Abstract
An adsorber for the cleaning of air or natural gas by the removal of water as a first component and carbon dioxide and/or a hydrocarbon as a second component from the gas stream to be treated utilizes two distinct adsorber beds traversed in succession by the gas stream, at least one of these beds being vertically oriented so that the gas stream and the regenerating gas pass horizontally through it.
Claims2
An adsorber for the selective removal of two components from a multicomponent gas stream to be treated comprising:
- an upright housing;
- a first adsorber bed in said housing positioned to be traversed by said gas stream to be treated;
- a second absorber bed in said housing spaced from said first bed and traversed by said gas stream subsequent to its traversal of said first bed;
- fittings on said housing for passing said gas station to be treated and a regenerating gas through said beds;
- and
- means for holding at least one of said beds in an upright axial symmetrical orientation so that said gas stream and said regenerating gas traverse said one of said beds substantially horizontally, said beds being composed respectively of an adsorbent trapping a component which upon regeneration is released at least in part in a liquid form and an adsorbent trapping a component which upon regeneration is released in gaseous form, said one of said beds being said second adsorber bed and said second adsorber bed upon regeneration releasing a respective trapped component in gaseous form, said second adsorber bed being disposed above said first adsorber bed, the other of said beds being a round horizontal bed traversed vertically by said gas stream and said regenerating gas, and centered on an axis of symmetry of said one of said beds.
An adsorber for the selective removal of two components from a multicomponent gas stream to be treated comprising:
- an upright housing;
- a first adsorber bed in said housing positioned to be traversed by said gas stream to be treated;
- a second adsorber bed in said housing spaced from said first bed and traversed by said gas stream subsequent to its traversal of said first bed;
- fittings on said housing for passing said gas stream to be treated and a regenerating gas through said beds;
- and
- means for holding at least one of said beds in an upright orientation so that said gas stream and said generating gas traverse said one of said beds substantially horizontally, said beds being composed respectively of an adsorbent trapping a component which upon regeneration is released at least in part in a liquid form and an adsorbent trapping a component which upon regeneration is released in gaseous form, said one of said beds being said second adsorber bed and said second adsorber bed upon regeneration releasing a respective trapped component in gaseous form, said other of said beds being an upright bed traversed horizontally by said gas stream and said generating gas, both of said beds being cylindrical of annular cross section and axially aligned with one another along a common axis, said beds being separated by a partition, said partition being frustoconical and having a half angle corresponding to the maximum flow angle of the adsorbent of the bed therebelow, said partition defining a gap enabling flow of adsorbent from the upper bed to the lower bed.
