| Popis: | Multi-effect distillation (MED) desalination system always faces the inevitable fouling problem, which leads to a decrease in fresh water production and restricts its long-term efficient operation. This study focuses on improving the system's operation benefits in the full cycle. Firstly, an asymptotic model for fouling accumulation is added to a MED-TVC model, which takes into account the influence of operating conditions on the fouling rate. Subsequently, the impact of fouling accumulation on the operating state of the system is analyzed in the whole cycle, indicating the decrease of operating benefits. Finally, the full cycle operation optimization method is applied for the purpose of reducing motive steam consumption as well as meeting fresh water demand using control vector parameterization strategy. The result shows a significant reduction in motive steam consumption while maintaining fresh water production capacity, which confirms that full cycle optimization has a considerable effect on dealing with fouling problem in MED desalination systems. |
