A coal-fired power plant with an scrubber has an overall removal efficiency of 85%. But rather than treat the entire stream to 85% removal, it has beenproposed to treat part of the flue gas to 95% removal, and tobypass the remainder of the gas. If the reblended stream muststill satisfy the overall removal requirement of 85%, what fraction of the flue gas stream can be bypassed around the scrubber?
