ReCap: Understanding the Cost of Retrofitting CO2 capture in an Integrated Oil Refinery

Refineries are characterized by the large number of stacks with flue gases of varying CO2 concentration and sulphur content. The stacks are distributed over the refinery area and if CO2 is to be captured from several stacks, several absorbers are needed and in some cases also a flue gas desulfurization (FGD) unit upstream of the absorber. The rich solvent from the absorbers is ducted to one single stripper. Altogether 16 post-combustion CO2 capture cases were investigated for the generic refineries: 3 cases for Base Case 1, four cases for Base Case 2, 3 cases for base case 3 and six cases for Base case 4. Each capture case includes capture from between one and five stacks.
