Sulphuric acid production Featured 8 Mar 2005 Print

Sulphuric acid production

Sulphuric acid production. Schematic diagram of the Contact Process to make sulphuric acid from sulphur. Sulphur (yellow) enters a roasting tower on a conveyor belt (far left). The air supply from bottom produces sulphur dioxide (orange), which is piped to the oxidising tower (centre). Catalytic oxidation (450 degrees Celsius and 1-2 atmospheres of pressure) occurs in the presence of vanadium pentoxide (red) to produce sulphur trioxide gas (yellow, more air supplied from bottom). This is then pumped into a tank of concentrated sulphuric acid (green, final stage, right). The sulphur trioxide dissolves in the sulphuric acid to form oleum (fuming sulphuric acid, dark green), which is diluted to form sulphuric acid (bottom right)


Aluminium production Featured 8 Mar 2005 Print

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
