Sylvain Quoilin Chapter 2 : Low temperature heat recovery A quick review of the literature about low temperature Rankine cycles gives an idea of the usual working fluids used in ORC systems. Table 1 and 2 give the main characteristics of those fluids, from an environmental and thermodynamic point of view. Refrigerant R11 R22 R113 R123 R134a R245fa R717 (ammonia) R601 (npentane) R601a (isopentane) Atmospheric ASHRAE Level lifetime of safety 45 A1 12.0 A1 85 A1 1.3 B1 14.0 A1 7.6 B1 B2 ODP Net GWP 100 year (2102) 1 3660 0.034 1710 0.90 5330 0.012 53 ~0 1320 ~0 1020 ~0 <1 ~0 ~20 ~0 ~20 Phase out Year 1996 2020 1996 2030 Table 1: Environmental data for historical, current, and candidate chiller refrigerants A first selection can be achieved among those fluids given the working temperature range. The application envisaged in the present work have a heat source temperature ranging from 100 to 200 °C and an heat sink temperature ranging from 10 to 50 °C. It is obvious that R22 and R134a can be eliminated, their temperature range being too low (see table 2). In the same manner, water, benzene, toluene and pxylene have a too high temperature range and can be eliminated as well. From an environmental point of view, R11 and R113 have a very high ozone depleting potential (ODP), and were phased out in 1996 by the Montreal protocol. Therefore, they won't be taken into account in this work. 16PDF Image | Modeling of a Low Temperature Rankine Cycle for Small Scale Cogen

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
