PROCESS FOR MANAGING SULFUR ON CATALYST IN A LIGHT PARAFFIN DEHYDROGENATION PROCESS

A process is presented for the management of sulfur on a catalyst. The catalyst is a dehydrogenation catalyst, and sulfur accumulates during the dehydrogenation process. Sulfur compounds are stripped from the spent catalyst and the catalyst is cooled before the regeneration process. The process incl...

Beschreibung
Zusammenfassung:	A process is presented for the management of sulfur on a catalyst. The catalyst is a dehydrogenation catalyst, and sulfur accumulates during the dehydrogenation process. Sulfur compounds are stripped from the spent catalyst and the catalyst is cooled before the regeneration process. The process includes controlling the amount of sulfur that needs to be removed from the catalyst before regeneration. L'invention concerne un processus de gestion du soufre sur un catalyseur. Le catalyseur est un catalyseur de déshydrogénation, et du soufre s'accumule pendant le processus de déshydrogénation. Les composés soufrés sont extraits du catalyseur usé et le catalyseur est refroidi avant le processus de régénération. Le procédé comprend le contrôle de la quantité de soufre qui doit être retirée du catalyseur avant la régénération.
