HI,
Hysys can be used to predict the Hydrate formation temperature of a particular gas composition / fluid composition presuming free water present.
To mitigate this, if it is a great concern, heat trace the stagnat lines to maintain a temperature abouve this point - put a safety margin in -...
Ladies and Gentlemen,
Any advice on this querie would be most welcome. Let me set the scene.
3 x 33 WI (Water Injection) Pumps in parallel with each other, 330m3/hr, discharge pressure 330 bar.
Each Pump has an overboard dump line consisting of a HCV choke valve and Emergency trunion mounted...
See the other post I have made in the other thread.
I hope this helps. You have to make a guess of Cl given the data avaliable. The valve vendor may be able to assist you will accurate values for Cl that they have used. Some just use 30.
Cg is like a Cv value for a gas. It represents a value which is termed the Gas sizing coefficient.
There is a standard given formula to work out Cg given the temperature, Pressure Drop, Cl,(Cg/Cv)(dependant on the type of valve), Pressure in, and you will be able to work out the Expected Gas...
