| Abstract: Various technologies pertaining to tuning composition of a fluid mixture
in a supercritical Brayton cycle power generation system are described
herein. Compounds, such as Alkanes, are selectively added or removed from
an operating fluid of the supercritical Brayton cycle power generation
system to cause the critical temperature of the fluid to move up or down,
depending upon environmental conditions. As efficiency of the
supercritical Brayton cycle power generation system is substantially
optimized when heat is rejected near the critical temperature of the
fluid, dynamically modifying the critical temperature of the fluid based
upon sensed environmental conditions improves efficiency of such a
system. |
