HYSYS simulation of temperature and pressure changes over time in a liquid CO2 tank
Thread Content
There is a liquid carbon dioxide tank with insulation on the outside; I plan to use HYSYS to simulate the changes in temperature and pressure within a certain pressure range, as well as the duration for which these conditions can be maintained. Is this simulation difficult? Is it appropriate to use HYSYS for simulation? Can someone help do this? I’ll pay. Thank you! ! ! ! ! qq: 1222687
Temperature and pressure are related to the saturated vapor pressure. What is the connection between adiabatic conditions and the duration of time?
External insulation refers to the use of insulating material wrapped around the outside of the tank, but it is not completely airtight
I don’t know how to simulate it; it involves factors such as ambient temperature, wind speed, and insulation layer parameters (thickness, thermal conductivity), etc. I’m waiting for someone more experienced to figure it out.
There’s no need to consider this in such complexity; I will provide the thickness of the insulation material and its thermal conductivity, or it’s also possible to assume a constant heat input
Still want to let it cool down? What outcome are you ultimately thinking of?
The curves showing how pressure and temperature change over time are obtained
The simulation itself is not difficult; using HYSYS for it is an appropriate choice. The problem is that if you know how to use HYSYS in dynamic mode, you can carry out the simulation easily. But if you are not familiar with HYSYS, even after performing the simulation you won’t know how to use the results. Therefore, the real challenge lies in making it easy to use.
