Title (EN) PROCESSES FOR PRODUCING OLEFINS FROM PARAFFINS
(FR) PROCÉDÉS DE PRODUCTION D'OLÉFINES À PARTIR DE PARAFFINES
Abstract:
(EN) Processes for catalytic dehydrogenation of paraffin stream is disclosed. The process includes passing a first portion of the paraffin-containing feedstream through a select catalytic reactor in a plurality of catalytic reactors. An internal differential pressure is measured in the select catalytic reactor. A second portion of the paraffin-containing feed stream is bypassed around the select catalytic reactor when the measured internal differential pressure is above a predetermined limit of the internal differential pressure. The bypassed second portion is passed to at least one other catalytic reactor in the plurality of reactors located downstream of the select catalytic reactor being bypassed.
(FR) L'invention concerne des procédés de déshydrogénation catalytique de courant de paraffine. Le procédé comprend le passage d'une première partie du courant d'alimentation contenant de la paraffine à travers un réacteur catalytique sélectionné dans une pluralité de réacteurs catalytiques. Une pression différentielle interne est mesurée dans le réacteur catalytique sélectionné. Une seconde partie du courant d'alimentation contenant de la paraffine est contournée autour du réacteur catalytique de sélection lorsque la pression différentielle interne mesurée est supérieure à une limite prédéterminée de la pression différentielle interne. La seconde partie contournée est amenée à être transmise à au moins un autre réacteur catalytique parmi la pluralité de réacteurs situés en aval du réacteur catalytique de sélectionné qui est contourné.
