Piping downstream Expander goes upward to 15m from Expander centerline
Piping downstream Expander goes upward to 15m from Expander centerline
(OP)
Dear all,
In our LPG plant, Process Gas at 95bars , 12°C @ inlet of Expander will have -41°C , 22bars @ the Oultlet of Expander and becoming Mixture Liq & Gas. However; this mixture goes through piping routed upward vertically to 15m from Expander centerline to the Vessel.
In other hand, engineering point of view, we always make slope downward to the Vessels.
Please can anyone explain to me, why the liquid in this configuration will not backflow towards the Expander.
Regards

Thanks to All,
I think the difference of pressure is not a good explanation, since from the outlet of Expander up to Vessel inlet the differential pressure is so low.
However, Can you Mr Latexman be clearer by characterization of the Flow, to understand this matter.

You'll need to research and find a correlation and phase map for your situation.
Good Luck,

Condensation of a liquid phase from gas (or second liquid phase from liquid) by dropping bulk fluid temperature is very fine droplets. Ground fog and clouds in the sky are common examples of mists with drop size way smaller than any liquid condensed on heat transfer surfaces.
