Disclosed is a liquid phase adsorption process for removing and concentrating heteroatom compounds in hydrocarbons (HCH), comprising the steps of adsorption, copurging and regeneration. In the adsorption step, a liquid hydrocarbon stream is fed to an adsorber, which adsorbs HCH and returns adsorption effluent. In the copurging step, HCH, which are extracted from the previous regeneration, are applied to the adsorber, displacing copurging effluent. In the regeneration step, a polar solvent is flowed through the adsorber, purging HCH. Most of the HCH are then set aside for being used in the next copurging step while a small amount of the HCH are taken out from the process as HCH product. The present invention is economically advantageous in effectively removing HCH from the hydrocarbon stream and increasing HCH concentrations within HCH product.

L'invention concerne un processus d'adsorption en phase liquide pour éliminer et concentrer des composés à hétératomes dans des hydrocarbures (HCH) comprenant les étapes suivantes: adsorption, co-purge et régénération. Lors de l'adsorption, un courant d'hydrocarbures liquides est amené vers un adsorbeur qui adsorbe les HCH et renvoie l'effluent d'adsorption. Lors de la co-purge, les HCH, extraits de la régénération précédente, sont appliqués à l'adsorbeur, l'effluent de la copurge étant ainsi déplacé. Lors de la régénération, on fait circuler un solvant polaire à travers l'adsorbeur pour purger les HCH, dont la plupart sont ensuite mis de côté pour être utilisés dans l'étape de co-purge suivante. De ce processus, on prélève une petite quantité de HCH comme produit HCH. Le processus est économiquement avantageux car il permet d'éliminer efficacement les HCH des hydrocarbures et d'augmenter leurs concentrations dans le produit HCH.
