·Due to the most recent environmental requirements wide desulfurization has become an increasingly important way to obtain ultra clean fuels for transportation of less than 15 ppmw of sulfur such as diesel gasoline and jet fuel as a result of the strict requirements for transportation fuels
In 1990 the total utilization of FGDS in the USA as a percentage of production accounted for % Collins 1992 in 1992 it was reported to be 2% Tyson 1994 and in 1996 1997 it reached 7% Butalia and Wolfe 1999; Stewart 1999 while the utilization of other CCW accounted in total for % of production in 1992 and remained at
Desulfurization is the process to solidify the sulfur in the coal thereby preventing the generation of SO 2 during coal combustion [76 77] Currently various desulfurization methods have been proposed and implemented in power generation [77 81] Generally desulfurization methods can be divided into three categories namely pre combustion
·The extractive desulfurization has been found to be one of the most effective way for desulfurization of the liquid fuels The major aspects which affects the desulfurization are the temperature oil IL/DES mass ratio extraction time initial S Content mutual solubilities multiple cycles and regeneration of the used solvents in the EDS process
·The amount of sulfur in crude oil has become a global concern because high levels of sulfur in refinery streams cause catalysts to become inactive and…
·Here the authors show that the global diffusion of flue gas desulfurization technology was very fast at times especially for retrofit and even after materiality but strongly depended on regulation
·Flue gas desulfurization FGD systems using lime or limestone as the chemical reagent are widely used throughout the world for SO 2 emissions control at coal fired power plants Ammonia based
Currently desulfurization occurs in a process called Hydro Desulfurization that uses hydrogen gas high temperatures 300 to 400 degrees Celsius and high pressures 30 to 130 atmospheres to modify sulfur bearing compounds so they can be removed The catalyst serves the dual purpose of a catalyst and a transfer agent thus increasing the
·1 Introduction Sulfur dioxide SO 2 is one of the primary pollutants in flue gas produced by the metallurgical and chemical industries [1] In some metal smelters ammonia desulfurization to prepare ammonium sulfate NH 4 2 SO 4 is an effective way to realize flue gas obtained product NH 4 2 SO 4 is a necessary chemical by product
·Here the authors show that the global diffusion of flue gas desulfurization technology was very fast at times especially for retrofit and even after materiality but strongly depended on regulation
ODS is a promising desulfurization technology as its low production cost Oxidative desulfurization process principles are as follows sulfur and oxygen have a similar electronegativity but oxygen is slightly higher sulfur and carbon bond almost has Many oxidizing agents have been reported in ODS process and H 2O 2 is the main one After
·FeSO 4 ·7H 2 O as catalyst Ca OH 2 as the desulfurization agent and NH 3 as the denitration agent The by product is CaSO 4 and a small amount of CaSO 3
