Unformatted text preview: Design 4: Both LiAgX and AgA zeolites separating them Design 1: LiAgX zeolite Nitrogen Removal – LiAgX removes nitrogen with a 96.42% purity Oxygen and 62.74% recovery. – The is the best zeolite for nitrogen removal Argon Removal – Argon to Oxygen selectivity of 1:1. – Requires a large volume of LiAgX zeolite to accomplish required purity Large volume of zeolite is required. Costs and inlet airflow rate increases. Design 2: AgA zeolite Nitrogen Removal – Nitrogen to Oxygen selectivity of 5 to 1 in AgA zeolite – Selectivity is lower than if using LiAgX zeolite Argon Removal – Argon to Oxygen selectivity of 1.63 to 1 – Best design for Argon removal Large volume of zeolite is required – Costs and inlet airflow rate increases. Design 3: Mixed zeolites Nitrogen Removal – LiAgX has a higher loading and selectivity of nitrogen than A gA . – Not beneficial to mix them in order to rid of the nitrogen. Argon Removal – AgA has a higher loading and selectivity toward argon, selectivity being...
