Dears, 

 

The overhead of a column is LPG that is subcooled in an air cooled heat exchanger an then it is collected in an accumulator to be pumped back to to the column as a reflux. My question (confusing) is that if the liquid level in the accumulator is X%. what will be in the space above this level. Is it some vapor? Why don't we account for it in our calculation?

 

Regards,

Space above liquid level contains vapor. The nature of the vapor depends on the pressure control system of the column (hot vapor bypass of condensor, inert gas addition, ......whatever).

Hi
The vapor phase should contain at least non-condensables like C1-C1 and also C3-C4.
