Desulphurization: Methods and Importance for Cleaner Burning Fuels

Desulphurization is a process of removing sulfur compounds from fossil fuels, such as coal and oil, to reduce their sulfur content. The goal of desulphurization is to produce cleaner-burning fuels that emit fewer harmful pollutants when burned.

There are several methods used for desulphurization, including:

1. Fuel switching: This involves replacing high-sulfur fuels with lower-sulfur alternatives, such as natural gas or renewable energy sources.
2. Flue gas desulfurization (FGD): This process involves removing sulfur dioxide from the flue gases produced by power plants and other industrial facilities that burn fossil fuels.
3. Hydrodesulfurization (HDS): This is a chemical process that removes sulfur compounds from crude oil and other petroleum products.
4. Catalytic desulfurization: This process uses a catalyst to convert sulfur compounds into less harmful substances.
5. Adsorption: This method involves using a solid material to absorb sulfur compounds, such as activated carbon or zeolites.

Desulphurization is important for reducing air pollution and mitigating the negative impacts of burning fossil fuels on human health and the environment. It can also help to reduce greenhouse gas emissions, which contribute to climate change.
