Abstract

Upon completion of the world largest post combustion CO2 capture plant – Petra Nova Project – MHIEng has demonstrated that commercial-scale CO2 capture plant is technically feasible. With the updated technology and lessons learned, the Advanced KM CDR Process has been developed, providing superior performance as usual but with a significantly lower capital cost. The cost reduction is contributed by the reduced size of the flue gas quencher and CO2 absorber, reduced design redundancy, and the modular design. The total project cost of the CO2 capture and compression is expected to be reduced by nearly 30% for the next large-scale plant. The Advanced KM CDR Process together with new solvent (KS-21) that targets at improving overall plant economics is as well under development. Also, KS-21 solvent is expected to have higher technical advantage comparing with existing KS-1TM solvent, such as higher stability and lower volatility. The preliminary pilot plant test showed that the KS-21 has 50% lower amine emission than KS-1TM while giving comparable energy performance. MHIEng will offer the Advanced KM CDR Process using KS-21 with attractive properties facilitating solvent management in early 2019.
