Performance Characteristics of Compressor 2 for the Off-design-points flow rate were determined from the operation conditions; the maximum diameter and the head of the compressor were determined to maximize the efficiency, as seen in the diagram for the specific diameter and the specific speed. As a result of the iterative calculations, and based on the design parameters in Table 3, the stages of the two compressors (Compressor 1, Compressor 2) were determined as two and three, respectively. From Figure 3, the efficiency of the compressor was estimated during the process of the conceptual design to be more than 80% for the S-CO2 Brayton cycle coupled to the KALIMER-600. The diameter was estimated to be within 1 m for the two compressors. The performance analysis code, named COMP1D, for a centrifugal compressor for the S-CO2 cycle, was developed on the basis of the meanline analysis method, which is a one-dimensional analysis method. Since a sensitive loss model is required in order to include the effect of the impeller configuration and the flow path parameter, the loss model suggested by Oh was used to develop the code [11].

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
