A systematic method is proposed for the selection of working fluid mixtures in a solar Organic Rankine Cycle (ORC) system in view of operating variability. The method is based on a sensitivity analysis procedure where several operating and design par

We propose a systematic approach for the preliminary screening of binary amine mixtures as CO2 capture candidates considering several important properties as selection criteria. The proposed approach consists of several decision making stages, which

A generalized framework is proposed for the optimal design of post-combustion CO2 capture processes based on a systemic and flexible equilibrium separation model that employs orthogonal collocation on finite elements (OCFE) techniques. Within this co
