Greetings.
This is my first post.
I work in a Linde double column air sepration unit.
I just want to know what is GAP PRESSURE in a expansion turbine?r
Why and how it is genrated?
What could cause it to change(increase or decrease)?
And lastly is their a good book like Ludwig for designing air sepration expansion turbine?

Thanks and Regards.

Siddharthbk:

The best and most efficient way to answer your questions is to identify the fabricator of the expansion turbine that is linked to your air separation plant. If you don’t have their detailed operations and maintenance manual (which would be a bad situation), then contact them and ask the specific questions. If this deals with a reputable fabricator (perhaps Linde), then you will have your correct answers.

I seriously doubt you have the capability – or capital – to invest in mechanically designing as complex and specific a machine as a cryogenic turbo expander. One doesn’t do this and expect the first products to work as expected. It takes money and a lot of time to accomplish the successful product. Perhaps you mean to say that you want to know the inner workings and details of a cryogenic expansion turbine. If that is the case, then the fabricator should also be a good source for this information.

There are a lot of fabricators of Linde-type air separation plants – including the originator, Linde. Some have developed their own cryogenic expansion turbine, while others go to outside sources for this special type of equipment. Is your plant a virtual Linde company product? If so, then you should have no problem with obtaining help on this subject.

Greetings again.
Admin I use Linde expansion turbine.
Its a linde double column plant.
As you said I dont intend to fabricate or design the turbine.
I just want to know working of expansion turbine and characteristics of turbine as are for centrifugal compressor.
