Petroleum National Geographic Society

Petroleum National Geographic Society

There are huge quantities of petroleum found under Earth's surface and in tar pits that bubble to the surface. Petroleum even exists far below the deepest wells that are developed to extract it. However, petroleum, like coal and natural gas, is a nonrenewable source of energy.

Coal miners are exposed to toxic dust and face the dangers of caveins and explosions at work. When coal is burned, it releases many toxic gases and pollutants into the atmosphere. Mining for coal can also cause the ground to cave in and create underground fires that burn for decades at a time. Petroleum. Petroleum is a liquid fossil fuel.

Thus Flexicoking is an integrated coking and gasification process for upgrading heavy feedstocks. This process converts these feeds to a 99% yield of fuel gas, naphtha, middle distillates, heavy gas oil, and a lowsulfur coke gas. The remaining 1% is petroleum coke containing metals and other ash components present in the feed.

How Fossil Fuels are Used to Generate Electricity

How Fossil Fuels are Used to Generate Electricity

The process in the case of a coalfired generating station begins when the coal is brought into the station on a conveyor belt after stored in large coal piles just outside the station. The conveyor feeds the coal into large pulverizers that crush the coal into a fine powder, thereby increasing the surface area and allowing it to burn more quickly.
