investment cost air separation unit

[SebFrie]

Can someone give me a rough estimation fot the investment costs of cryogenic air separation plant. Mass specific value (US$/kg air) would be helpfull. Demanded oxygen purity is about 97 per cent molar and the air mass flowrate is about 40 000 tons per day.

The plant will produce Argon if yes is it pure or crude
and the Nitrogen will be produce too?
There is many aspects to the cost depend on the manufacturer design so many plants now adays produce plants with low power consumption in your quistion 40000 ton per day may be only Lide has to this capacity design ?

In this case only the purity of oxygen is of any interest. The purity of Nitrogen doesn`t matter. The unpurities in the Oxygen fraction is due to Argon. Argon itself is not separated. Both, Oxygen and Nitrogen are received in gaseous form, e.g. is expected to be quite small.

you may want to contact air products, air liquide, praxair, etc. They will know better than most, if not try cryotrader.com and a used plant dealer will be glad to help.
