The hydrogen chloride separation tower in the CDI cannot be liquefied
Thread Content
Let’s discuss why HCL at the top of the absorption tower cannot be liquefied during normal CDI operation How to solve it? Also, how can it be eliminated within the CDI area when HCL is not up to standard?
I’m not sure what process is being used on the friend’s end – to analyze the temperature and pressure of HCL at the top of the distillation tower, as well as some other parameters?
Do we need to liquefy the HCL at the top of the distillation tower? That’s wrong; it’s SiH2CL2 that needs to be liquefied, right?
I’m not sure about your process – is it impossible to condense R22 at -55°C? If HCL fails the test, proceed directly with waste gas leaching
Parsing systems are very simple, and the technology is also quite mature these days
If waste is not a concern, it can be discharged directly into the leaching process; otherwise, it should be held back temporarily until the system is adjusted and the purity meets the requirements
There are two reasons why it cannot be liquefied. 1. The temperature of your refrigerant is not high enough. 2. Your calculation of the partial pressure of hydrogen chloride in the tower exhaust gas is insufficient.
I don’t understand why one hopes that HCl will also liquefy! ! It shouldn’t be necessary! If forced liquefaction is desired, high-pressure cryogenics will do the trick!
Is the purity of HCL important?
Obviously it’s not important, and liquefaction isn’t necessary either
Let’s talk about the daily operating parameters, such as pressure and temperature inside the tower It could be caused by an insufficient amount of refrigerant in your system
