1.6.2 Closed-Cycle Cooling Closed-cycle methods of heat dissipation include cooling ponds, spray ponds and canals, mechanical and natural draft evaporative cooling towers, and mechanical and natural draft dry cooling towers. In each case, water is recirculated between the condenser and the heat dissipator. Cooling ponds are used widely in regions where extensive land areas are available for surface heat dissipation. A 1000 MW station requires about 1000 acres of water surface. Spray systems can be added to increase the heat dissipation. However, the water loss from evaporation and drift can be significant. In addition, the performance of clusters of spray modules has not been as good as the performance predicted on the basis of individual unit measurements. Cooling ponds and spray canals have also been used in conjunction with once-through cooling schemes. In this manner, a portion of the heat may be dissipated in the pond before the cooling water is discharged to an adjacent body of water. Most cooling towers constructed for power plants above 500 W have been of the natural draft wet, or evaporative type -- large hyperbolic towers that cool by creating a natural draft of air which passes through water droplets sprayed by nozzles withinthe tower. Cooled water collects in a pool at the base of the tower. The lowest water temperature in these towers-will always be above the wet-bulb temperature of the surrounding air. A natural-draft tower for a 1000 MW nuclear unit would be 600 feet at the base and 500 feet in height. A source of make-up water must be available to replace that lost by evaporation and drift and to provide blow-down water to prevent buildup of chemical residue by evaporation. Since the cooling is primarily by 22PDF Image | WASTE HEAT MANAGEMENT IN THE ELECTRIC POWER INDUSTRY

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
