Abstract: Embodiments of the present disclosure are directed towards methods of operating a heat exchanger including transferring heat from the liquid phase change material to a heat transfer fluid through a heat exchanger surface, forming a solid on the heat exchanger surface, wherein the solid is formed from the liquid phase change material, and heating the heat exchanger surface to form a liquid portion from the solid.

Abstract: A process for increasing the service life of a solar receiver by reducing the concentration of dissolved hydrogen present in a hydrogen atom containing liquid (HACL) stream including (a) contacting a HACL stream containing a first concentration of dissolved hydrogen with an inert gas stream under predetermined process conditions such that at least a portion of hydrogen in the HACL stream is transferred to the inert gas stream and a second reduced concentration of dissolved hydrogen remains in the HACL stream; and (b) passing the HACL stream having the second reduced concentration of dissolved hydrogen through the solar receiver.

Abstract: 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.
