Steam power plants release more than half of the primary energy input as ultra low temperature heat below 40^∘C into the environment causing thermal pollution. The emitted heat has a very low exergy content making it challenging to use as heat input by another process. Adsorption desalination combined with reverse electrodialysis can be powered by this heat and convert it into electricity. Thus, the system can mitigate thermal pollution and generate electricity at the same time. This study combines a validated reverse electrodialysis model with a dynamic adsorption desalination model that is validated with experimental data within this work. The experiments were conducted using a small‐scale adsorption desalinator and silica gel proving the feasibility of the regeneration at heat source temperatures as low as 40^∘C. The simulations of the integrated system analyse different heat integration scenarios showing exergy efficiencies up to 15% and energy efficiencies up to 0.55%. Hence, the system could generate 65 kW electricity from a 20 MW heat source considering pumping losses.

电厂驱动的吸附反向电渗析产生的余热发电并提供冷却

蒸汽发电厂释放出超过下面的主要能量输入作为超低温热的一半40 ^∘ Ç进入环境造成热污染。所散发的热量具有非常低的火用含量，因此很难用作另一种工艺的热量输入。吸附脱盐和反向电渗析可以通过这种热量提供动力，并将其转化为电能。因此，该系统可以减轻热污染并同时发电。这项研究将经过验证的反向电渗析模型与动态吸附脱盐模型相结合，该模型已通过这项工作中的实验数据进行了验证。实验是使用小规模的吸附脱盐和硅胶证明再生的热源温度低的可行性如进行40 ^∘ Ç。集成系统的仿真分析了不同的热集成方案，它们显示出的火用效率高达15％，能源效率高达0.55％。因此，考虑到泵送损失，该系统可以从20兆瓦的热源产生65千瓦的电能。
