Abstract
Abstract An installation for the treatment of fluid having a receptacle (1) defining a non-vertical portion of a path for fluid through at least two adjacent masses (A; B; C) of particulate materials, typically different from each other, each mass being in direct contact with its neighbor or neighbors, without the interposition of a separating grid. The installation is particularly useful for the separation or drying of air.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
116 words
An apparatus for treating at least one fluid, in a vertically extending vessel, comprising: a first vertically extending chamber and a second vertically extending chamber, the first and second chambers separated by at least two adjacent vertically extending masses of particulate material through which pass the at least one fluid circulating from the first chamber to the second chamber along a substantially horizontal circulation path, the two adjacent masses being in direct and continuous contact with each other along a contact interface zone, each mass having a horizontal thickness along the circulation path less than 1/4 of its maximum transverse dimension perpendicular to the circulation path, wherein the two adjacent masses comprise exposed upper end surfaces.
Claim 2
Independent Claim
116 words
An apparatus for treating at least one fluid, in a vertically extending vessel, comprising: a first vertically extending chamber and a second vertically extending chamber, the first and second chambers separated by at least two adjacent vertically extending masses of particulate material through which pass the at least one fluid circulating from the first chamber to the second chamber along a substantially horizontal circulation path, the two adjacent masses being in direct and continuous contact with each other along a contact interface zone, each mass having a horizontal thickness along the circulation path less than 1/4 of its maximum transverse dimension perpendicular to the circulation path, wherein the two adjacent masses comprise exposed upper end surfaces.
Claim 3
Dependent Claim
15 words

Claim 11
Independent Claim
117 words
An apparatus for treating at least one fluid, in a vertically extending vessel, comprising: a first vertically extending chamber and a second vertically extending chamber, the first and second chambers separated by at least two adjacent vertically extending masses of particulate material through which pass the at least one fluid circulating from the first chamber to the second chamber along a substantially horizontal circulation path, the two adjacent masses being in direct and continuous contact with each other along a contact interface zone, the two adjacent masses and the contact interface zone having a common vertical symmetry axis, each mass having a horizontal thickness less than 1/4 of its maximum vertical dimension perpendicular to the circulation path.
Claim 12
Independent Claim
117 words
An apparatus for treating at least one fluid, in a vertically extending vessel, comprising: a first vertically extending chamber and a second vertically extending chamber, the first and second chambers separated by at least two adjacent vertically extending masses of particulate material through which pass the at least one fluid circulating from the first chamber to the second chamber along a substantially horizontal circulation path, the two adjacent masses being in direct and continuous contact with each other along a contact interface zone, the two adjacent masses and the contact interface zone having a common vertical symmetry axis, each mass having a horizontal thickness less than 1/4 of its maximum vertical dimension perpendicular to the circulation path.
Claim 13
Dependent Claim
