How to simulate the unloading conditions of low-temperature media using HYSYS & PLUS
Thread Content
As the title suggests, I would like to ask everyone how to simulate the unloading process of low-temperature media in HYSYS or PLUS Since the tank itself is a container, during HYSYS steady-state calculations, the Tank module is treated merely as a flash tank, and I find it to be rather cumbersome to work with. The condition of the materials being unloaded has a tremendous impact on the volume of vapor released from storage tanks (BOG). With a slight change in the ship’s parameters, the amount of BOG changes significantly. It also has a significant impact on the selection of BOG. How do people handle it when doing simulations? Thank you!
This should be solvable dynamically, I guess. But I haven’t learned it yet. Ah, I’ll try harder
I think a steady state can also be estimated roughly, but based on the simulation results, the setting of the ship’s state parameters is crucial.
Get some equipment; these days everything is intelligent and fully automated
This problem is quite difficult to solve; I still haven’t fully understood it yet
LNG unloading conditions: very large LNG storage tanks, around minus 160 degrees? Use a BOG compressor for circulation? Dynamic simulation is good, but even it cannot simulate the possible rolling of LNG tanks. . .
Can ships and tanks be combined for dynamic simulation? Have you done any dynamic simulations of this type before?
Yes, including the logic for the unloading arm. There are also combustion immersion evaporators.
Could you please provide some guidance? Thank you!
It’s okay, let’s discuss it together. If you have any questions, just leave me a message.
