提出了一种超临界有机朗肯循环(SORC)驱动的海水反渗透系统(SORC-RO)。该系统既适用于太阳能等循环热源，也适用于余热或地热等直通式热能。采用两种最高温度为150°C的低品位热源对SORC-RO系统进行了分析，并与传统的有机朗肯循环驱动的海水反渗透系统(ORC-RO)进行了比较。结果表明，SORC-RO系统能够利用不同的热源，并提供相对稳定的性能。如果热源为废热，SORC-RO系统可以充分利用热源，减少对环境的热污染。根据流体的临界压力和温度，提出了一份适用于使用低于150°C的低品位热源的SORC-RO系统的工作流体的综合清单。
A supercritical organic rankine cycle (SORC) driven seawater reverse osmosis (RO) system (SORC-RO) is proposed. The proposed system is suitable for using both recirculating heat sources such as, solar thermal, and once-through thermal energy resources, such as, waste heat or geothermal. The SORC-RO system is analyzed using two types of low-grade heat sources with a maximum temperature of 150°C and compared with the conventional organic rankine cycle driven seawater reverse osmosis system (ORC-RO). The results show that the SORC-RO system is able to make use of different heat sources and provide relative stable performance. If the source is waste heat, the SORC-RO system could make full use of the heat source and reduce thermal pollution to the environment. A comprehensive list of working fluids candidates for the SORC-RO system using low-grade heat sources less than 150°C is proposed based on the critical pressure and temperature of the fluids.
