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.

A gas separation membrane module includes a seal between a higher pressure gas and a lower pressure gas. The seal includes a compressible sealing member in between sealing surfaces. At least one of the sealing surfaces has corrosion-resistant cladding provided over either low alloy steel or high alloy steel. The cladding reduce the possibility of a seal failure due to corrosion of low alloy or high alloy steel exposed to acid gases or condensed moisture containing acid gases dissolved therein while at the same not requiring that all surfaces of the membrane module exposed to acid gases be provided with cladding.

An enrichment apparatus and process for enriching a hydrogen sulfide concentration in an acid gas stream to create a hydrogen sulfide rich stream for feed to a Claus. The enrichment apparatus comprises a hydrocarbon selective separation unit operable to separate the acid gas stream into a hydrocarbon rich stream and a purified acid gas stream, wherein the acid gas stream comprises hydrogen sulfide, carbon dioxide, and hydrocarbons, a hydrogen sulfide selective separation unit operable to separate the purified acid gas stream to create the hydrogen sulfide rich stream and a hydrogen sulfide lean stream, the hydrogen sulfide rich stream having a concentration of hydrogen sulfide, and the Claus unit operable to recover sulfur from the carbon dioxide lean stream. The enrichment apparatus can include a carbon dioxide selective separation unit in fluid communication with the hydrogen sulfide selective separation unit, operable to separate the hydrogen sulfide rich stream.

A gas chromatographic method for analyzing natural gas and a natural gas upgrading system using the gas chromatographic method for analyzing natural gas. The method includes transporting the natural gas through a chiller, transporting the natural gas from the chiller to at least two gas upgrading membranes, and operating a gas chromatographic system having at least one upstream gas chromatograph and at least two downstream gas chromatographs. The at least one upstream gas chromatograph, the first downstream gas chromatograph, and the second downstream gas chromatograph all operate simultaneously and utilize the same heating oven to heat samples of natural gas.

A cost-effective solution for the disposal of heavy residue bottoms recovered from a slurry hydrocracking process that include solid heterogeneous catalyst particles is provided by their introduction into a membrane wall gasification reactor in the form of a flowable slurry to produce a synthesis gas and, optionally, subjecting the synthesis gas to a water-gas shift reaction to produce a more hydrogen-rich product stream. Process steam and electricity are produced by recovering the sensible heat values from the hot synthesis gas.

An apparatus and process for reducing vehicle emissions by converting exhaust gases to hydrocarbon fuel. The apparatus and process supplement conventional emission control techniques to further reduce vehicle emissions of harmful substances. The apparatus includes a heat exchanger to extract thermal energy from exhaust gases of a combustion engine that powers propulsion of a vehicle, a membrane separator to separate water and carbon dioxide from the exhaust gases, and a catalytic reactor comprising a nano catalyst. The catalytic reactor receives the water and the carbon dioxide from the membrane separator, contains a reaction of the water and the carbon dioxide that produces hydrocarbon fuel and is facilitated by the nano catalyst, and uses the thermal energy from the heat exchanger to stimulate the reaction. The catalytic reactor is contained within a body of the heat exchanger to facilitate the transfer of thermal energy.

A Performance Grade sulfur-extended asphalt binder emulsion is made by combining a viscosifier, an emulsifier, a Performance Grade sulfur-extended asphalt binder, optionally a saponification agent, and a base aqueous solution. During creation of the asphalt emulsion, none of the components or combinations of them exceeds 275&#xb0; F. The Performance Grade sulfur-extended asphalt binder composition is made by combining free or element sulfur, a linear alkane material, optionally a saturated-backbone polymer modifier, optionally a non-aqueous acid, and a base asphalt. The disclosed Performance Graded sulfur-extended asphalt binder and Performance Graded asphalt sulfur-extended asphalt binder emulsion allow operators using these products directly or in combination with aggregates and other materials to mix and blend the compositions, and apply the compositions in the field, at temperatures less than 300&#xb0; F.
