Whether it is a single nozzle or four nozzles, the so-called level balance is relative; what matters is maintaining a stable liquid level. This balance is dynamic and constantly changing, influenced by factors such as load size, gas flow rate, as well as changes in pressure and temperature. It cannot be determined simply by looking at the amount of water entering and leaving. If that were the case, then setting all valves to an opening that maintains a relatively stable liquid level would mean there’s nothing left to do But in reality this is not the case. Take the water washing tower as an example: its inlet valves are generally set to automatic control, meaning they adjust the liquid level by opening or closing more or less as needed when there is an imbalance between the inflow and outflow volumes of water.
I don’t quite agree with some of your views. Under normal circumstances, when the system is stable, the valve remains at an opening level at which the liquid level stays relatively constant, which allows stability to be maintained. In reality, the inlet valves are basically fixed, meaning that the amount of water entering remains constant; instead, the liquid level is adjusted by controlling the outlet valve. To maintain the stability of the flash system, automatic control is generally not used.
It must be in equilibrium without water; if it is not, it’s because there is an issue with the calculation method. First, the water entering and leaving the wash tower must be taken into consideration, including the liquid water entrained in the syngas, as well as the water that is released or absorbed due to changes in syngas pressure and temperature
It supports Xu’s version for the 4th floor; haha, newcomers working on material balance calculations often overlook the gas flow. Under normal conditions, the syngas coming from the centrifuge contains a certain amount of moisture. This moisture is further cooled and collected in the wash tower, where it enters the tower in liquid form, thus becoming part of the water source used in that tower. If this moisture is not taken into account, the water balance in the wash tower cannot be maintained; however, by including this moisture, the water balance can be achieved……
I’ve learned it, hehe. Could you tell me what kind of calculations you usually do? ? How are things like thermal balance, mass balance, and material balance calculated? Could you tell me your calculation methods? ? ? Thank you,
