Dear Expert,

 

If the TEG dehydration unit operated with lower pressure, what things to be attention ?

 

example the pressure previous 850 psig, and will operate in 621 psig. what happened ?

Check GPSA engineering handbook have a rough estimation. Generally find if it is PSA and TSA( I forgot to be frank. So if PSA what would be the general answer?

We use TEG Dehydration Unit, not PSA and TSA. what happened with setting my TEG ?

The question may not be clear to me, but lowering the pressure of a flowing gas will cause the actual gas volume rate to increase. The higher gas volume flow will have higher pressure drop and will also reduce any excess column capacity.
