Graduation Project Entitled:

Recycling Fly Ash from Burning Heavy Oil in Power Plants in Saudi Arabia

"Recycling of Power Stations Residual Oil Fly Ash"

Supervised by: Dr. Ashraf Tawfiq Bakkar

Prepared by: Eng. Said Muhammad Harb

Heavy oil is used as fuel in many power plants in the Kingdom. The combustion results in large amounts of volatile dust, which is separated from rising fumes and deposited in different ways. Three kilograms of dust result from the combustion of every cubic meter of oil. Huge amounts of dust are buried in desert landfills. This dust contains many heavy elements harmful to the environment, such as cadmium, chromium, and lead. But it also contains precious and rare elements, such as vanadium and nickel in proportions close to those in natural materials.

The project aims to identify the characteristics and composition of this dust, and explore opportunities for vanadium and nickel extraction. This laboratory study is conducted on samples brought from Al-Shuaiba power plant.

Sustainability is an important step for continuous development without any impact on nature, which must be adapted to the economy, industrialization, and urbanization.
