60 Components design system presented in Figure 2-23, corresponding to the minimum TIT for a pressure loss of 2%. However, the inlet pressure of CO2 is set to 50 bar and not to the value close to the critical pressure since the calculation procedure of ASPEN produces high deviations in the energy balance when working in this region. Both ASPEN and the present study consider similar calculation procedures since they divide the pipes in a specific number of sections and evalueate each section as an independent control volume. The number of elements for every single pipe has been set as 12. The results of the design are shown in Table 3-9.

However, Ferreira’s procedure gives a better result since the length of the tubes is closer to the one in the design done by ASPEN. The reason is the larger air side heat transfer coefficient given by the Wang correlations, leading to a lower tube length. As mentioned by these authors [8], their correlations are developed for smaller geometries, i.e., smaller tube diameter and pitch. This effect increases the air side heat transfer coefficient improving the performance of the heat exchanger and reducing its size. A schematic diagram of the cooler taken from ASPEN is presented in Figure 3-17. The only difference with the design developed in this work is the length of the tubes. J.S.

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
