Confusions regarding ASPEN simulations of batch operations such as intermediate tanks

Regarding the issue of simulating batch operations such as intermediate tanks in ASPEN, the problem is that there are always some storage tanks or intermediate tanks in the process that do not operate continuously. For example, a tank has an inlet flow rate of 50, and after some time, a pump with a capacity of 10 m3 is used for discharge. How can such tanks or intermediate buffer tanks be modeled in ASPEN to represent this discontinuous behavior? It’s difficult to maintain mass conservation in such cases; please share your opinions! !

1. Disconnect the process and simulate both ends. 2. Dynamic simulation. 3. Use a separator to simulate the tank outlet flow rate.

Could you explain in detail the third method? Using a component separator?
