A major concern among the environmental agencies includes the emission of sulfurous gas
into the environment. Consequently, the oil agencies are in constant search of alternative …

Sulfur oxide (SO2) and hydrogen sulfide (H2S) are considered as one of the major air
pollutants in the world today. In addition, high sulfur levels in petroleum distillates can …

To reduce the harm caused to the environment by fuel combustion and meet the
increasingly stringent emission standards, the sulfur content of fuels should be reduced …

Environmental concerns have given a great deal of attention for the production of ultra-low-
sulfur fuels. The conventional hydrodesulfurization (HDS) process has high operating cost …

Microbial desulfurization or biodesulfurization (BDS) is an attractive low-cost and
environmentally friendly complementary technology to the hydrotreating chemical process …

The utilization of nutrients in sewage sludge partly alleviates the economic and
environmental constraints, and the composting process has been proved a cost-efficient and …

This is the third in a series of independent research papers attempting to improve the quality
of descriptive data and analysis of tailings facility failures globally focusing on the relative …

Refineries process a number of gas oils such as straight run gas oil (SRGO), light cycle gas
oil, coker gas oil and visbreaker gas oil for producing a common gas oil pool to be used as a …

Thiophenic compounds viz. dibenzothiophene (DBT) and its derivatives present in fossil
fuels contribute significantly to air pollution. Here we report for the first time the efficacy of a …

Although conventional oil refining process like hydrodesulfurization (HDS) is capable of
removing sulfur compounds present in crude oil, it cannot desulfurize recalcitrant …
