Are the vapor-liquid separation tank and the steam flash tank just different names for the same thing? Do they have the same working principle?
In a flash tank, there is definitely a large amount of liquid phase and little gas phase. Gas-liquid separation tanks often have a large gas phase volume and a small liquid phase volume.
It’s different; vapor-liquid separation is simply a two-phase separation process, whereas flashing involves the liquid entering the system turning into a gas phase due to pressure changes, thereby enabling vapor-liquid separation. The main difference lies in flashing
The feed to the flash tank is high-pressure saturated condensate, which, after flashing, becomes steam at a lower pressure along with condensate; this is used for steam recovery. The feed to the vapor-liquid separation tank is steam, and it is used to separate and recover a small amount of condensate.
