6th International Conference on Pumps and Fans with Compressors and Wind Turbines IOP Publishing IOP Conf. Series: Materials Science and Engineering 52 (2013) 042018 doi:10.1088/1757-899X/52/4/042018 comparison, Siloxane1 can get a higher net power output. It is probably because its critical pressure is higher than the other two working fluids. Fig.6 displays the exergy efficiency (ηexg) of the CORC system at different P referring to the three max h different working fluids. It shows that the trend of ηexg is almost a straight line up with the increase of P . Furthermore, Siloxane1 gets the minimum exergy efficiency comparing to Siloxane2 and max h Siloxane3 at the same P , which is adverse to Siloxane1 in contrast to the previous comparison max h between Siloxane1 and Siloxane2 ,Siloxane3. Fig. 7 reports the global thermal efficiency of DE-CORC combined systems (ηglo) at different P . max h Three curves are not strict parabola shape. ηglo always gets the same value in some small ranges of P . There is still maximum ηglo for each working fluid. Siloxane1 gets the maximum ηglo value of max h 46.21% in the range of 11-13MPa for P . Siloxane2 gets the maximum ηglo value of 45.61% in the max h range of 4-7.5MPa for P . Siloxane3 gets the maximum ηglo value of 45.72% in the range of 6.5- max h 8.5MPa for P . Therefore, when choosing the optimal P , the relatively low P can be chosen to maxh maxh maxh get the maximum ηglo for the DE-ORC combined system. Siloxane1 shows a higher global thermal efficiency, which has the same result as Fig.5. Siloxane1 gets a better performance in comparison to the other two working fluids. The combined cycle could recover the multiple grades fully. In this paper, we define the ratio of heat recovery as: Ratio=100*Qrecovered/Qmax (13) wherein, Qmax means the maximum possible recovery heat, which are the heat releasing from inlet temperature to 120°C for of EGR and exhaust, the heat releasing from inlet temperature to 25°C for CAC and the heat releasing from inlet temperature to 70°C for coolant. Taking Siloxane2 system for example, table.4 shows the heat recovery ratio of the four parts waste heat at various Pmax,h. As shown, using the CORC could recover about 95.9% of EGR waste heat, 97.5% of exhaust waste heat, 78.9% of CAC waste heat and 100% of coolant waste heat. Figure 5. Variation of Pnet with P Figure 6.

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
