A process for reducing free oxygen in a gaseous nitrogen stream includes the steps of (i) reforming a hydrocarbon to generate a gas mixture containing hydrogen and carbon oxides, (ii) mixing the gas mixture with a nitrogen stream containing free oxygen, and (iii) passing the resulting nitrogen gas mixture over a conversion catalyst that converts at least a portion of the free oxygen present in the nitrogen to steam wherein the hydrocarbon reforming step includes oxidation of a hydrocarbon using an oxygen-containing gas.

A process for treating offshore natural gas includes processing the natural gas on an off-shore processing facility by, (i) liquefying and fractionating the natural gas to generate a liquefied natural gas stream and a higher hydrocarbon stream, (ii) vaporizing at least a portion of the higher hydrocarbon stream, (iii) passing the vaporized higher hydrocarbon stream and steam over a steam reforming catalyst to generate a reformed gas mixture comprising methane, steam, carbon oxides and hydrogen, (iv) passing the reformed gas mixture over a methanation catalyst to generate a methane rich gas, and (v) combining the methane-rich gas with the natural gas prior to the liquefaction step.

A method of making a sulphided ion exchange resin from an ion exchange resin containing primary or secondary amino group comprises passing a non-aqueous liquid, e.g. a hydrocarbon, feedstock containing elemental sulphur or organic, or inorganic, di-or poly-sulphides through a bed of an ion exchange resin containing primary or secondary amino groups, and so unsulphided ion exchange resins containing primary or secondary amine groups may be used to remove such elemental sulphur or sulphur compounds from liquid, e.g. hydrocarbon, feedstocks. The sulphided ion exchange resins may be used to remove elemental mercury or organic mercury compounds from liquid, e.g. hydrocarbon, streams.

Sulphided ion exchange resins

The invention is a process for removing mercury compounds from a glycol- or alcohol-containing liquid absorbent stream which contains mercury compounds, especially a glycol stream which has been used in a glycol drying plant for removing water from natural gas streams. The process comprises contacting the mercury-laden liquid absorbent stream with a bed of solid absorbent particles, comprising a sulphided metal, optionally supported on support material, or sulphur supported on carbon.
