    Abstract: The present invention is directed to a process for the removal of hydrogen sulfide and sulfur recovery from a H2S-containing gas stream by catalytic direct oxidation and Claus reaction through two or more serially connected catalytic reactors, wherein a specific control of the oxygen supplement is operated. The control and improvement of the process is obtained by complementing, in each major step of the process, the H2S-containing gas stream by a suitable flow of oxygen, namely before the H2S-containing gas stream enters the Claus furnace, in the first reactor of the process and in the last reactor of the process. Especially in application in a SubDewPoint sulfur recovery process the H2S/SO2 ratio is kept constant also during switch-over of the reactors R1 and R by adding the last auxiliary oxygen containing gas directly upstream the last reactor R so that the H2S/SO2 ratio can follow the signal of the ADA within a few seconds.

    Abstract: L'invention concerne un procédé flexible pour la purification d'un solvant inhibiteur de la formation d'hydrates lors du traitement de gaz , en particulier de monoéthylène glycol (MEG), ledit solvant ayant un point d'ébullition supérieur à celui de l'eau et étant ,à un moment au moins, en mélange avec de l'eau et des sels , le procédé opérant différemment avec la même installation selon la teneur en sels du MEG à traiter.
    Le procédé opère selon une phase dite de reclaiming (séparation des sels sous vide suivie de distillation sous vide) lorsque la teneur en sels dépasse le seuil de précipitation et sinon le procédé opère en phase de régénération (absence de séparation de sels et pas de fonctionnement sous vide).
    Avantageusement, le basculement a lieu sous asservissement à un moyen de dosage des sels.

    Abstract: The invention concerns a method for dehydrating a gas contained in water using a hydrophilic liquid dessicant, with regeneration of said liquid dessicant, characterised in that it comprises: (a) a step for absorbing water by contact between said wet gas and a regenerated liquid dessicant derived from step (c), producing a dry gaseous effluent and a liquid dessicant flux loaded with absorbed water and gas; (b) a step for regenerating said water-loaded liquid dessicant in a regeneration zone comprising a re-boiling zone and a distillation zone, the loaded liquid dessicant being sent in said distillation zone, wherefrom comes out, at the top, vapour containing water and from the base in the re-boiling zone, the liquid dessicant still containing water; and (c) a step wherein said liquid dessicant derived from the re-boiling zone of step (b) and still containing water is sent to an absorption zone, wherein the water and the vapour generated by said dessicant is absorbed by a fraction of regenerated or non-regenerated dessicant, taken at one point of the process, and sending said dessicant which has absorbed the water of said vapour towards the re-boiling zone of step (b) and sending the regenerated dessicant to the absorption zone of step (a).
