Abstract
Abstract Gas feed system for a packed bed in which there is provided a plenum chamber within the packed bed comprised of a plurality of separate members supported by the packing, with gas being introduced into the plenum chamber and fed downwardly through the packing and then upwardly through a distributor to packing above the plenum chamber. A liquid feed system includes a main liquid distributor, auxiliary liquid distributors and associated conduits, all positioned within and supported by the packed bed.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
120 words
A contacting apparatus, comprising: a vessel; a packed bed within the vessel; an inlet pipe connected to the vessel wall for introducing liquid into the packed bed; a main liquid distributor positioned entirely within and supported solely by the packed bed; a main liquid conduit positioned entirely within and supported solely by the packed bed for passing liquid from the inlet pipe to the main liquid distributor; a plurality of auxilliary liquid distributors for distributing liquid into the packed bed positioned entirely within and supported solely by the packed bed; and a plurality of auxilliary liquid conduits positioned entirely within and supported solely by the packed bed for passing liquid from the main liquid distributor to the auxilliary liquid distributors.
Claim 2
Dependent Claim
120 words
A contacting apparatus, comprising: a vessel; a packed bed within the vessel; an inlet pipe connected to the vessel wall for introducing liquid into the packed bed; a main liquid distributor positioned entirely within and supported solely by the packed bed; a main liquid conduit positioned entirely within and supported solely by the packed bed for passing liquid from the inlet pipe to the main liquid distributor; a plurality of auxilliary liquid distributors for distributing liquid into the packed bed positioned entirely within and supported solely by the packed bed; and a plurality of auxilliary liquid conduits positioned entirely within and supported solely by the packed bed for passing liquid from the main liquid distributor to the auxilliary liquid distributors.
Claim 3
Dependent Claim
36 words
The apparatus of claim 1 wherein said main liquid distributor is positioned at an intermediate portion of said packed bed and said auxilliary liquid distributors are positioned radially outwardly from and below said main liquid distributor.
Claim 4
Dependent Claim
65 words
The apparatus of claim 1 wherein the main liquid conduit is supported within and by the packed bed on a plane above the plane on which said main liquid distributor is supported, said auxilliary conduits being supported within and by the bed on the plane below the main distributor and said auxilliary distributors being supported by the bed on a plane below the auxilliary conduits.
Claim 5
Dependent Claim
28 words
The apparatus of claim 1 wherein the main liquid distributor is centrally positioned within the bed and the auxilliary distributors are positioned radially outwardly from the main distributor.
Claim 6
Dependent Claim
85 words
The apparatus of claim 1 and further comprising means defining a gas plenum chamber within the packed bed, packing of said packed bed defining a floor for the plenum chamber, gas feed inlet means for introducing gas into the plenum chamber; and a plurality of gas distributing means supported solely by and within the packed bed in fluid communication with packing above and below said plenum chamber, whereby gas flows through the packing floor thereof and gas distributing means into packing above said plenum chamber.
Claim 7
Dependent Claim
16 words
The apparatus of claim 1 wherein the packing is supported on the bottom of the vessel.
Claim 8
Dependent Claim
113 words
A contacting apparatus, comprising: a vessel; a packed bed within the vessel; means defining a gas plenum chamber within the packed bed, packing of said packed bed defining a floor for the plenum chamber; gas feed inlet means for introducing gas into the plenum chamber; a plurality of gas distributing means supported solely by and within the packed bed, in fluid communication with packing above and below said plenum chamber; and roof means for preventing vapor from flowing from said plenum chamber directly to packing above the plenum chamber whereby gas flows from the plenum chamber through the packing floor thereof and through the gas distributing means into packing above said plenum chamber.
Claim 9
Dependent Claim
113 words
A contacting apparatus, comprising: a vessel; a packed bed within the vessel; means defining a gas plenum chamber within the packed bed, packing of said packed bed defining a floor for the plenum chamber; gas feed inlet means for introducing gas into the plenum chamber; a plurality of gas distributing means supported solely by and within the packed bed, in fluid communication with packing above and below said plenum chamber; and roof means for preventing vapor from flowing from said plenum chamber directly to packing above the plenum chamber whereby gas flows from the plenum chamber through the packing floor thereof and through the gas distributing means into packing above said plenum chamber.
Claim 10
Dependent Claim
33 words
