Regarding compressor simulation
Thread Content
I want to create a simulation of a liquid ring compressor, but I don’t know how to set it up. It seems that Aspen doesn’t have any specific settings regarding liquid rings. How can I simulate this to make it as close as possible to the reality? I hope someone with experience can give me some advice. The main problem now is that the simulated power is low; even a significant temperature rise cannot be simulated. I set the phase to gas-liquid two-phase, but the warning ‘There is liquid below the dew point’ still appears in the control panel; it seems that simulation of a liquid ring compressor isn’t possible, is that correct?
Can a compressor compress liquids? Clarify the concept. A compressor can only compress gases.
What compresses liquid substances is a pump.......
1# onlyforyou: It seems like you’re referring to a simulated liquid ring vacuum pump; the compressor in such simulation software is unlikely to be able to handle gases containing liquid.
LZ, it’s the fluid that you need to compress, right? The compressor COMPR is only capable of compressing gases; it cannot handle liquids. Use a pump instead for compression, PUMP
4# It seems De should be set to a lower value; I really don’t know much about compressors. This should be its model number: 2BK1222-8HY93-Z01. It’s of the liquid ring type; I couldn’t find any information on it. Everyone, please take a look.
4# It seems that De should be set to a lower value; it’s likely a vacuum pump. I used to think that vacuum pumps could only reduce pressure, but it turns out they can also increase it. I’ll give it a try, thank you.
Liquids are incompressible. Gases are also incompressible. To increase the pressure of a liquid, a pump can be used. Yet this does not involve compressing the liquid; it is merely a transfer of energy.
The original poster simulated a liquid ring vacuum pump; a compressor can be used along with FLASH (liquid added), and the temperature is determined by the circulating liquid. In practice, the circulating liquid is cooled.
10# hantt0431 I’ll give it a try.
