Abstract

This study investigates performance and economic evaluation of an annual adsorption desalination system utilizing several activated carbons (raw Maxsorb III, Maxsorb III/HCl, Maxsorb III/(NH₄)₂CO_3, and Maxsorb III/CaCl₂) in the context of Egyptian climatic conditions. A comparison is made between the performance of the adsorption desalination system with and without heat recovery from the condenser/evaporator. MATLAB and TRNSYS are used to carry out the model using climatic data of the hot region. The results revealed that the Maxsorb III/CaCl₂ system exhibits superior performance, whereas the raw Maxsorb III demonstrates the least efficacy among the investigated adsorbent materials. The results indicated that the Maxsorb III/CaCl₂ system provided the most significant specific daily water production value of 25.4 m³/ton without heat recovery, while it could be increased to (36.7 m³/ton) with heat recovery, achieving a gained output ratio of 0.76 at the optimal cycle time 700 s. The Maxsorb III/CaCl₂ system had the most cost-effective method for producing desalinated water. Using waste heat instead of solar energy leads to reduced expenses. The costs for cycles without heat recovery in June were 4.62 and 0.9 $/m³ for solar energy and waste heat, respectively. The cost of heat recovery cycles decreased to 4.25 and 0.65 $/m³.

埃及气候条件下利用改进型Maxsorb III吸附剂的太阳能吸附脱盐冷却系统的成本分析

本研究考察了在埃及气候条件下，使用几种活性炭（生Maxsorb III、Maxsorb III/HCl、Maxsorb III/(NH4)2CO3和Maxsorb III/CaCl2）的年度吸附脱盐系统的性能和经济评价。比较了带冷凝器/蒸发器热回收和不带冷凝器/蒸发器热回收的吸附式海水淡化系统的性能。利用MATLAB和TRNSYS对热区气候数据进行建模。结果表明，Maxsorb III/CaCl2体系表现出较好的吸附性能，而原料Maxsorb III的吸附效果最差。结果表明，Maxsorb III/CaCl2系统在不进行热回收的情况下，比日产量最高，为25.4 m3/t，而在进行热回收的情况下，比日产量可提高到36.7 m3/t，在最佳循环时间为700 s时，比日产量可达到0.76。Maxsorb III/CaCl2系统是生产淡化水最具成本效益的方法。用余热代替太阳能可以减少开支。6月份，太阳能和废热的无热回收循环成本分别为4.62美元/立方米和0.9美元/立方米。热回收循环的成本降至4.25美元/立方米和0.65美元/立方米。
