Summary: | The present invention relates to a device and respective process for distribution of mixed charges comprising a flat tray in the form of a disc drained by a series of drainage tubes located above the surface of fixed beds of catalysts, capable of promoting the homogenisation and distribution of charges by means of said device. Such drainage tubes mounted in said manner have the objective of restricting and reorienting the flow of mixed charges, multiplying the points whereon they fall, principally of the liquid phase, onto said beds of catalysts. For the purpose of doing so said drainage ducts, being segments of tubes, distributed on the entire surface of said tray possess caps affixed at the upper extremity thereof impeding the direct flow of charge onto the bed of catalyst, creating a reservoir of liquid on the tray, subsequently being drained down such device in a more controlled manner.
La présente invention porte sur un dispositif et un processus respectif de distribution de charges hétérogènes comprenant un plateau plat ayant la forme d'un disque drainé par une série de tubes d'évacuation situés au-dessus de la surface de lits catalyseurs fixes, capables de promouvoir l'homogénéisation et la distribution de charges au moyen dudit dispositif. De tels tubes d'évacuation installés de ladite manière ont pour objectif de restreindre et réorienter l'écoulement des charges hétérogènes, en multipliant les points où elles tombent, principalement de la phase liquide, sur lesdits lits catalyseurs. À cette fin, lesdits conduits d'évacuation, étant des segments de tubes, distribués sur la surface entière dudit plateau possèdent des capuchons fixés à leur extrémité supérieure empêchant l'écoulement direct de la charge sur le lit catalyseur, créant un réservoir de liquide sur le plateau, étant subséquemment drainé d'un tel dispositif d'une manière mieux contrôlée. |
