy Differential Source: CAPP High differentials make upgrading. Very attractive

5 Adding Value to Bitumen Production through refining 100% 90% 80% 70% 60% 50% 40% 27% 18% 12% Refining Secondary upgrading Primary upgrading 30% 20% 10% 42% Bitumen production 0% Production through Refining Source: Petro-Canada

6 Upstream vs Downstream Source: Petro-Canada

7 Global Decline of Light Sweet Crude Historical production vs. reserves Source: Valero Energy Company Observation: Crude is getting heavier, refineries were designed to run mostly light sweet crudes

8 Upgrading / Refining Incentives Capturing the Light/Heavy differential is real $$$ Example: refinery capacity = 100,000 bpd Heavy/light differential: $ 20 per barrel Assumption: bitumen blend = nominal 50% of the refinery feed Savings = 20 x 50% x 100,000 = $ 1,000,000 per day or $ 365 million/year Availability of low cost reliable feedstocks is attractive to US Refiners (with money to spend) Availability, pipeline infrastructure, price Bitumen is cheap for a reason Significant investment required in upgrading/refining required to be able to capture the margin

9 Upgrading? Synthetic Crude Oil (SCO) trades at a premium to WTI Current: $ 1US/bbl Bitumen Blends trade at a discount to WTI Current: $ 23 US/bbl Upgrading bitumen to SCO moves production up the value chain Example: production of 100,000 bpd of bitumen Assumption: SCO yield of 85% vol on bitumen SCO/bitumen differential: $ 23 per barrel Additional revenue: 23 x 85% x 100,000 $ 1,955,000 per day or $ 715 million/yr Upgrading to SCO is not for the faint of capital $ 40k per barrel of SCO product (upgrading only)

19 Processing Bitumen Blends The bitumen portion of the blend is nasty Bitumen characteristics: Heavy, tar like crude oil. Gravity and viscosity are high Challenging Chemistry Contains significant aromatic and asphaltene compounds. High in sulfur, nitrogen, and metals Also contains highly corrosive organic acids. Must be diluted or upgraded in order to ship.

20 Processing Bitumen Blends Not a good fit with refineries designed for light sweet crudes Need conversion capacity to handle bottoms Significant hydroprocessing of converted material Bitumen is H2 deficient Never seems to be enough H2 around Byproducts are plentiful and nasty Sulphur, Coke SCO works well in refineries designed for SCO

21 Processing SCO Level of upgrading Premium SCO vs Sour SCO Bottoms? Yes or no Fit with refinery Processing objectives Anode grade coking business? Opportunities to fit the SCO Asphaltene reduced SCO

22 SCO Challenges Quality Fit. % volume some ideal properties Jet Fuel smoke point >21 Diesel Cetane >45 Conventional Light/Heavy Crude Blend naphtha Synthetic Sweet Crude Today some questions on hydrocarbon mix poor quality distillates limit many refiners to 10% or less of crude diet Gas Oil to conversion units UOP > residue 11.3 high volume of low quality feedstock for cat cracking refineries Courtesy Alberta Chamber of Resources

23 Hydrogen Content Bitumen is hydrogen deficient SCO has is better The hydrogen to carbon ratio is a good indicator of how much work needs to be done on the molecules More hydrogen. Paraffins > Naphthenes > Aromatics For aromatics, the more rings, the lower the H/C ratio Heavier fractions have less hydrogen, with large multi-ring aromatics (like those found in bitumen). Lowest H/C

24 Hydrogen Content H/C ratio Gasoline Jet fuel Diesel Vacuum Gas Oil Residue Boiling Point (F) Crude: Brent Blend

25 Hydrogen Content The hydrogen content sets the refinery friendliness of a crude FCC units (the main gasoline producing machine in a refinery) are sensitive to the hydrogen content of the feed: Less hydrogen means heavier or more multi-ring aromatic feeds), gasoline yield decreases and coke yield increases. Getting hydrogen into the molecules is what really happens in upgrading and refining: Carbon rejection : coker units, followed by hydrotreating Hydrogen addition: hydrocracking units

26 Other Key Properties Sulphur: tight new environmental regulations sulphur at ppm levels on final products Nitrogen: causes NOx emissions and catalyst poisoning Metals: causes catalyst poisoning. New environmental concerns around mercury and selenium Conradson Carbon (CCR): coking tendency (yield losses) on conversion units High TAN: naphthenic acids may require special metallurgy on fractionation columns, furnace tubes, piping, etc.

35 Conclusions The time is right for significant oil sands development. Upgrading or not.. Depends on the market Security of supply will fuel the expansion of bitumen derived feedstocks in current and extended US markets. Refineries need to be reconfigured to make them bitumen friendly. Start to look much like an upgrader New markets provide the opportunity to tailor production to meet market needs.
