Abstract: A method for treating an acid gas stream in a sulfur recovery system is provided, the method including providing a motive fluid to an ejector, providing the acid gas stream to the ejector to obtain a mixture, the mixture comprising the motive fluid and the acid gas stream, providing the mixture to a reaction furnace, providing a combustion gas to the reaction furnace, the combustion gas comprising oxygen, and reacting the contents of the reaction furnace. An apparatus for treating an acid gas stream is also provided.

Abstract: Processes and systems for degassing liquid sulfur may include mixing a gas, such as air, with a liquid sulfur mixture comprising sulfur, hydrogen sulfide, and hydrogen polysulfides to form a sulfur-gas mixture. The sulfur-gas mixture may then be transported to a separator, storage vessel or storage tank for separating the sulfur-gas mixture.

Abstract: Sulfur emissions from liquid sulfur are reduced, or even entirely avoided by degassing the liquid sulfur at pressure in an out-of-pit vessel and by sweeping the rundown pit (or vessel) with a sweep gas that is non-poisonous for a hydrogenation catalyst. Acid gases from degassing are fed at pressure to the Claus unit, while sweep gases are fed to the tail gas treatment unit to substantially recycle the acid gases to extinction. In preferred plants and methods, motive fluids and booster eductors or compressors are not needed, and incineration of the acid gases can be avoided.

Abstract: Disclosed is a reactor, a structured packing, and a method for increasing the rate of decomposition of polysulfides and oxidation of polysulfides and hydrogen sulfide in liquid sulfur. The reactor, the structured packing, and the method involve a structured packing for contacting a first stream and a second stream in a reactor including a catalyst. The catalyst increases the rate of decomposition of polysulfides and oxidation of polysulfides and hydrogen sulfide in the liquid sulfur of the first stream with the second stream. The first stream includes liquid sulfur containing polysulfides and dissolved hydrogen sulfide. The second stream includes an oxygen-containing gas.

Abstract: A sulfur recovery system for recovering sulfur from a sulfur plant feed stream including a first sulfur removal system and a second sulfur removal system. The system includes a sulfur plant feed inlet to the first sulfur removal system, the sulfur plant feed inlet being capable of providing a sulfur plant feed stream at a first pressure. One or more oxidizing gas inlets are arranged and disposed to combine at least one oxidizing gas stream with the sulfur plant feed stream to form a combustion gas for combustion in the first sulfur removal system at a second pressure. A flow restriction device is operably configured to control an operating pressure in one or both of the first sulfur removal system and the second sulfur removal system. A gas processing plant and method for recovering sulfur from a sulfur plant feed stream are also disclosed.

Abstract: A process is set forth for improving an oxygen-enriched Claus plant by recycling through an ejector effluent from the first condenser back to the reaction furnace to moderate oxygen induced high temperatures and thus allow additional oxygen-enrichment and attendant throughput in the Claus plant.

Abstract: Disclosed is a process for degassing liquid sulfur under pressure. A stream of liquid sulfur containing polysulfides and hydrogen sulfide and a stream of an oxidizing gas are introduced into a vessel and intimately mixed to provide intimate contact between the two streams. The streams are passed through the vessel at a pressure of at least about 40 psig and at a temperature and for a residence time sufficient to remove substantially all of the polysulfides and hydrogen sulfide from the liquid sulfur.
