Chlorine compressor intercooler corrosion
Thread Content
This post was last edited by yuchenchf on 2011-10-3 11:45. The intercooler of our company's chlorine compressor started to leak after only one year of use. Is there any effective measure to prevent corrosion of the intercooler?
In the past, many domestic manufacturers of liquid ring chlorine compressors experienced corrosion. As far as I know, some manufacturers also had major accidents. The corrosion was mostly due to poor acid concentration control. In addition, some manufacturers also had problems with their cooling water, causing corrosion.
1. In addition, nitrogen replacement protection should be used for the intercooler in standby state.； 2. Use coating anti-corrosion in the water path of intercooling ； 3. Strictly control the working temperature of the intercooler ； 4. The intercooler adopts pressureless water return technology ； 5. Use acid mist traps with high mist removal efficiency ； 6. Replace regularly. This post was last edited by yzhms on 2007-12-9 14:09 ]
I think the main problem is to strictly control the water content in chlorine. If the water content in chlorine is high and exceeds the requirements of the unit or the outlet pressure of the unit exceeds the rated value, corrosion will inevitably occur in the intercooler.
Reply on the corrosion problem of chlorine compressor cooler: 1. Choose a manufacturer with better production technology: Jinhua Machinery, Changfei ； 2. The technical agreement for purchasing the cooler must reflect the pressure test of a single tube. ； 3. You must order about half of the running quantity of spare parts, just in case. ； 4. Strengthen online supervision of circulating water quality. Cooler leakage must not be caused by problems with the circulating water itself. ； 5. Strengthen the combination of online detection and mobile detection of the water content in chlorine to ensure that the water content index is qualified. During each maintenance, the corrosion of the chlorine gas pipeline can be observed to prove the amount of water or acid mud, and corresponding treatment measures should be taken according to the actual situation. ； 6. Strengthen the control of sulfuric acid concentration in the chlorine drying system. The sulfuric acid concentration before entering the acid mist trap of the chlorine compressor shall not be less than 80%. ；

It can be antiseptic and can be used for a long time.
The turbine intercooler needs to use a pressureless return water configuration, so try to use the water pipe route solution.
Why is it water-based anti-corrosion instead of chlorine channel anti-corrosion?
