The Electric Power Research Institute (EPRI) undertook a multiyear effort to understand the landscape of postcombustion CO₂ capture technologies globally. In this paper we discuss several central issues facing CO₂ capture involving scale, energy, and overall status of development. We argue that the scale of CO₂ emissions is sufficiently large to place(More)
A hybrid system combining amine scrubbing with membrane technology for carbon capture from natural gas combined cycle (NGCC) power plants is proposed in this paper. In this process, the CO2 in the flue gas can be enriched from 4% to 18% by the membrane, and the amine scrubbing system will have lower capture costs. Aqueous piperazine (PZ) is chosen as the(More)
