Oil refining process Featured 8 Mar 2005 Image

Oil refining process

Oil refining process. Schematic diagram of how oil is refined from the crude state to the finished products. The process depends on breaking down the oil in a process named catalytic cracking (at 500 degrees Celsius). The three main areas here are (left to right): catalyst regeneration; cracking tower; and the fractionating tower. Air (blue) is supplied to regenerate the catalyst. Crude oil (grey) is pumped into the cracking tower. The product ends up in the fractionating tower (right). Different components of the crude oil condense at different temperatures, and hence at different heights. The products (bottom to top) are: bitumen, fuel oil, diesel oil, kerosene, naptha, petrol and gas


Aluminium production Featured 8 Mar 2005 Image

Aluminium production

Aluminium smelting process. Schematic diagram of the production of aluminium metal from aluminium ore (bauxite). The first stage (left) is the Bayer Process to produce alumina (aluminium oxide) from the raw bauxite. Down left from top to bottom: the bauxite is crushed (top); chemically digested in sodium hydroxide (caustic soda, red area); alumina hydrate is precipitated (brown) and then heated to form the pure alumina (yellow). The conveyor belt deposits the alumina in molten cryolite (sodium aluminium fluoride, green, reduces melting point to 1000 degrees Celsius). Electrolysis (right, the Hall-Heroult Process) is used to obtain molten aluminium metal (grey, lower right pipe). The positive and negative electrodes are labelled with electrical symbols
