A 600 MMSCFD of dry rich gas is mixed with 65 MBD (dry condensate liquid) at 1500 psig and 35C  in one single pipeline to be processed in gas plant. The length of pipeline is 200 km.

 

The proces parameters at the inlet of slug catcher is 960 psig and 46C for summer case.

The slug catcher will be sized for winter case (at 10C) .

 

My question: is the rich gas flow rate (600MMSCFD) will decrease due to the condensation of some heavy components  and the gas volume flow rate from the top of slug catcher will be less than 600MMSCFD.

I  agree that the overall material balance will be the same at steady state conditions.

 

A i right?

If you are indeed an Aramco engineer, then you have access to a good simulator. And OLGA, too. The latter is necessary to evaluate slugging in the pipeline.

Hi ,

You may use HYSYS / UNISIM etc for vapour/liquid flow rate. As Mr.Bobby said, OLGA required for slug volume calculation.

Thank you, Yes, this is what I did and I found a very high slug volume which needs a very large slug catcher.
