Oct 20, 2013· The Basic Oxygen Furnace The Basic Oxygen Steelmaking Process is the UK''s major method for making steel. Modern furnaces will take a charge of up to 350 tonnes and convert it into steel in less than 40 minutes. Basic Oxygen Steelmaking (BOS) makes steel from Blast Furnace iron and up to 20% of scrap metal.
Oxygen Extraction from Lunar Samples
The basic equation is: FeO + H 2-> Fe + H 2 O This process results in release of the oxygen as water vapor. The vapor must be sepa-rated from the excess hydrogen and other gases and electrolyzed. The resulting oxygen is then condensed to liquid and stored. Experiments using samples of lunar ilmenite, basalt, soil, and volcanic glass have
Aerobic vs. Anaerobic Processes
May 06, 2019· The process cells undergo to make this change is called cellular respiration. Two Types of Cellular Processes . Cellular respiration can be aerobic (meaning "with oxygen") or anaerobic ("without oxygen"). Which route the cells take to create the ATP depends solely on whether or not there is enough oxygen present to undergo aerobic respiration.
