in amounts greater than 1% is considered sour crude [3]. Sulfurs must be removed from the crude oil before the oil can be refined as sulfurs are damaging to the environment. The higher the sulfur content the less you will pay for the fuel. Hydrodesulfurization removes the sulfur contents. A process in which hot hydrogen rich gas is pumped through the substance and H2S is formed and removed. These purified components of crude oil can then be used as fuel in percentage ratios, like making a cocktail
