Techno-economic assessment of a pulverized coal plant with CO2 capture, based on novels composite Pebax membranes

Tecno-economic analysis of a sub-critical pulverized coal plant, with carbon capture section, based on membrane separation. Effects of the introduction of three novel Pebax membranes are evaluated with Integrated Environmental Control Panel software, provided by Carnage University and NETL. After the introduction of global climate change problem, CO2 separation technologies are briefly described, focus on membrane separation. State of the art of membrane is described, highlights the pros. and cons. of each classes of material and provide a representation of the Robeson Plot. The third chapter explain all the inputs and hypothesis used for the simulations and result are showed in four chapter. Tecno-economic comparison between commercial Pebax and two novel composite Pebax is carried out. Two configuration of CO2 section are proposed: 2-step air sweep and 2-stage cascade. Characteristic parameters, as total membrane area, plant efficiency, energy consumption, capex, opex and cost of CO2 avoided are evaluated. In addition, sensitivity analysis is carried out to understand the effect of critical parameter on the system, to optimize the overall plant results.
