As per reference books, Differential temperature across Lean TEG to contactor and Wet Gas should be maintained at 5-7 C.
I want to know more on this thumb rule, my queries are:
1.) If delta T is less than 5-7 C How hydrocarbon condensation occurs into lean TEG occurs ?
2.) Natural Gas contains primarily of Methane. Which form of heavier is getting condensed i.e Propane , Butane ???
3.) If delta T is more than 7 C what will be the effect ? Absorption efficiency will decrease ?
