Turboexpanders Liquid Vapor 1

[tomato5]

Could you indicate how to manually calculate expander hp for vapor service and liquid service? I think several of you would have done these calculations, but if there is one or more which was verified by actual use, that would be a big help, too

thank you

You need to have some idea about the efficiency of the unit in question if you are trying to predict a HP.

See attached link:

Essentially it is the reverse of calculating gas compression horsepower
