| Abstract: | The design and actual operation value of the yield of synthetic crude oil products in an oil sands bitumen upgrader is analyzed. The optimization scheme of upgrading process to improve the yields of synthetic crude oil products is discussed in combination with the existing units. The results show that the process combination of solvent deasphalting followed by thermal cracking and the inadequate understanding of the viscosity of the deoiled bitumen result in the low actual operation yields of the synthetic crude oil. The process of vacuum residue thermal cracking first and then solvent deasphalting is discussed. Compared with the original design, the yields of products is 7.5 percentage points higher than the actual operation value, 3.0 percentage points higher than design value. |
