 · The coal supply to the PC plant is linearly related to the power-plant gross thermal output. Because the gross thermal output for the power plant with sorbent‐based CO 2 capture is estimated at nominally 11% less than that for the Econamine process, less coal is burned and thus less Hg, SO 2, SO 3, NOx, etc. are created.
