A method and apparatus for removal of hydrogen sulfide from a process gas stream is presented where the process gas is contacted in an absorber with a liquid catalyst to remove the hydrogen sulfide and produce a sweetened process gas stream. The liquid catalyst with absorbed hydrogen sulfide as an admixture is sent directly to a separate stand-alone oxidation unit without subjecting the admixture of spent liquid catalyst to a separation process that removes dissolved gas. The admixture is directed directly into a downcomer in tire oxidation unit positioned between a combined oxidation and. flash stage and a deaeration stage, where hydrocarbon gases carried over from the process gas stream are separated and removed from the oxidation unit. Removing a final admixture from the oxidation unit and recirculating a first portion of the final admixture to the absorber and second portion to a sulfur removal unit that is physically located at elevation above the oxidation unit.

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.
A liquid separator system having a gas phase zone, an aqueous phase zone and a denser liquid zone is used to separate mixtures of fluids. The separator can be used for separating molten sulfur from liquid redox solution or reslurry water. The system includes a vessel with a top part and a bottom part. The vessel has a larger diameter at the top part than at the bottom part. The system also includes an inlet for introducing a redox solution or reslurry water and molten sulfur, which is denser than redox solution or reslurry water, into the vessel. An outlet near the bottom part of the vessel allows a flow of the molten sulfur from the vessel. An interface control structure senses an interface level between the redox solution or reslurry water and the molten sulfur, and the interface control structure controls the flow of molten sulfur from the outlet. The interface control structure is adjusted to optimally alter the vertical height of the interface level within the vessel so that the residence time of the molten sulfur in the vessel does not decrease as the sulfur production throughput decreases, and so that the interface area of the molten sulfur and the redox solution is reduced as the sulfur throughput decreases. A pressure controller monitors the pressure in the vessel and adds or removes gas from a gas phase zone in the vessel to maintain a predetermined pressure regardless of the vertical height of the interface.

Single vertical tower for treating a stream of rich caustic containing mercaptan compounds
A separation process for separating two or more immiscible liquids using contactors utilizing high surface area vertical hanging fibers is disclosed. This separation process is especially useful in the separation of disulfide oil formed during the oxidation of spent caustic solution that was used to remove sulfur contaminates from light hydrocarbons.
An improved process for reduction-oxidation desulphurization uses an oxidizer operating at a pressure greater than the absorber where a liquid reduction-oxidation catalyst solution contacts a sulfur-containing gas feed stream.
A one-step process for desulfurizing an oxidized sulfone-containing fuel stream, such as a diesel stream, is disclosed where mass transfer and conversion of sulfone occurs simultaneously such that the sulfur atom in sulfone molecule is removed as sulfite to provide a low-sulfur diesel stream. The diesel stream for treatment is obtained as a result of the oxidation of a thiophene-rich diesel stream with an oxidant to provide a sulfone-containing diesel stream. The one-step process uses a single vessel having a shroud of vertical hanging fibers to affect the mass transfer of sulfones in diesel into contacting with an aqueous solution of alkali metal hydroxide where it is converted to sulfite and biphenyls. The sulfite-rich aqueous solution and low sulfur diesel are then separately removed from the vessel.
In a catalytic treatment process, mercaptans in sour hydrocarbon are oxidized to disulfide oils using an aqueous treatment solution containing a chelated polyvalent metal catalyst, alkali metal hydroxide, and the alkali metal salt of at least one alcohol in a non-dispersive mixing apparatus wherein an upgraded hydrocarbon containing the disulfide oils is produced.

Flow control method and apparatus for a continuous multiple zone mass transfer
An apparatus and method of contacting a liquid with different gases sequentially in separate mass transfer zones within a single vessel, the mass transfer zones operatively in fluid communication with each other, including intimately contacting the liquid with a process gas in co-current flow in a downstream mass transfer zone to effect mass transfer between the liquid and the process gas, and introducing the liquid into an upstream mass transfer zone with a second gas, different from the process gas, thereby effecting mass transfer between the liquid and the second gas. The rate of flow of the liquid from the upstream mass transfer zone to downstream mass transfer zone is controlled by the controlled addition of a third gas into one or more downcomers separating each mass transfer zone such that the specific density of the liquid in the downcomers provides a driving force that controls flow.
