How to use proII to simulate the MEDA regeneration unit?
Thread Content
The documents state that there is an amine process package inside, but I don’t know where to find it since I just installed it. Could someone please tell me the specific steps for simulation? It’s mainly used to address the issue of fluctuating liquid levels in the regeneration tower
This is not something PRO/II can handle
So how should the problem of fluctuating liquid levels in the Dark Night Regeneration Tower be solved?
How can effective data be obtained to analyze the issue of liquid level fluctuations? Thank you
These are system-related issues; what PROII simulates is a state of equilibrium. If calculation is necessary, dynamic simulation might be an option, but the amount of work required for such calculations could be extremely large
I really don’t know much about this. So, how can we determine whether: a) the load on the regeneration tower is sufficient to meet the current demands?； b. Whether crystallization on the tray causes the gas phase to rise through the downcomer, thereby hindering the downward flow of the liquid phase ； c. Whether the heat source for the reboiler meets the heat exchange requirements (we have several sources of 0.3MPa steam; the supply is generally stable, but there are significant instantaneous fluctuations, with variations that occur back and forth along a straight line) ； d. Whether the amine solution is foaming, thereby leading to a decline in the performance of the liquid level tray
Is it the fluctuation in the liquid level of the regenerator tower in the MDEA decarboxylation process? I’ve encountered this issue as well. Mainly, the regeneration load is too high; the rising gas volume is excessive, and once flooding occurs, the fluctuations become very large.
Our main task is desulfurization; the load is indeed high. However, recently, as some units upstream have stopped operating and the load has decreased, fluctuations remain significant, but it won’t rise to 80% or above 90%
