Separation method?

Question

Before air is fractionally distilled,dirt and other solid mattter have to be removed,CARBON dioxide and water vapour are then removed

suggest how carbon dioxide and water vapour are removed from the air

Answer 1

i suggest to use large area from small plants & ashines to reduce CARBON dioxide and water vapour

Answer 2

Calcium oxide will remove both...simply pass the air through a bed of calcined lime...

CaO + CO2 ---> CaCO3

CaO + H2O ---> Ca(OH)2

The lime is regenerated by heating the bed to a high temp (calcination)...in above eqs, add heat to right hand side and reverse the arrows.
