A processing apparatus equipped with a catalyst-supporting honeycomb structure, which is characterized in that corrugated plate-like glass fiber papers having a functional catalyst supported thereon and flat plate-like glass fiber papers having the same functional catalyst supported thereon are alternately laminated without being bonded to each other, to form a catalyst-supporting honeycomb structure, and this catalyst-supporting honeycomb structure is packed in a casing.

A process for altering the composition of a feed gas containing H.sub.2S equivalents is disclosed. The process comprises (a) contacting the feed gas with a solid adsorbent at a temperature of 250-500 C., to obtain a loaded adsorbent, (b) purging the loaded adsorbent with a purge gas comprising steam, thus producing a product stream which typically contains substantially equal levels of CO.sub.2 and H.sub.2S.

The adsorbent comprises alumina and one or more alkali metals, such as potassium oxides, hydroxide or the like.

A temperature swing adsorption apparatuses and process is disclosed comprising passing a feed stream to a first adsorption bed to adsorb one or more contaminants from the feed stream to produce a product stream. A regeneration gas separator overhead stream is passed to a second adsorption bed to provide a second adsorption bed effluent stream. The second adsorption bed effluent stream is passed to a heater to generate a hot regeneration effluent stream. The hot regeneration effluent stream is passed to a third adsorption bed to regenerate the third adsorption bed and provide a regeneration effluent stream. At least a portion of the regeneration effluent stream is passed to a guard bed to remove sulfur and oxygen compounds to provide a treated regeneration effluent stream. The treated regeneration effluent stream is passed to a regeneration gas separator to provide the regeneration gas separator overhead stream.

A method for cleaning an off-gas from viscose production, essentially containing H.sub.2S and CS.sub.2, comprises passing the gas through a catalytic reactor containing a direct oxidation type catalyst, such as V.sub.2O.sub.3 on silica, to convert H.sub.2S in the gas to elemental sulfur, SO.sub.2 or mixtures thereof, either via the oxygen present in the gas or via oxygen added to the gas stream. Elemental sulfur and SO.sub.2 are removed from the effluent gas from the catalytic reactor, and the unconverted CS.sub.2 is recycled to the viscose production process.

Disclosed is a method of adding a feed medium into a bioprocess. The method includes receiving a stream of CO2-rich gas; treating the stream of CO2-rich gas to remove impurities therefrom; preparing an aqueous mixture for absorbing carbon dioxide, the aqueous mixture having at least one inorganic nitrogen compound in a range of 0.1-50 wt % of the aqueous mixture, the at least one inorganic nitrogen compound is a nitrogen source for microorganisms; absorbing carbon dioxide from the stream of CO2-rich gas into the aqueous mixture, the aqueous mixture with absorbed carbon dioxide forming a feed medium; and adding the feed medium into a bioprocess.

A power generation system includes a hydrogen sulfide separator, a hydrocarbon fractionator, a hydrogen sulfide processor, a methane processor, and a hydrogen power generator. The hydrogen sulfide separator separates a gaseous flowback stream into a stream including hydrogen sulfide and a stream including hydrocarbons. The hydrocarbon fractionator fractionates hydrocarbons into methane, ethane and natural gas. The hydrogen sulfide processor converts hydrogen sulfide into hydrogen and sulfur, and the methane processor converts methane into hydrogen and carbon. The hydrogen power generator reacts hydrogen with oxygen to generate electricity. A method for generating electricity from a gaseous flowback includes separating a gaseous flowback stream into a stream including hydrogen sulfide and a stream including hydrocarbons, fractionating hydrocarbons into methane, ethane and natural gas, converting hydrogen sulfide into hydrogen and sulfur, converting methane into hydrogen and carbon, and reacting hydrogen with oxygen to generate electricity.

A composition and method for reducing odors and cleaning packing media and other components in a wet air scrubber using nonionic surfactants, amphoteric surfactants, and a source of humic acid. Preferred nonionic surfactants include regular and low foam nonionic surfactants. The source of humic acid is preferably organic peat humus. The treatment composition is added to water in the wet scrubber at a concentration of 50-1000 ppm. The treatment composition is a premixed composition in a single container, making it unnecessary to separately add ingredients to the water. The treatment composition is effective at reducing odors by at least 50% compared to no treatment. The treatment composition is also effective at significantly reducing foam levels, making it unnecessary to add a separate defoamer to the water being treated. The treatment composition does not need to use defoamers, enzymes, oxidizers, chlorine compounds, or strong acids to be effective.
