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 resulted from the desorption step to the 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, thus recovering the fugitive organic vapors. According to a preferred embodiment, the compressed vapors resulted from step (b) are at a temperature in the range of between 80 DEG to 150 DEG C., which may be reached by an external heating and the effluent resulted from the desorption step (c) is cooled at a temperature of about 5 DEG C.
