1000 TPD CO 2 CAPTURE PLANT FEED STUDYDEVON JACKFISH 1 OILSANDS OPERATIONSFEED STUDY REPORTDEV-JA-03-001-1 (R1)7 Conclusions The study work has shown the technical feasibility of fabricating and installing a modular 1000tonne per day (tpd) CO 2 capture plant. The indicated project execution schedule of 20 months from contract award through start-upreflects the expected advantages of HTC’s approach of employing a standardized design with amodular shop-fabricated plant. The 1000 tpd sizing is a very good fit for “typical” SAGD developments such as Devon’s Jackfish 1that deploy 250 MMBtu/hr OTSG’s, in that a 1000 tpd unit can capture the exhaust off threeboilers. The CO2 capture process configuration is of one absorber and one stripper type. Absorberdiameter is 7.62 m and stripper diameter is 3.35 m. Total CO2 Capture plant foot print for thismodular design is estimated to be 8000 m2 (80m X 100m). The 1000 tpd modular approach will allow operators to phase-in CO 2 capture in SAGDoperations in 3-boiler increments rather than considering capture from an entire facility at once. The estimated CAPEX for the project spread simply over 20 years of production at design rategives an indicated CAPEX component of capture cost of about $11.98/tonne. Using a weighted average cost of capital of 8%, assuming a long-term average plant throughputof 85% of design rate, and assuming a plant availability of 95%, the CAPEX component of CO 2capture cost from SAGD facilities will be under $37/tonne. HTC estimates the operating cost of a CO 2 capture unit to be approximately $30/tonne includingfuel costs at $5/GJ ($13/tonne). The indicated total CO 2 capture cost at 8% cost of capital is under $70/tonne. It is probable that the fuel cost can be significantly reduced through project specific heatintegration efforts and optimization of the inlet cooling system. It is recognized that the cost of emissions reduction must include, in addition to the cost ofcapture, consideration of additional emissions from capture operations as well as compression,transportation and drilling and injection costs. However, as the Alberta Carbon Capture andStorage Development Council report states, it is generally regarded that the cost of capture is 70to 90% of the cost of emissions reduction.The study results indicate that the previously published view of the expected cost of CO 2 emissionreduction from SAGD operations to be from $175 to $230 per tonne is significantly overstated.HTC PURENERGYPage19 (19)
