There are different methods of dew point control system such as

External Refrigeration

J-T valve and Low Temperature Separator system

Turbo-expander and Low Temperature Separator system

 

Our clients generally prefer propane or freon for external refrigeration. I would appreciate if any one can suggest as to what is the maximum possible hydrocarbon dew point achievable using these refrigerants.

 

 I was reading from the below hyperlink

http://www.ipt.ntnu....ifikasjoner.pdf

 

 At page 17 of the pdf, it suggested that very low hydrocarbon dew point is not achievable on J-T valve arrangement and very low hydrocarbon dew point is achievable when turbo-expander arrangement is used. 

 

Can anyone explain the reason behind the above statement?

Also, if the above statement is true, what is the maximum possible hydrocarbon dew point achievable using J-T valve and Turbo-expander system?
