A method for the recovery of fugitive volatile organic vapors which comprises the steps of: (a) compressing said vapors to a pressure of at least 200 kpa; (b) feeding the hot compressed vapors to the desorption step of a Heat-Mass- Exchange (HME) system; (c) cooling the effluent resulting from the desorption step to ambient temperature and separating out the condensed liquid obtained, and (d) feeding the residual cold vapor phase, after the separation of the condensed liquid, to the adsorption step of said HME system, to recover the fugitive organic vapors, wherein the cold expanded volatile organic compound exchanges heat with the cooled effluent from the desorption step of the HME system.
