A thermodynamic cycle such as an organic Rankine cycle system, utilizing a lubricant and a working fluid, for a machine in which pressurized gaseous working fluid is expanded to a lower pressure level and the energy from the fluid expansion is transformed into mechanical rotation energy; the lubricant includes a polyalkylene glycol based lubricant composition and the working fluid includes a mixture of alcohol and water.

Thermodynamic cycle system

A process and an apparatus () for producing a superheated working fluid from a concentrating solar plant. More specifically, the process and apparatus produce superheated steam. The apparatus is designed such that it can use more than one heat transfer medium to produce the superheated working fluid. A first heat exchanger system () is designed to use the heat of a first heat transfer medium in order to preheat, evaporate and superheat a working fluid in a power generating working cycle (). A second heat exchanger system () is designed to use the heat of a second heat transfer medium to superheat the working fluid in cycle ().
