Abstract
Method and system for removal of heavy metal ions from a rich hydrate inhibitor stream, wherein the method comprises a) adding a selective heavy metal reactant to the rich hydrate inhibitor stream, forming a fluid stream comprising heavy metal salt particles, b) separating the obtained fluid stream in three streams a hydrocarbon stream, a recovered rich hydrate inhibitor stream, and a slurry comprising the heavy metal salt particles, c) separating remaining hydrate inhibitor from the slurry thereby obtaining a concentrated rest comprising the heavy metal salt particles.
