Embodiment Construction

[0103] figure 1 Example of

[0104] refer to figure 1 , the method of the present invention is carried out in a plurality of reactors, for example, including reactors 101 , 102 , 103 . Each reactor 101-103 contains a fixed bed of an adsorbent for the component of interest, for example, zeolite 13X for the adsorption of carbon dioxide.

[0105] Each reactor carries out multiple steps, namely: first adsorption step (a), second adsorption step (a1), desorption step (b), purging step (b1), conditioning step (c) and condensation step. The reactors are interconnected and in some of the process steps a reactor can exchange one or more gas streams with one or more other reactors. exist figure 1 In , boxes (a), (a1), (b), (b1), (c) represent the reactors 101 , 102, 103 when the process steps are carried out.

[0106] During the first adsorption step (a), the gas to be treated (eg flue gas) is introduced into the reactor, the target component is adsorbed, an off-gas stream is ...

Abstract

A temperature swing adsorption process for removing a target component from a gaseous mixture (111) containing water and at least one side component, said process comprising: (a) at least one adsorption step, providing a target component-loaded adsorbent and at least one waste stream (112) depleted of the target component; (b) a desorption step, comprising heating of the loaded adsorbent to a desorption temperature (Tdes) and providing a first output stream (116) containing the desorbed target component; (c) a conditioning step; (d) at least one target component-releasing releasing step bringing the solid adsorbent to a temperature lower than said desorption temperature (Tdes) and providing at least one second output stream (117) containing an amount of the target component and containingwater; (e) separating water from said second output stream(s) (117) and (f) subjecting the so obtained water-depleted stream(s) to said adsorption step or to at least one of said adsorption steps.

Description

technical field [0001] The present invention relates to a method for separating a target component from a wet gas mixture containing one or more secondary components. In particular, the present invention relates to methods involving temperature swing adsorption of said target component on a solid adsorbent. Background technique [0002] Separation of target components in gaseous mixtures is particularly important in the fields of chemical industry, fuel, food, power production, etc. This is desirable due to environmental concerns and / or the use of such target components as raw materials in industrial processes. [0003] A target component can be separated from a multicomponent gaseous mixture by chemical scrubbing or by selective adsorption on a solid adsorbent, wherein the gaseous mixture is mixed with a compound containing a compound suitable for the selective removal of said target component contact with the liquid solution. The latter has more advantages than the form...
