ABSTRACT:
The invention is concerned with a process for removing mercury from a non-polar organic medium like a liquid hydrocarbon mixture, most preferably a natural gas condensate, by contacting the medium to be treated with a solid adsorbent, preferably an ion-exchange resin, containing active thiol-groups. By this method it is possible to remove mercury from the treated medium in an amount of more than 97%.
