Hysys multiphase flow
Hysys multiphase flow
(OP)
Guys,
How to input multiphase flows (i.e.) oil rate 5000 bbl/d & gas rate 5 mmscf/d in the stream line.
Thanks & Regards,

RE: Hysys multiphase flow
input the flowrate for the oil and specify a molar flowrate on the gas stream till it gives you the desired gas flowrate in MMSCFD.
then, combine the two streams using a mixer. HYSYS will recognize the output flowrate as the reservoir flow rate.
RE: Hysys multiphase flow
You have a specified composition from the reservoir ppl - and a specified flow rate of oil&gas - but the flow rates does not match the calculated flow rates by hysys - you cant get them both to match - if the oil rate matches then the gas rate is off and vise versa.
There are two solutions:
1) Either annonce that you will match the oil rate (or gas rate whatever your preference) and the gas rate will be off
or
2) If gas is less than expected then make a gas stream with a composition that matches the gas phase from a 1 stage split at standard conditions of your reservoir fluid and mix it with the reservoir fluid and use an adjust until you get your desired flow rates - if oil is less then use the oil stream.
Rememeber to raise the issue with the reservoir ppl and inform them of your approach - so that confusion dont arise later on.

RE: Hysys multiphase flow
I have to follow the standards for producing my specifications for the Process Piping.
I was confused, whether,i have to follow,
1.ANSI B31.3 or
2.ASME B31.3
Please clarify my query.
Thanks & Regards,

This belongs in a new tread (and in a different forum. Try to repost in a mechanical engineering forum.
