Supercritical Carbon Dioxide Circulated EGS Combined with IGCC in New Mexico serves to reduce the remaining amount of CO in the synthesis gas stream so that an overall conversion of 97% is reached (Black, 2010). 4.4.3 Mercury Removal The mercury removal section operates at a temperature of 35°C thus the shifted synthesis gas must be cooled down before passing through a fixed packed bed reactor that contains sulfur- impregnated activated carbon (Black, 2010). The excess heat is extracted and transferred to the HRSG in the form of high and medium pressure steam. At high pressures of 6.2MPa, the activated carbon removes 95% of the mercury in the raw, shifted synthesis gas stream. The bed life is estimated to be between 18 and 24 months but is dependent on the actual amount of mercury contained in the coal. Generally over the carbon bed life, the weight percent increase from mercury removal will be 0.6-1.1wt% however the activated carbon could absorb up to 20wt% maximum but with decreasing rate of ability of absorptivity (Black, 2010). 4.4.4 Acid Gas Removal Acid gas removal (AGR) serves to removes acidic gases such as H2S and CO2 out of the raw synthesis gas stream (Chiesa, 1999). Chemical and physical solvents provide the means of accomplishing AGR, but chemical solvent pose an issue of separation after absorption, thus the physical solvent of Selexol was chosen. Selexol is polyalkylene glycol dimethyl ether (PGDE) (Song, 2009). The more common Rectisol process was not chosen due to the energy requirements to chill the methanol down to temperature of -40 to -60°C (Robinson, 2010). Prior to AGR, the raw synthesis gas stream is cooled down to approximately 25° C and passed through two consecutive physical absorption columns (Song, 2009). The amount of acid gases absorbed into the physical solvent is based on Henry‘s Law, meaning that at constant temperatures the amount of a given gas that dissolves into a liquid is directly proportional to the acid gases partial pressure (Klara, 2009). The physical absorption of acid gases into Selexol is favored at lower temperatures (25°) and high pressures (5.1MPa) (Klara, 2007). The reclamation process of procuring the H2S and CO2 requires a series of flash drums where the pressure is ―flashed‖ or decreased rapidly thus decreasing the solubility of the physical solution in which the acid gases were captured (Black, 2010). A flow diagram of the removal of acid gases and recovery of the Selexol can be observed in figure 42 Penn State University | 4.4 Gas Cleaning Unit 69PDF Image | GREAT NECK WATER POLLUTION CONTROL DISTRICT NASSAU COUNTY, NEW YORK MICROTURBINE INSTALLATION FEASIBILITY STUDY

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
