| Popis: | CO 2 emissions from bitumen upgrading represent a major source of greenhouse gas emission in the oil sands industry of Canada. In this paper, optimal design of bitumen upgrading plant was studied with the aim of CO 2 reduction. Various CO 2 capture techniques including oxyfuel combustion, pre–combustion and post–combustion are modeled and incorporated into an integrated optimization model for simultaneous design of bitumen upgrading plant and the associated utility plant. To solve the resulting large-scale mixed integer nonlinear programming (MINLP) problem, augmented Lagrangian decomposition method is used. Optimal configurations under different scenarios (including plant capacity, natural gas, electricity and crude oil prices, and carbon tax) are discussed. The key findings of this study include: (i) hydrocracking for bitumen upgrading is favored, (ii) producing extra power and high–quality duty with a gas turbine burning natural gas is beneficial, and (iii) carbon capture with pre–combustion technology is suggested. |
