HYSYS - separator with entrained gases in liquid stream

HYSYS - separator with entrained gases in liquid stream

HYSYS - separator with entrained gases in liquid stream

(OP)
What's the best way to use HYSYS to simulate a 3 phase separator that doesn't separate completely? Ie in practise there are entrained gases in the liquid hydrocarbon stream leaving the separator. Is it correct that the HYSYS "separator" operation will always separate 100% of vapour at given T & P? If so, my first guess is to build the HYSYS model to recombine some of gas stream back into downstream liquid hydrocarbon stream, so that it will reflect the real situation. Is there a better way?

FYI the fluid entering the separator is emulsion of bitumen + gases + water (from SAGD) at ~ 140 degC and 600 kPag.

RE: HYSYS - separator with entrained gases in liquid stream

HYSYS has an option for carry over/under etc.

This can be a simple methode of specifying % of either FEED or phase going "the wrong way" or correlation based. Check out the "rating" tab on the vessel property box.

Best regards

Morten

Fantastic, thanks Morten
