A process for removing liquid sulfur from a reaction mixture during a gas treating process, especially a process for removing hydrogen sulfide from a gaseous stream. Sulfur which is formed during the process is removed from a reaction mixture by first concentrating the sulfur in a small portion of the reaction mixture and then heating this portion to a temperature which is sufficient to melt the sulfur. The molten sulfur is removed from the reaction mixture and washed with a suitable solvent to remove any remaining reaction mixture.

L'invention, qui porte sur un procédé permettant d'éliminer du soufre liquide d'un mélange réactionnel durant le traitement d'un gaz, a notamment trait à un procédé d'extraction d'hydrogène sulfuré d'un courant gazeux. Le soufre qui s'est formé durant le processus est retiré d'un mélange réactionnel par le biais d'une première concentration de ce soufre dans une petite partie du mélange réactionnel puis d'un réchauffement de ladite partie à une température suffisante pour le faire fondre. Le soufre fondu est alors retiré du mélange réactionnel et lavé à l'aide d'un solvant approprié pour éliminer tout reliquat de mélange réactionnel.
