The reduction of CO2 emissions is a very challenging issue. The capture of CO2 from combustion processes is associated with high energy consumption and decreases the efficiency of power-producing facilities. This can affect the economy and in specific cases, such as waste-to-energy plants, also their classification according to legislation. To allow the minimization of the energy consumption, a model of a membrane-based post-combustion capture was developed. The optimized parameters are the pressures and membrane properties of individual membrane stages. Model stands on the principle of a network flow problem, where all non-linear dependencies are linearized and replaced by a black box to ensure the optimality of results. The functionality of the model was verified on a case study and the results of the optimization are presented in the paper and implications of the energy consumption for a waste-to-energy plant are discussed.
