Recently we are facing the problem of regeneration vessel top manhole gasket leak after several regeneration cycle. Currently using the 36" Graphite filled metallic gasket. During regeneration vessel under go with high temp N2 from atm. temp to 300 degree centigrade at the rate of ~ 60 d/hr. At 300 degree vessel retain for 4 hours. This is operation requirement twice a month & we observed after 6 to 7 cycles of regeneration leak observed from manhole gasket. We are looking for the Gasket specification which can withstand the this kind of thermal swing.
