Supercritical CO2 is recognized as a promising working fluid for next-generation of high temperature power cycles. Nevertheless, the use mixtures with heavier dopants emerging alternative to supercritical cycles in recent years air-cooled systems hot environments. Accordingly, this work presents an experimental campaign assess thermodynamic behaviour CO2+SiCl4 mixture be used high-temperature applications, conducted laboratories CTP Mines Paris PSL. At first, bubble conditions are measured...
Silicon Tetrachloride (SiCl4) is proposed as a new potential working fluid for high-temperature Rankine Cycles. The capability to overcome the actual thermal stability limit of fluids commercially employed in state-of-the-art Organic Cycles (ORC) demonstrated by static and material compatibility tests. Experimental test proves its thermo-chemical with conventional stainless-steel alloy (AISI 316L) up 650 °C. A preliminary analysis performed optical microscope on AISI 316L cylinder, after...
This work analyses the integration of concentrated solar power plants based on innovative sCO2 cycles and transcritical CO2-based mixtures with thermal desalination adopting conventional MED technology. In these cogeneration plants, all heat rejected from cycle is exploited by system, avoiding any parasitic electric consumption fans air-cooled rejection unit. The layout proposed exploits both latent effects, 3 to 8, sensible match at best temperature level which available cycles, delivered...
Carbon dioxide binarFIGy mixtures are increasingly considered as working fluids in transcritical power cycles, due to the capability perform liquid-phase compression even at high environmental temperatures. However, a robust thermodynamic model is essential for optimal and reliable design conditions. It widely recognized that fine-tuning equation of state with experimental vapor-liquid equilibrium data mixture significantly enhances its reliability. In this work, new apparatus dedicated...

Abstract CO2 blends provide tremendous advantages when used as a working fluid in transcritical power cycles with respect to pure CO2. The benefits become especially apparent if coupled concentrated solar since increasing the critical temperature of blend allows dry condensing at high ambient temperatures locations radiation. One key cycle component is cooler, which this work designed an air-cooled condenser MATLAB in-house code. internal, condensation heat transfer model paper relies on...
Transcritical cycles working with CO 2 ‐based mixtures gain considerable attention due to thermodynamic efficiency compared pure sCO in hot environments. Previous literature works prove that the adoption of provides a reduction levelized cost electricity concentrated solar power applications and medium–high temperature heat recovery. However, for techno‐economic analysis exchanger design, proper evaluation transport properties cycle conditions is necessary. Herein, it deals models assess...
