Dear Sir,

5500 tpd kiln, 5 cyclones SLC pre-heater, pushed to calciner
IDfan power limitation and close to C-string total pressure-drop as well.

We are wondering about Calciner oxygen enrichment.

Maybe something at around 3500Nm3/h of ~80% enriched oxygen air
could bring in some extra clinker capacities.

Any experience with calciner oxygen enrichment, PSA or VSA,
cost, operational and process considerations ?

Thanks, Shavit
