With the utilisation of binary mixture as working fluid in a power generation cycle, higher heat conversion rate will be achieved in the boiler which results in more efficiency. In this paper two kalina cycle designs using binary mixtures as working fluid were compared, the cycle efficiency as a function of turbine inlet and separator outlet were calculated for the kalina cycles. The cycles property values at each points are obtained from matlab. The optimized design were identified at various turbine inlet conditions resulting in energy conservation.
