ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to installations for the treatment of at least one fluid, of the type comprising at least one receptacle defining a non-vertical portion of a fluid path through at least two masses of adjacent particulate material disposed in the receptacle.
BACKGROUND OF THE INVENTION
Installations of this type find widespread application in the art, with particulate materials such as catalysts and/or adsorbents. In most of the these uses, obtaining optimal performance depends on the constant thickness of each mass of particulate material in the direction of fluid flow, which is to say the geometric precision of the interface between two adjacent layers. Until now, particularly in installations with masses of concentric different adsorbents, this interfacial precision requires the emplacement, which is delicate and difficult, of an intermediate grid, as described in EP-A-0,118,349.
SUMMARY OF THE INVENTION
The present invention has for its object to provide a simplified installation for the treatment of fluid, with considerably reduced capital costs and offering great flexibility of use and numerous possibilities for optimization.
To do this, according to one characteristic of the invention, the two adjacent masses of particulate material are in direct contact with each other in an interfacial region, typically substantially vertical, substantially flat or preferably substantially cylindrical.
In the present invention, by “direct contact in an interfacial zone”, is intended an interfacial zone without mixing, or with slight mixing for a slight depth, free from any wall or partition interposed between the two adjacent masses.
