In this proposed study, hydrogen and power generation by low-temperature geothermal energy supported Kalina cycle is thermodynamically investigated with an exergy efficiencies approaches. This combined plant includes a PEM electrolysis for generation. The key purpose of paper to generate in environmentally benign way. Furthermore, environmental impact analysis discussed investigate the carbon d...

In order to recover the energy loss due throttling in path of ammonia-lean solution Kalina Cycle System (KCS) 34, two redesigned cycles, which single-screw expanders that can perform two-phase expansion are used replace throttle valve, proposed this paper. The results show thermal efficiency and net work cycles higher than those original KCS 34. With concentration increase ammonia-water mixture...
