Desulfurization of oils can be done in two main ways. The first is similar to natural gas desulfurization, which is typically only used if the oil has a relatively low (less than 50ppm) sulfur level to begin with. The second method is microbial desulfurization, which uses the Rhodococcus organism to remove sulfur compounds, reducing air ...

What is Flue Gas Desulfurization Gypsum? Flue gas desulfurization gypsum (FGDG) is an industrial byproduct generated during the flue gas desulfurization process in coal-fired power plants. Flue gas desulfurization systems have been used to limit the release of sulfur dioxide from coal-fired power plants since the late 1960s, but in the past decade the …

Desulfurization is a technology used to separate SO 2 from its emitting sources such as exhaust flue gases of fossil-fuel power plants, oil refineries, etc. The crucial requirement to decrease sulfur loading in fuels to nearly zero content is imposed by mandatory environmental and health protocols as well as the accurate tolerance needed for their use in fuel applications.

Flue gas desulfurization (FGD) is one of the most effective emission control technologies used in power plants, and it plays a pivotal role in reducing SO 2 emissions 13. Several FGD systems have ...

When IL ([BPy]HSO 4) is used as PTC, and the condition are: temperature is 60 °C, time is 60 min, H 2 O 2 /sulfur molar ratio (O/S) is 4, the desulfurization rate reaches the maximum (93.3%), and the desulfurization of …

Researchers at the startup have developed two catalytic adsorbents — AdE-Sorb and AdE-Sulfur — for ultra-deep desulfurization of diesel. Ultra-deep desulfurization reduces the sulfur content in diesel to less than 15 ppm.

In addition, the photocatalytic desulfurization mechanism is also introduced with the . OH and . O 2 − radicals as main active species. Finally, some perspectives on the photocatalytic desulfurization are provided, which can further optimize the desulfurization efficiency and guide future photocatalyst design.

Post-combustion flue gas desulfurization and denitrification technologies are essential in achieving the full compliance of fine particulate matter (PM2.5, aerodynamic diameter less than 2.5 μm) air quality standards by 2030 in China as sulfur dioxide (SO2) and nitrogen oxides (NOX) are the main precursors of PM2.5. Some studies have addressed the …

Desulf-Tek specializes in engineering and manufacturing customized mobile fuel desulfurization systems that can easily be transported and quickly commissioned to provide a powerful desulfurization capability at any location around the globe

Using AdE-Sorb, desulfurization without hydrogen would cost $0.034/gal and reduce sulfur content of diesel from 600 ppm to less than 15 ppm for a 6,000-bpd refinery. In addition, this process would reduce CO 2 emissions by about 320 tons/day. Independent Oil Corp. in Canada has recently tested this process in one of its pilot facilities.

The current industrial method for removal of sulfur from fuels is hydrodesulfurization (HDS), which is a high temperature, high pressure catalytic process. This makes HDS a very costly option for deep desulfurization. Moreover, HDS is not effective for removing heterocyclic sulfur compounds such as dibenzothiophene (DBT) and its derivatives, especially 4,6-dimethyldibenzothiophene …

The meaning of DESULFURIZATION is the removal of sulfur or sulfur compounds (as from coal or flue gas).

1 Introduction. Hot metal desulfurization serves as the main unit process for removing sulfur in blast-furnace-based steelmaking. Hot metal desulfurization is commonly conducted in a ladle or a torpedo car, 1 using a desulfurization reagent that is either injected into the metal bath or added on top of it. 2 From the thermodynamic point of view, the fundamental requirement for the ...
