Figure 2-4: Photo of the Sandia S-CO2 compression loop as assembled during the summer of 2008. 2.2 S-CO2 Heated but Un-recuperated Brayton Loop and Turbomachine The motor-driven compressor unit was designed so that a small turbine could be added to the rotating shaft in addition to the compressor. Because elastomers are used to seal the components on the turbomachine, the turbine hot inlet temperature must not exceed of about 560-600 K. In addition the small turbine was intended only to provide motor-assist power to reduce the motor power requirements. Still, cycle calculations indicate that power can be produced if the turbine inlet temperature is sufficiently high. Gas foil bearings can also be used. The gas-foil bearings were added because of the limited life of the ball bearings. The ball bearing race housings are instrumented with thermistors to measure the temperature. Similarly the gas-foil bearing support structure was instrumented with thermsitors as well. The switch to gas-foil bearings was made after sufficient thrust load measurements were made to assure that the actual thrust loads were within the capability of the gas-foil bearing thrust load. In January, 2009, the turbomachinery was reconfigured to run with the turbine ( Figure 2-5) using ball bearings. The compression loop was modified by adding 260 kW of heater power to form a heated, but un-recuperated, Brayton loop. This new configuration of the loop and several tests was contracted by Knolls Atomic Power Lab (KAPL). The turbine is very small (1.2 inches in diameter). It operates at low temperatures and was intended to provide about 10 kW of motor-assist power to increase the flow and pressure ratio capabilities of the loop. However, its small size allows it to produce considerable power even at low temperatures. The heated, but un- recuperated Brayton test results indicate that (when windage is excluded) the turbo-compressor is very near break-even conditions for a turbine inlet temperature as low as 60°C. Break-even, means that the turbine is producing almost as much power as the compressor uses. This is useful as it may allow future operations that make power at low temperature. 17PDF Image | Operation and Analysis of a Supercritical CO2 Brayton Cycle

Infinity Supercritical CO2 10 Liter Extractor Design and Worldwide Rights: The Infinity Supercritical 10L CO2 extractor is for botanical oil extraction, which is rich in terpenes and can produce shelf ready full spectrum oil. With over 5 years of development, this industry leader mature extractor machine has been sold since 2015 and is part of many profitable businesses. The process can also be used for electrowinning, e-waste recycling, and lithium battery recycling, gold mining electronic wastes, precious metals. CO2 can also be used in a reverse fuel cell with nafion to make a gas-to-liquids fuel, such as methanol, ethanol and butanol or ethylene. Supercritical CO2 has also been used for treating nafion to make it more effective catalyst. This NFT is for the purchase of worldwide rights which includes the design. More Info
