International Journal of Advances in Engineering & Technology, Jan. 2013. ©IJAET ISSN: 2231-1963 Mass, energy and exergy balances for any control volume at steady state with negligible kinetic and potential energy changes can be expressed, respectively, by åm=åm (1) Q - W = å mouthout - å m h (2) in in Eheat - W = å Eout - å Ein + å ED (3) in out are the net heat input and work output, m where Q enthalpy, the subscripts in and out stand for inlet and exit, E D Eheat and W is the net exergy transfer by heat at temperature T, which is given by ç E = 1- ÷Q (4) is the mass flow rate of the fluid, h is the is the rate of exergy destruction, and æ T0÷ö heat åç ç ÷ èTø where T is the temperature at which heat transfer takes place. The specific flow exergy and the rate of total exergy are given by e = h - h0 - T0 (s - s0 ) (5) E = me (6) where the subscript 0 stands for the restricted dead state and T0 is the dead state temperature. The energy and exergy efficiencies are generally defined as hI = energy in products () (7) (9) (10) (11) total energy inputs hII = energy in products () total energy inputs (8) 3.2. Performance evaluation In general, the first-law efficiency of a geothermal power plant may be expressed as [7]. m h h geo geo o Net power Wnet,orc = WT,orc - WP,orc The first-law efficiency may be expressed based on the heat transfer to the ORC hI,1 = Wnet,orc Q in ,orc Wnet I,1 Using the exergy of geothermal water as the exergy input to the plant, the second-law efficiency of a geothermal power plant can be defined as [7]. h = Wnet,orc = Wnet,orc (12) m [(h-h)-T(s-s)] in orc32032 II,1 E The total exergy destruction rate in the cycle is determined from ED =ED,P +ED,E +ED,T +ED,C +ED,CA (13) For the sake of comparison, it is better to use the exergy destruction ratio, YD,i, which is the exergy destruction rate in a component compared to the exergy rate of the fuel provided to the overall system [8].

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
