Abstract
Abstract A horizontal multiple-chamber, packed column structure for adsorptive separation process wherein loading and unloading of packing material is facilitated, and efficient, effective contact between the packing material and a fluid passing therethrough is provided by the configuration and placement of a fluid inlet and distributor at one end thereof and fluid collector and fluid outlet at the horizontally opposite end, each chamber also including a plurality of axially extending rods to maintain a relatively uniform packing density of packing material in the chamber.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
221 words
A packed horizontal column for adsorptive separation processes, said column comprising a series of separate chambers arranged substantially in horizontal succession, each of said chambers being horizontally displaced from one another, a plurality of walls separating each said chamber from its neighboring chambers, each of said chambers comprising a bed of packing material supported by a holding device, and each of said chambers having a fluid inlet opening and an inlet distributor at one end thereof, and also having a fluid outlet collector and a fluid outlet opening at the end thereof which is horizontally opposite to said fluid inlet opening, said one end and said opposite end being horizontally displaced from one another therebetween constituting the axis of said chamber, said fluid inlet opening and inlet distributor being symmetrically disposed with respect to said fluid outlet opening and outlet collector about a point on said axis midway between said horizontally opposite ends, each of said chambers further including a group of spaced-apart rods extending substantially horizontally from end to end between said horizontally opposite ends, each of said rods being spaced from the other adjacent rods of the group at a distance of from 0.1 to 1 meter, and the ratio of the cross-sectional area of said fluid inlet to the cross-sectional area of said fluid outlet being about √2:1.
Claim 2
Dependent Claim
221 words
A packed horizontal column for adsorptive separation processes, said column comprising a series of separate chambers arranged substantially in horizontal succession, each of said chambers being horizontally displaced from one another, a plurality of walls separating each said chamber from its neighboring chambers, each of said chambers comprising a bed of packing material supported by a holding device, and each of said chambers having a fluid inlet opening and an inlet distributor at one end thereof, and also having a fluid outlet collector and a fluid outlet opening at the end thereof which is horizontally opposite to said fluid inlet opening, said one end and said opposite end being horizontally displaced from one another therebetween constituting the axis of said chamber, said fluid inlet opening and inlet distributor being symmetrically disposed with respect to said fluid outlet opening and outlet collector about a point on said axis midway between said horizontally opposite ends, each of said chambers further including a group of spaced-apart rods extending substantially horizontally from end to end between said horizontally opposite ends, each of said rods being spaced from the other adjacent rods of the group at a distance of from 0.1 to 1 meter, and the ratio of the cross-sectional area of said fluid inlet to the cross-sectional area of said fluid outlet being about √2:1.
Claim 3
Dependent Claim
27 words
A packed column, as recited in claim 1, wherein each of said chambers includes openings at the top and bottom thereof for loading and unloading packing material.
Claim 4
Dependent Claim
38 words
The horizontal column as claimed in claim 1 which is further characterized in that the cross-sectional areas of the inlet and outlet distributors where fluid passes through are reduced as the liquid flow rate across the areas decreases.
