Temperature-enhanced PRO (T-PRO) has been demonstrated to enhance the PRO performance via one system/module-scale mathematical model, but its techno-economic availability is still uncertain. As such, T-PRO was experimentally investigated in the lab-scale setup and its economic benefit was evaluated via utilizing solar energy as the thermal source. The experimental investigation showed that both optimal operating pressure and corresponding water flux increased from 12 bar and 3.74 LMH to 16 bar and 7.94 LMH when the operating temperature increased from 20 to 30 °C, thereby rendering an increase in power density from 1.25 to 3.53 W/m² by 1.82 times and validating that the contribution of high operating temperature on energy generation was derived from increased operating pressure and water flux. Furthermore, the economic feasibility of T-PRO was assessed via one developed economic evaluation model based on solar linear Fresnel collectors. Evaluation results showed that the economic benefit of T-PRO could not cover the expenditure of thermal power, thus a standalone T-PRO system powered by solar energy was not feasible under current conditions. But, if these high-temperature and low-salinity solutions discharging from T-PRO can enter some thermal desalination systems, additional thermal power in T-PRO would reduce the thermal input in a further thermal desalination system. Therefore, T-PRO powered by solar energy must be integrated with thermal desalination technologies under the high cost of solar energy.

已经证明温度增强型PRO（T-PRO）可通过一个系统/模块规模的数学模型来提高PRO的性能，但是其技术经济可用性仍不确定。因此，在实验室规模的装置中对T-PRO进行了实验研究，并通过利用太阳能作为热源评估了其经济效益。实验研究表明，当工作温度从20°C升高到30°C时，最佳工作压力和相应的水通量从12 bar和3.74 LMH分别增加到16 bar和7.94 LMH，从而使功率密度从1.25增加到3.53 W /米²降低了1.82倍，并验证了较高的工作温度和水通量可得出较高的工作温度对能量产生的贡献。此外，通过以下方式评估了T-PRO的经济可行性：一种基于太阳能线性菲涅尔收集器的发达经济评估模型。评估结果表明，T-PRO的经济利益无法覆盖火电的支出，因此，在当前条件下，由太阳能驱动的独立T-PRO系统是不可行的。但是，如果从T-PRO排放的这些高温和低盐溶液可以进入某些热淡化系统，则T-PRO中的额外热能将减少另一个热淡化系统中的热输入。因此，在太阳能的高成本下，由太阳能驱动的T-PRO必须与热脱盐技术集成在一起。
