1) use of Na(OH)
2) we first use filtration method to separate dust particles . We then cool the gases to -200°c .The gases are then passed through a mixture of Na(OH) to remove CO2 gas. Oxygen liquifies at -183 while Nitrogen at -196. The mixture is passed in a fractionating column. Liquid Nitrogen boil first and rises to the top of the solution and is piped off for storage while oxygen settles at the bottom
