The gasifier fuel gas product (stream 4) is cooled in a radiant heater, which supplies heat to the bottoming cycle. The cooled fuel gas is cleaned (stream 6) in a hot gas desulfurizer at 593 oC (1100 oF) and a polisher (stream 7) at 399 oC (750 oF) to less than 1 ppmv of sulfur prior to entering the high-pressure fuel cell (stream 8). Part of the polished fuel is expanded to 3.7 atmospheres and 220 oC (429 oF) before being sent to the low-pressure fuel cell (stream 9). Ambient air (stream 10) is compressed to 15.1 atmospheres and 409 oC (275 oF) (stream 11), and subsequently heated to 579 oC (1075 oF) prior to entering the high-pressure fuel cell cathode (stream 12). The hot clean fuel gas and the compressed ambient air are electrochemically combined within the high-pressure fuel cell with fuel and oxidant utilizations of 90 percent and 24.5 percent, respectively. The SOFC module is set (sized) to operate at 0.69 volts per cell.53 The spent fuel and air effluents of the SOFC are combusted within the module to supply heat for oxidant preheating. Unlike the natural gas case, the fuel does not require a pre-reformer with only 0.3 percent methane along with 36 percent hydrogen and 43 percent carbon monoxide. The carbon monoxide will be either water gas shifted to hydrogen or utilized directly within the fuel cell. A 52. Cold gas conversion efficiency is the ratio of the gasifier fuel gas total heating value [i.e., (heating value)(mass flow)] to that of the coal feed, [(heating value)(mass flow)]. 53. Siemens Westinghouse provided TSOFC performance values for the HP and LP conditions, which Parsons incorporated into the systems analysis. 9.6 0.7 9.6 0.7 10.3 trace 10.3 trace 10.3 trace 10.3 trace 10.3 trace 8-67PDF Image | Fuel Cell Handbook (Seventh Edition)

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
