摘要：
Renewable energy synthetic ammonia technology not only helps solve the problem of high energy consumption and high emissions in the traditional synthetic ammonia industry, but also provides a new way for the storage and consumption of renewable energy. In this work, an optimal design model of renewable energy synthetic ammonia system was established to address the seasonal demand of ammonia. The optimal configuration and operation scheme were determined, and the influences of seasonal ammonia demand on the design and operation characteristics of the system were analyzed. The results show that, compared with the case where ammonia is used as energy storage medium, the scale of the required synthetic ammonia production system powered by renewable energy increases significantly, and the cost of ammonia increases by 21% when ammonia is used as the raw material of nitrogen fertilizers. The loads of chemical production units and storage units present distinct performances of off-season and peak-season with the seasonal shift of the ammonia demands. Besides, in both of the above-mentioned two cases, the operation of the battery energy storage unit will be mainly determined by the downstream chemical production units, and the role of the energy storage battery unit is to smoothen the fluctuation of renewable energy so as to ensure the continuous and stable operation with low-load of chemical production units when the deficit of renewable energy is presented. © 2021, Editorial Board of CIESC Journal.
