Is it feasible to use a single liquid phase pipe in LNG tankers or storage tanks for both pressurization and unloading?
Thread Content
To simplify the tank truck/tank process, the tank truck has only one liquid phase line and one gas phase line. During liquid discharge, the liquid phase exits the hose and splits into two paths: one path goes to the booster to increase the pressure of the gas phase. The liquid is being unloaded through another route; I’m not sure if this approach is feasible
It should have an impact; in tank trucks, there are three pipes for the liquid phase, the gas phase, and the self-pressurizing liquid phase. In a situation I encountered, air blockage occurred in the self-pressurizing liquid phase, which prevented the tank truck from building pressure. If the liquid phase and this other phase were combined, it would make it difficult to discharge the liquid, unless each of them has its own venting system. The above is for reference only
May I ask how the problem of overpressure in the air resistance was resolved during unloading later on?
Theoretically feasible, but highly difficult to implement; not practical and cannot be realized
