Title: Power generation from lng
Inventor: KOOY RICHARD JOHN
IPC: F17C9/04
Filed: 1991-05-30
Granted: 1999-06-15
Abstract: LNG is pumped to high pressure, vaporized, further heated and then expanded to create rotary power that is used to generate electrical power. A reservoir of carbon dioxide at about its triple point is created in an insulated vessel to store energy in the form of refrigeration recovered from the evaporated LNG. During peak electrical power periods, liquid carbon dioxide is withdrawn therefrom, pumped to a high pressure, vaporized, further heated, and expanded to create rotary power which generates additional electrical power. The exhaust from a fuel-fired combustion turbine, connected to an electrical power generator, heats the high pressure carbon dioxide vapor. The discharge stream from the CO2 expander is cooled and at least partially returned to the vessel where vapor condenses by melting stored solid carbon dioxide. During off-peak periods, CO2 vapor is withdrawn from the reservoir and condensed to liquid by vaporizing LNG, so that use is always efficiently made of the available refrigeration from the vaporizing LNG, and valuable peak electrical power is available when needed by using the stored energy in the CO2 reservoir.

Abstract: PURPOSE: An apparatus and a method for extracting ultrasonic waves are provided to develop an ultrasonic vacuum food technology process for preventing the loss of effective component and the increase of toxicoid, and to provide a manufacturing process of child-care food and various favorite food. CONSTITUTION: The apparatus for extracting ultrasonic waves comprises an ultrasonic oscillator(3,11) installed in a pipe(10) and an ultrasonic vacuum extraction tank, and a solid pump device(6) for circulating the process liquid. The ultrasonic waves oscillator installed in the ultrasonic vacuum extraction tank applies the ultrasonic waves to a process liquid(14) received in the tank by using a concentric corrugated thin vibrating plate(4) to cause agitation, release, homogenization reactions by cavitation, and to break active cell membrane. According to the apparatus and the method, various chlorophyllous extract, chlorophyllous sweet stuff, extracted medicine and so on are developed.
