The theoretical study proposed here is based on the energy recovery of sensible heat sources of medium and low temperature levels from Rankine power cycles in which binary mixtures of carbon dioxide and organic fluids are the working fluids. In this sense, the impact of these blends on performance parameters in the basic Rankine cycle configuration is addressed, as well as, optimization analyses of global conductance to ensure the highest production of net power cycle. The results allowed identifying what mixtures stand out in each performance indicator, particularly at net power and first law efficiency.
