A process for recovery of thermal energy from contaminated vapor while simultaneously separating volatile organic substances is described, in which the vapor is introduced into a heat exchanger and a heat-absorbing medium is introduced into the heat exchanger, and a heat-absorbed medium is withdrawn therefrom. The vapor is introduced into the lower part of the heat exchanger, and a gas phase enriched with said substances is withdrawn from the top of the heat exchanger, and the condensate poor in said substances is withdrawn from the bottom of the heat exchanger. A device for carrying out the process is described, including a heat exchanger, an inlet for the contaminated vapor, a condensate outlet and an outlet for the volatile substances. The inlet for the contaminated vapor is arranged in the lower part of the heat exchanger, and the outlet for the condensate is arranged at the bottom of the heat exchanger.
