Abstract
Procédé d'échange thermique selon lequel un courant de premier fluide échangeur cède sa chaleur à un courant de second fluide échangeur par l'entremise d'une charge de fluide caloporteur intermédiaire, le taux de remplissage de la charge de fluide caloporteur intermédiaire étant modifié, pour régler la capacité d'echange thermique par amenée ou évacuation de fluide caloporteur. Echangeur thermique permettant la mise en oeuvre du procédé, composé de tubes léchés par le premier fluide échangeur et qui sont environnés par des éléments à fluide caloporteur intermédiaire léchés par le second fluide échangeur, ces éléments pouvant être reliés à un réservoir de fluide caloporteur 7 par l'intermédiaire de vannes d'admission 9 et d'évacuation 10. Application : refroidissement de gaz de craquage d'hydrocarbures.Heat exchange process according to which a stream of first exchanger fluid gives up its heat to a stream of second exchanger fluid by means of an intermediate coolant fluid charge, the filling rate of the intermediate coolant fluid charge being modified, to adjust the heat exchange capacity by supplying or discharging heat transfer fluid. Heat exchanger allowing the implementation of the process, composed of tubes licked by the first exchanger fluid and which are surrounded by elements with intermediate coolant fluid licked by the second exchanger fluid, these elements being able to be connected to a coolant reservoir 7 by the intermediary of inlet 9 and outlet 10 valves. Application: cooling of hydrocarbon cracking gas.
