Dear All,
As all are giving information about the causes of pluggging in sulfur rundown lines.In my view,
A.sulfur run down lines should be jacketed steam.One more serious thing,should not run Reactor very long on fuel gas or NG during shutdown.It may create later on coking problum in seal legs.because it is very difficult to maintain stoichiometric ratio fuel : Air during shutdown
B.it should be 5% slope to flow sulfur (rundown line) reach to sulfur pit.
