What causes blockage in the air-cooled water-soluble corrosion inhibitor of the naphtha gas stripping tower after hydrogenation?
The gas after hydrogenation generally contains some hydrogen sulfide and ammonia. If ammonium chloride is formed, under-crust corrosion can occur, leading to blockages. It might be advisable to improve the water used as a corrosion inhibitor or to strictly control the pH level, and to observe the situation.
This is therefore ammonium salt scaling; corrosion inhibitors are not relevant to this issue. The ammonium salt scale inhibitors produced by our company can effectively prevent ammonium salt scaling.
Simply add a washing line to carry out flushing intermittently.
