The presence of elevated sulfur levels in diesel oil poses significant risks to human health, animals, the environment, vehicles, and infrastructure. Sulfur is a major contributor to particulate matter and emissions, and regulations regarding sulfur content in diesel fuel have become more stringent. Eco-friendly desulfurization techniques like biodesulfurization (BDS) are being explored, but further research is needed to fully understand the mechanism and make it more competitive in industrial applications. Combining BDS with other desulfurization technologies can potentially reduce costs and improve resource allocation.
The presence of elevated levels of sulfur in diesel oil results in an increased sulfur content in the process stream, which poses significant risks to human health, animals, the environment, vehicles, and infrastructure. Sulfur is a major contributor to particulate matter (PM) and total PM emissions. The level of pollutants emitted is correlated to the sulfur content in diesel fuel. Consequently, regulations regarding the sulfur content in crude oil products, particularly in diesel oil, have become increasingly stringent. Refiners are working to develop sulfur-free fuels with less than 10 ppm of sulfur. To address the impending threats to human health and the environment, and the impact of climate change on property, eco-friendly desulfurization techniques such as biodesulfurization (BDS) are being explored. Several bacterial species have been identified for the BDS of diesel oil, but extensive studies are needed to fully understand the mechanism. Further research on BDS is also required to make it more attractive and competitive in industrial applications. Combining BDS with other technologies for the desulfurization of diesel oil can potentially reduce operating costs and improve resource allocation, making this innovation a viable option for industry.
