Chapter 6: Case studies Figure 85: Overall efficiency for different working fluids. limit is applied, the maximum overall efficiency is 7.5% for Solkatherm and 7% for HFC-245fa. Additional parameters to the sole efficiency must be taken into account when comparing working fluids. Table 26 shows the more relevant cycle parameters for a few selected optimal points. The bold characters indicate the most advantageous value for each column. If Solkatherm is the most efficient fluid, it is also the one requiring the biggest expander, with a suction swept volume (in expander mode) of 180.7 cm3 for the second stage of expansion and an evaporating temperature of 150°C. HFC-245fa on the contrary shows very advantageous swept volumes, which could reduce the cost of the system. n- pentane must be run at very high temperature to show a good efficiency. Its required evaporator area is advantageous, but the required recuperator area is very high due to the low density and the very high pressure drops in the low-pressure vapor.

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
