Cement Plants - Membrane Technology and Research

MTR's capture process for cement plants has the same general form as our process for coal fired power plants. However, because the flue gas has a higher CO 2 concentration, the energy consumption per tonne of CO 2 captured is reduced and the cement capture plant only requires half of the membrane area. Because membranes do not require steam to drive the separation, there is no need to add a ...
