The design mass flow rate is 3.53 kg/s. The Sandia test compressor, operating at 75,000 RPM and 3.53 kg/s with inlet conditions of 7.69 MPa and 305 K achieved a pressure ratio of 1.8 and a total-to-static efficiency of 66.0 % [Wright et al., 2008]. The steady-state operating speed is really a lower value than 75,000 RPM. It is actually closer to 45,000 RPM. The performance maps produced by RGRCMS are reasonably accurate considering that dimensions were determined by looking at a photograph of the test compressor. Continued operation of this test compressor and input of more precise geometry will yield more data and eventually RGRC can be effectively benchmarked. Currently, the exact dimensions of the impeller are not available for release, nor are tabulated data. 3.6 Chapter Summary A mean-line compressor code was developed using the NIST fluid property polynomials as a means of sizing and estimating performance for S-CO2 compressors to be used in the recompression cycle. This code produces results for single and multi-stage compressors, estimating losses based on experimental correlations. It is a first step in designing actual compressors. The geometry of the compressor impeller can be manipulated by the user in a single input file and the code performs sizing of the impeller and related diffuser to achieve the desired pressure ratio at the design point. Off-design performance estimation is automatic for the resulting design. RGRC produces a performance map for the stage in a single output file with the important geometrical parameters. RGRC also produces an output that can be used with other stage outputs in the multi-stage code, RGRCMS. 78 Total-to-Static EfficiencyPDF Image | Supercritical Carbon Dioxide Cycle Analysis

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
