Abstract
Official abstract text for this publication.
A rotary liquid piston compressor and a power generation system including a first fluid loop. The first fluid loop includes a pump that circulates a liquid. A second fluid loop that generates power by circulating a supercritical fluid. The second fluid loop includes a turbine that rotates and powers a generator as the supercritical fluid flows through the turbine. A rotary liquid piston compressor fluidly coupled to the first fluid loop and the second fluid loop. The rotary liquid piston compressor exchanges pressure between the liquid circulating in the first fluid loop and the supercritical fluid circulating in the second fluid loop.
First claim
Opening claim text (preview).
The invention claimed is: 1. A system comprising: a first fluid loop, the first fluid loop comprises: a pump configured to circulate a liquid; a second fluid loop configured to generate power by circulating a supercritical fluid, the second fluid loop comprises: a turbine configured to rotate and power a generator as the supercritical fluid flows through the turbine; and a first rotary liquid piston compressor fluidly coupled to the first fluid loop and the second fluid loop, wherein the first rotary liquid piston compressor is configured to exchange pressure between the liquid circulating in the first fluid loop and the supercritical fluid circulating in the second fluid loop. 2. The system of claim 1 , wherein the supercritical fluid comprises carbon dioxide, helium, supercritical steam, or an organic fluid. 3. The system of claim 1 , wherein the liquid is water. 4. The system of claim 1 , wherein the first fluid loop comprises an evaporator chamber downstream from the first rotary liquid piston compressor, and wherein the evaporator chamber is configured to separate the supercritical fluid from the liquid as the supercritical fluid changes phases into a gas. 5. The system of claim 4 , wherein the first fluid loop comprises an orifice or pressure control valve upstream from the evaporator chamber. 6. The system of claim 1 , wherein the second fluid loop comprises a recompressor. 7. The system of claim 6 , wherein the recompressor comprises a second rotary liquid piston compressor. 8. The system of claim 1 , wherein the second fluid loop comprises a first recuperator or a first regenerator downstream from the first rotary liquid piston compressor. 9. The system of claim 8 , wherein the second fluid loop comprises a second recuperator or a second regenerator downstream from the first recuperator or the first regenerator. 10. The system of claim 1 , comprising a second rotary liquid piston compressor and a third rotary liquid piston compressor, wherein the first rotary liquid piston compressor is configured to transfer a first portion of the supercritical fluid to the second rotary liquid piston compressor and a second portion to the third rotary liquid piston compressor.
