Abstract
Abstract A liquid is contacted with an adsorption agent so that the latter adsorbs and retains the impurities in the liquid. Subsequently, a portion of the purified liquid is vaporized. The vapor is brought into contact with the adsorption agent and removes the adsorbed impurities therefrom to thereby regenerate the adsorption agent. After condensation of the vapor so as to segregate the impurities removed from the adsorption agent, the resulting liquid may again be contacted with the adsorption agent.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
186 words
An arrangement for the adsorptive purification of fluids and for the regeneration of the adsorption medium, comprising an adsorption agent; means for contacting a fluid which is convertible between a liquid and a gaseous state with said adsorption agent while said fluid is in one of said states so as to permit impurities from said fluid to be adsorbed and retained by said adsorption agent; and means for converting a portion of the purified fluid from said one state to the other of said states, said converting means and said adsorption agent being in communication during adsorption and conversion thereby permitting said portion of said purified fluid to flow from said adsorption agent to said converting means during the adsorption of impurities from said fluid for conversion of said portion of said purified fluid, and permitting said portion of said purified fluid to flow from said converting means to said adsorption agent subsequent to said conversion for the removal of adsorbed impurities from and regeneration of said adsorption agent by said portion of said purified fluid, wherein said adsorption agent is accommodated in said converting means.
