Chlorinated benzene exhaust gas absorption problem
Thread Content
Our company's products all use chlorinated benzene as the circulating fluid of the exhaust vacuum pump to absorb the exhaust of each material. Although multiple condensers with large heat exchangers are used for condensation, there is still a strong smell of chlorobenzene at the exhaust outlet. I would like to ask how the exhaust of your products is processed?
This problem cannot be solved by simple cooling, because chlorobenzene has a relatively low flash point and is easy to flash. Therefore, if you want to remove it, you can consider deep cooling the exhaust gas, but the cost will be relatively high.
We used deep cooling, but the effect was average. I wonder if there are other more effective methods?
You can use the exhaust gas biochemical treatment device of Honeywell (China) Co., Ltd. Honeywell (China) Co., Ltd. has branches in Tianjin and Beijing. You can check the contact number online and consult. They have test equipment, and they can also be shipped directly to the production site for testing!
1. Regarding the emission standards of chlorobenzene, it cannot be achieved with cryogenic cooling. Instead, adsorption and tail gas incineration technologies are mostly used. 2. The method upstairs is also good. Can you provide some specific details?
If incineration is used, will the chloride ions in chlorobenzene produce new waste gas? Will dioxins be produced if the temperature is not high enough? If adsorption method is used, what should be done after the adsorbent is saturated? Most of the solid waste sent to the solid waste treatment unit is incinerated, which returns to the above problem.
Carbon fiber adsorption + water vapor desorption technology is a mature process for chlorobenzene tail gas recovery
