RECAP

In this project a study was made of the performance and cost of CO₂ capture integrated into four different generic refineries:

• Base Case 1) Simple refinery with a nominal capacity of 100 000 bbl/d
• Base Case 2) and 3) Medium and highly complex refineries with nominal capacity of 220 000 bbl/d
• Base case 4) Highly complex refinery with a nominal capacity of 350 000 bbl/d
• Main focus was on post combustion capture with a solvent (MEA).

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.
