How to fix a problem where the alkali scrubber tower in an isomerization unit isn’t working? ?
Thread Content
In the n-butane isomerization unit, the pipeline section from the stabilizer tower to the alkali scrubber was not functioning properly; all of that pipeline was removed, and now the pipeline is working fine. I really can’t figure out where the problem lies! ! Please ask an expert to help answer
Could high temperatures cause air resistance? Also, check to see if salt crystallization has occurred
One issue is whether there is blockage inside your valves and equipment, and the other is what was mentioned above: whether there is crystalline buildup at the point where the alkali meets the gas. Crystalline blockages usually occur when the concentration of the alkali solution being absorbed is too high; you can dilute it to resolve this issue
Sodium chloride shouldn’t crystallize that much; with a pressure difference of 10 kilograms on either side, crystallization won’t cause blockages. We suspect that ferric chloride has clogged the exhaust vent. :Q:Q:Q
It has been determined that sodium chloride crystals are blocking the packing layer of the tower.
