Evaporation tank vacuum level issue
Thread Content
In terms of the process, how can the evaporation tank achieve the specified low pressure or vacuum level? For example, what type of pump should be used, how should the process flow be arranged, and where should the pump be installed?
The steam outlet of the evaporation tank is connected to the condenser, while the material outlet of the condenser is connected to the collection tank (upper head). The vacuum pipeline connects to the vacuum buffer tank at another interface on the upper head of the collection tank, and from there it connects to the vacuum pump. The selection of a vacuum pump should be determined based on the properties of the material and the amount of evaporation
Wow, expert! You helped me out when I was in trouble last time too!
In Aspen, simulated evaporation is achieved using a combination of a heat exchanger and a flash tank, with the pressure of the flash tank being defined directly. Can Aspen, as you mentioned in your process description, control the pressure of the flash tank by using a vacuum pump in order to create a vacuum condition?
It probably won’t work, but if you simplify the model appropriately, I mean, what data do you want to obtain?
I'm talking about vacuum distillation, which is fast. You achieve negative pressure by reducing the volume through condensation in a heat exchanger; it can only serve as a reference.
I just have such a question; I also think it’s not possible! I want to choose the right vacuum system, select a vacuum pump
This estimate should work; the calculation process is outlined in the manual. It seems to be related to factors such as pressure, the volume of equipment and pipes, and the amount of air leakage – you can check those details for more information
Please send me the specific requirements, and we can design a plan for you. 13586097102, Li Xiaoli
The vacuum pressure for flash evaporation or distillation depends on three factors: 1. The capacity of the vacuum pump – its ability to remove gas, its vacuum capability； 2. Condenser thermal load ； 3. Airtightness of the vacuum container ；
