摘要:
In an improved fiber-film type contactor/separator an enhanced coalescing zone is provided by the presence of a disengagement device connected to a shroud that contains a bundle of high surface area vertical hanging fibers, where the enhanced coalescing zone diverts a portion of an admixture of immiscible liquids to flow radially in a path not parallel to the vertical axis of the hanging fibers whereby the diverted portion of liquids contacts a coalescing surface to cause at least one of the liquids to coalesce into droplets. The immiscible liquids are allowed to settle into separate phase layers and first and second outlets selectively remove the higher density liquid from the lower density liquid.

The present invention is directed to an indirect-fired, stationary tube (10), gas/solids or solids/solids, full ceramic pyroprocessing furnace-reactor (80) that uses heat-resistant conveyors (15) to propel solids through the stationary tube (10).
摘要:
An apparatus and process is described whereby a sour hydrocarbon distillate stream is treated in two oxidation zones within the same reaction vessel to oxidize mercaptans. The initial treatment is in the presence of a fiber bundle and the subsequent treatment over a bed of supported oxidation catalyst.
摘要:
Une solution alcaline contenant des mercaptides est régénerée dans un procédé amélioré dans lequel la solution alcaline à regénérer contenant un catalyseur d'oxydation approprié est mise en contact avec un solvant contenant de l'oxygène et qui n'est pas miscible avec ladite solution alcaline dans une zone de réaction comprenant une pluralité de fibres (B) positionnées longitudinalement dans une conduite (10), de sorte que les deux liquides sont en contact tout en s'écoulant de manière concurrente au travers de ladite zone de réaction pendant que les mercaptides contenus dans la solution alcaline sont oxydés en bisulfures et sont extraits simultanément de la solution alcaline et introduits dans la solution de solvant.
摘要:
A process for the removal of residual sulfur compounds from a liquid caustic stream is disclosed. One embodiment of my invention adsorbs disulfides from a caustic stream using an activated carbon adsorbent while another combines both oxidation and adsorption in single step to remove residual sulfur compounds from a rich caustic stream using metal phthalocyanine supported on a solid adsorbent. This process is especially useful as a polishing step in a caustic regeneration process flow scheme.
摘要:
In a process to treat gaseous components obtained from an in situ recovery of liquid hydrocarbons from a hydrocarbonaceous deposit the mercaptans and hydrogen sulfide are separated from each other using lean oil and the hydrogen sulfide further processed to obtain a sulfur-free fuel gas product. The rich oil obtained after treating the gaseous components can be used as a diluent with the liquid hydrocarbons or processed to remove and convert the mercaptans to disulfide oils.
