【Abstract】 To enhance energy utilization rate while treating medical waste in a clean way, a system coupling solid waste plasma gasification with modular nuclear reactor for co-production of electricity and hydrogen was proposed. In this novel coupling system, medical waste treated by plasma gasification treatment to generate high-temperature syngas. The syngas was then cooled using steam and feedwater from the SMR(small modular reactor) power plant. After cooling, the syngas was purified and fed into a water-gas shift reactor. The product gas was then purified by a pressure swing adsorption(PSA) unit to produce hydrogen. The performance of this new system was evaluated from a thermodynamic perspective using a specific modular nuclear reactor as a case. Results show that the medical waste to energy efficiency is 58.83%, the total efficiency and the exergy efficiency of the integrated system reach 54.24% and 54.23%, respectively. Additionally, the net present value of the novel coupling system is approximately 777 535 300 yuan, with a dynamic payback period of 3.71 years. The novel coupling system is both efficient and economically feasible.更多还原
