Systems and methods of preventing an event occurrence or mitigating effects of an event occurrence in an industrial facility are disclosed herein. In some embodiments, a first input is received from a first sensor and, based at least in part on the first input, an initial action is automatically generated. In response to the initial action, a second input is received from a second sensor and, based at least in part of the received first and second inputs, a likelihood of an event occurrence is determined. Based at least in part of the determined likelihood, a remedial action configured to prevent the occurrence of the event occurrence is automatically generated. In some embodiments, the remedial action is generated in real-time and can be directed to a process condition, environmental condition, or secondary source.

A system for carbon capture includes an oxy-fuel combustor for combusting a hydrocarbon with pure oxygen to produce heat energy and carbon dioxide, a COS converter for converting the carbon dioxide to COS, a transport means for transporting the COS, a sulphur recovery unit for recovering sulphur from the COS and an adjunct sulphur-burning power plant for combusting the sulphur to generate energy for powering one or more carbon capture and storage processes.

Disclosed herein is a system and method for sulphur-assisted carbon capture and utilization. The system includes a sulphur depolarized electrolyser (SDE) for receiving electricity, H.sub.2O and SO.sub.2 and for electrolysing the H.sub.2O and SO.sub.2 to produce hydrogen and sulphuric acid (H.sub.2SO.sub.4), a decomposition reactor for receiving and decomposing the H.sub.2SO.sub.4 into SO.sub.3 and H.sub.2O, wherein the H.sub.2O is recycled to the SDE, a sulphur submerged combustor for converting the SO.sub.3 to SO.sub.2 and producing S.sub.n vapor, a sulphur power plant for combusting S.sub.n vapor to produce SO.sub.2, electricity and heat and for supplying the SO.sub.2 and the electricity to the SDE and for supplying the heat to the decomposition reactor. The hydrogen is delivered to a carbon capture and utilization facility. An optional Flue Gas Desulphurisation (FGD) regenerable system removes SO.sub.2 from flue gas, a CO.sub.2 converter generates COS, and a separator separates the COS from the flue gas.

Embodiments of the disclosure include systems and processes for the recovery of sulfur dioxide (SO.sub.2) from tail gas of sulfur recovery plant or from flue gas of a power plant, such as flue gas originating from an H.sub.2S-containing fuel gas for a gas turbine. SO.sub.2-containing gas is dissolved in chilled water and produce SO.sub.2-containing chilled water. The SO.sub.2-containing chilled is contacted with H.sub.2S-containing gas to aqueously react H.sub.2S and SO.sub.2 and form elemental sulfur. A water stream with the entrained sulfur is routed to a solid-liquid separate, and separated sulfur may be processed or disposed of. The water is recycled and chilled for use in the reaction. Embodiments also include the generation of sulfur dioxide (SO.sub.2) from produced sulfur instead of using tail gas or flue gas.

A process for substantially removing hydrogen sulfide from an ammonium sulfate solution. The process involves maintaining the pH of the solution to a range that optimally removes entrained hydrogen sulfide. The hydrogen sulfide is then reacted with sulfites, bisulfites, or sulfur dioxide to form ammonium thiosulfate.

A method for recovering sulfur from an acid gas feed is provided. The method comprising the steps of mixing the acid gas feed and an absorption process outlet stream to form a combined Claus feed, introducing the combined Claus feed and a sulfur dioxide enriched air feed to a Claus process to produce a Claus outlet gas stream, introducing the Claus outlet gas stream to a thermal oxidizer, treating the thermal oxidizer outlet stream in a gas treatment unit to produce a dehydrated stream, introducing the dehydrated stream to a membrane sweeping unit to produce a sweep membrane residue stream and a sulfur dioxide enriched air feed, introducing a sweep air stream to a permeate side of the membrane sweeping unit, and introducing the sweep membrane residue stream to a sulfur dioxide absorption process to produce the absorption process outlet stream and a stack feed.

Methods of producing a treated gas by removing nitrogenous compounds are disclosed. Methods of recovering ammonia from a gas stream having nitrogenous compounds are disclosed. Methods of producing a fertilizer product from organic waste are disclosed. The methods may include introducing aqueous sulfurous acid into a gas stream having nitrogenous compounds to absorb the nitrogenous compounds in a liquid and produce a treated gas. The methods may also include maintaining the pH of certain solutions above 5 or introducing an oxidant into certain solutions to produce sulfate ions. Systems for removing nitrogenous compounds including a reaction subsystem, a solids-liquid separator, a temperature control subsystem, an oxidation control subsystem, and a recirculation line are also disclosed. The systems may be employed to remove nitrogenous compounds from a gas stream, recover the ammonia from the gas stream, or produce a fertilizer product from the recovered ammonia.
