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.

Disclosed is a catalyst suitable for the catalytic oxidative cracking of a H.sub.2S- containing gas stream. The catalyst comprises at least one or more active metals selected from the group consisting of iron, cobalt, and nickel, supported by a carrier comprising ceria and alumina. The active metal is preferably in the form of its sulphide. Also disclosed is a method for the production of hydrogen from a H.sub.2S-containing gas stream, comprising subjecting the gas stream to catalytic oxidative cracking so as to form H.sub.2 and S.sub.2, using a catalyst in accordance with any one of the composition claims.

The invention relates to a mechanochemical process for decontaminating and/or for eliminating problematic, synthetic, biogenic and biological materials A; for breaking down phosphates B; for immobilising metals and the compounds C thereof; for separating carbon dioxide and carbon monoxide D into elements; and for recovering valuable products E. The process comprises: —providing a material F to be milled containing —at least one material A, B, C and/or D and —at least one type of carbon or carbon-yielding material G, or alternatively providing the components of F and G separately from one another; —filling the material F to be milled into a mechanical mill (1), or alternatively —filling the components of the material F to be milled into a mechanical mill (1) and —milling by means of milling elements (1.2) moved by agitation means (1.4) or by means of rollers (1.4.6); after which —the resulting product I is separated from the milling elements (1.2) or the rollers (1.4.6) and is discharged from the milling chamber (1.1) and worked up. The invention also relates to the use of the products I as valuable materials E, the use of a self-cooling electric motor (4) for driving a mechanochemical mill (1), and mechanochemical mills (1) having new agitation means (1.4).

A method of reducing selenium contamination in a waste water stream is described herein. The method includes channeling a flue gas stream through an absorber, contacting the flue gas stream with an aqueous alkaline-based slurry, such that any selenium byproduct in the flue gas stream forms a selenium compound within the aqueous alkaline-based slurry, controlling oxidation of the selenium compound in the aqueous alkaline-based slurry, and adding a precipitation agent to the aqueous alkaline-based slurry to cause the selenium compound within the aqueous alkaline-based slurry to precipitate.

Dry-scrubbing media compositions, methods of preparation and methods of use are provided. The compositions contain activated alumina and magnesium oxide. Optionally, activated carbon and other impregnates, such as hydroxides of group 1A metals, are included. The compositions exhibit improved efficiency and capacity for the removal of compounds, such as hydrogen sulfide, from an air-stream. The compositions are particularly useful for reducing or preventing the release of toxic gaseous compounds from the areas such as landfills, petroleum storage areas, refineries, drinking water systems, sewage treatment facilities, swimming pools, hospital morgues, animal rooms, and pulp and paper production sites.
