HYSYS piping model for Wellhead Pipe to test monifold
HYSYS piping model for Wellhead Pipe to test monifold
(OP)
Hi,
I would like to get some advise in modelling the Hyraulic HYSYS model to determine the velocity of a fluid through the pipes.
I am creating the piping model from Wellhead pipe to the test monifold so that i can know what is the velocity in pipe and to compare to the maximum allowable velocity of the pipe (to prevent pitting on the pipe wall).
I have built my hydraulic model in HYSYS but, I have got one choke valve upstream of the test manifold. My question is how can i model the choke valve in HYSYS and get the velocity through the valve (I believe the velocity at downstream of the valve should be higher than the upstream of the choke valve)?
and how can I model the manifold in HYSYS as it gathered streamline from many sources?
If some has done this before, could you please give me some ideas of this HYSYS model?
Thank you and kind regards,

RE: HYSYS piping model for Wellhead Pipe to test monifold
Since its a stead state model you will have the _same_ mass flow upstream and downstream of the valve. Your velocity will be higher due to the expansion of the gas. The model will calculate this.
HYSYS is not ideal for distributed systems but just add a lot of tees and pipe segments and you will get the results - if this level of details is required!

I can simulate the choke valve with the valve's CV and monifolds using the tees. So far my model gave good calculation on the piping configuration.
Thanks,
