Effects of too high flow rate in the liquefied gas stream
Thread Content
Why is it said that an excessive flow rate of liquefied gas when it is delivered can cause rapid vaporization of the liquefied gas inside the tank, leading to a swift cooling of the storage tank? If the storage tank itself has a vapor equilibrium line, isn’t this problem eliminated?
An excessive flow rate of liquefied gas being delivered can cause the pressure in the gas phase space inside the tank to drop too rapidly, resulting in rapid vaporization of the liquefied gas within the tank and a swift cooling of the storage tank. If the storage tank itself has a vapor equilibrium line, the existing vapor space increases, and the rate at which the pressure drop occurs slows down.
Thank you for your guidance; I’ve learned something! ~~~~~~~~~~~
A vapor equilibrium line is generally required for liquefied gas transportation! :)
Under normal circumstances, a certain pressure must be maintained to keep the liquefied gas in a liquid state; if the pressure drops, delivery should be avoided as much as possible, and tank switching should be carried out promptly. This is also a necessary measure to ensure the safety of the storage tank; of course, a vapor equilibrium line is essential.
It’s better to keep production steady; avoid large fluctuations
