Highest Inlet Pressure for an Expander

[RotaryG]

What is the highest inlet pressure for an rotary expander working on air you know of and what were the flow rates?

Perry Chem Engg Handbook 7th edn says 3000psig max inlet pressure on page 29-42. Nothing stated about flows or feed stream chem composition at this feed pressure.
Max stated permissible exit liquid content 50% by weight of total exit stream - this seems rather high.

If you need more info, speak to Mafi Trench, now part of Atlas Copco.
or
Rotoflow, now part of Air Products and Chemicals.

I've see up to 200 bar from standard products.
You could also check with Cryostar or Chart Industries (Purchased LA Turbine recently).

You could probably check with the original owners (Cryogenic Industries/Nikkiso), as a lot of the employees there now are ex-AC!
