Abstract :
Has conducted research on the effect of molecular sieve absorption 4? to CO2 and
H2O in the purification of oxygen and nitrogen in the PT. Aneka Gas Industri.
Molecular Sieve 4? is a molecular sieve to adsorb carbon dioxide and water vapor
by high pressure and desorption at lower pressures. The maximum standard levels
of CO2 and H2O levels are at 5.0 ppm, if the levels of CO2 and H2O levels exceed
the maximum standards of purity, it can lead to impaired oxygen and nitrogen.
