Abstract: Capturing at least one heavy metal, from mercury and arsenic, contained in a moist gas comprising water vapour, by the following steps: a) heating the moist gas by heat exchange with a compressed heat transfer fluid obtained in step e) in order to obtain a condensed heat transfer fluid and a gas reheated to a temperature Tc; b) bringing the reheated gas into contact with a heavy metal capture mass in order to obtain a gas depleted in heavy metal; c) decompressing the cooled heat transfer fluid; d) cooling the gas depleted in heavy metal by heat exchange with the heat transfer fluid produced in step c) in order to obtain a cooled gas at a temperature Tf, the heat transfer fluid being vaporized; e) compressing the vaporized heat transfer fluid in a manner such as to obtain a compressed heat transfer fluid, the compressed heat transfer fluid being recycled.
