- glycol dehydration 

- chilling system.

 

and what is the advantages and dis advantages of each one  including CAPEX and OPEX

 

appreciate to get help ASAP

How deep of removal do you need? If the gas goes to a processing facility, you will most likely need a TEG unit or a mol sieve. Chilling systems work well for intermediate levels of dehydration. For these levels of gas a chilling system would be a lower CAPEX and OPEX.

In addition to the above

TEG systems are economical at 500 pounds and above.

Chilling systems have potential hydrate - It depends on water dew point spec.
