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.
The 10th Trondheim CCS Conference is an internationally leading CCS conference. It was held June 17-19 in Trondheim, Norway. At the Conference, international researchers, policy makers, industry and academia gathered to present and discuss the latest CCS research.
