Coal miners use two primary methods to remove coal. Surface mining is often used when coal is less than 200 feet underground. In surface mining, large machines remove the topsoil and layers of rock known as overburden to expose coal seams. Mountaintop removal is a form of surface mining where the tops of mountains are removed to access coal seams.

Then, the gas is turned into a liquid that is used as fuel. This is done most often through the FischerTropsch process, which involves chemically refining the syngas to eliminate impurities, including sulfur and nitrogen, and converting it into either gasoline or diesel. This fuel is said to be cleaner than gasoline because it is sulfurfree.

A crude oil refinery is a group of industrial facilities that turns crude oil and other inputs into finished petroleum products. A refinery's capacity refers to the maximum amount of crude oil designed to flow into the distillation unit of a refinery, also known as the crude unit.. The diagram above presents a stylized version of the distillation process.

Naphtha is upgraded to high quality petrol by reforming. Gas oil can be used as diesel fuel or can be converted to petrol by hydrocracking. The heavy residue is converted into residual oil or coke which is used in the manufacture of electrodes, graphite and carbides. This process is the oldest technology and is not used in Australia.

Longwall Miner. Twenty percent to 30 percent of mined coal underground is from longwall mining. This is performed by a mechanical cutter that shears coal off from a panel on the seam. The panel being worked on may be up to 800 feet in width and 7,000 feet in length. Mined coal is deposited onto a conveyor that moves the coal to a collection area.

These two separation processes are very energy intensive and, in 1988, accounted for percent (about quadrillion Btus) of the total distillation energy used by the chemical and petrochemical industries (Humphrey et al., 1991). A less energyintensive method for separating olefins from paraffins would therefore be extremely beneficial.
