Microbial Desulfurization of Organic Sulfur Compounds in ...

Sulfur removal from petroleum is important from the standpoint of the global environment because the combustion of sulfur compounds leads to the production of sulfur oxides, which are the source of acid rain. As the regulations for sulfur in fuels become more stringent, the existing chemical desulfurizations are coming inadequate for the "deeper desulfurization" to produce lowersulfur ......

Handbook of Refinery Desulfurization

Abstract. Desulfurization as practiced in petroleum refineries is a alytic process that is widely used to remove sulfur from petroleum feedstocks, refined petroleum products, and natural gas (Jones, 1995; Speight and Ozum, 2002; Parkash, 2003; Hsu and Robinson, 2006; Mokhatab et al., 2006; Gary et al., 2007; Speight, 2014).The purpose of removing the sulfur is to reduce the emissions of ......

Handbook of Refinery Desulfurization

Handbook of Refinery Desulfurization describes the operation of the various desulfurization process units in a petroleum refinery. It also explains the processes that produce raw materials for the petrochemical industry. It illustrates all the possible processes to lower the sulfur contents in petroleum and its fractions to decrease emissions of sulfur oxides....

"Deep desulfurization of petroleum feedstocks by selective ...

The easy regeneration of these adsorbents makes them attractive for the deep desulfurization of petroleum feedstocks. The ability of Ru(NH3)5(H2O) 2+ to bind to thiophenes has been used in an extraction process in which a solution of Ru(NH3)5(H2O) 2+ in 70% DMF and 30% H2O is contacted with a simulated petroleum feedstock (45% toluene/55% hexanes) containing 400 ppm of DBT. Five ....
