***Preheater sodium salt clogging issue
Thread Content
The *** produced by adiabatic nitration is sent to the hydrogenation reactor after passing through a preheater to produce aniline. At present, this *** heat exchanger often suffers from blockages that lead to increased pressure drops. Those of you who are familiar with the aniline production process – has such a problem occurred to you? What exactly causes the blockages, and are there any effective solutions?
