CPP: Recycle LPG from stabilization column to inlet separator

[eastorca]

Dear all,

In a center production processing, I wonder why LPG gas comes out top of Stabilization column shall be compressed and then recycle to Inlet separator? Could anyone give me an explanation. Thank you so much.

I'm trying to understand your facility better;
Is LPG one of the products of the facility, or is it only producing gas + stabilized gasoline?
Is LPG being sent together with the recycle gas to the inlet receiver so it continues to a downstream LPG recovery process unit, e.g.: turboexpander plant?

Perhaps, the recycle lines are for process stable operation or for heavy components recovery.
