Device to dry catalyst roaster conveyor belt and method of using same

Abstract

A system and process for removing an inorganic salt from a catalyst roaster belt is disclosed. The system includes an apparatus with a drying vessel having a catalyst roaster belt inlet, a catalyst roaster belt outlet, a heating medium inlet, and a heating medium outlet, wherein the catalyst roaster belt inlet and the catalyst roaster belt outlet are spaced apart along a first direction, the heating medium inlet and the heating medium outlet are spaced apart along a second direction, the heating medium inlet is spaced apart from the catalyst roaster belt inlet in the second direction, and the catalyst roaster belt inlet is between the heating medium inlet and the heating medium outlet along the second direction. The system includes an acid bath and a moveable catalyst roaster belt extending from the acid bath through the catalyst roaster belt inlet and through the catalyst roaster belt outlet. The process includes the steps of providing a catalyst roaster belt with an inorganic salt disposed thereon and supplying a heating medium to a first side of the catalyst roaster belt such that heat from the heating medium flows through the catalyst roaster belt to a second side of the catalyst roaster belt to vaporize the inorganic salt.
