for both heat source and sink). In the current preliminary simulation following assumptions were made: 1. All the ORC heat exchangers i.e. evaporator, pre–heater and condenser, are 100% efficient. 2. The quality of refrigerant out of the evaporator in the ORC system is controlled. 3. The quality of liquid out of pre–heater and condenser are saturated liquid. 4. The isentropic efficiency of screw expander and pump (within the ORC system) are taken to be constant at 78% and 70% respectively. Assumptions will affect the system performance characteristics. If the simulation results don’t match the published or measured performance characteristics of the real system, test plan need to be designed to determine which assumptions need to be changed. The model can be modified easily, once better performance characteristics of components are obtained from experiment. Figure–1: Schematic of Organic Rankine Cycle System In simulating the ORC system performance explicit formulae for heat transfer coefficients of refrigerant on one side of the heat exchanger and water on other side of the heat exchanger should be known. Generally the heat transfer coefficient of a fluid is expressed in terms of its thermodynamic and transport properties. The heat transfer coefficient also depends on the geometry of heat exchanger, material of construction etc. All the heat exchangers considered in the present case are plate heat exchangers (PHE). A widely accepted expression for heat transfer coefficient of single phase fluids in a plate heat exchanger is given by Muley and Manglik [6]. In ORC system this expression is used for calculating heat transfer coefficient of hot water and cold water in evaporator and condenser respectively and heat transfer coefficient of hot water and refrigerant in pre–heater. In all the above cases of calculating heat transfer coefficient the fluid thermo–physical properties were taken at average fluid temperature. 15PDF Image | Optimizing Heat Recovery Systems for Power Generation in Rural AK

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
