    Abstract: A process for production of ammonium thiosulphate (ATS) from H2S, NH3 and SO2, comprising producing ATS in a first absorption step by treating a first stream comprising H2S and NH3 with more than 0.3 mole H2S per mole NH3 with a solution containing ATS and ammonium sulphite, said solution being produced, in a second absorption step, by treating part of the solution from the first absorption step with a second gas stream gas stream comprising SO2. The second gas stream is obtained by combusting the H2S-containing off gas from the first absorption step supplemented with H2S-containing gas imported from other sources and/or by importing SO2-containing off gas streams from other souses. The content of NH3 in the off gas from the second absorber may be decreased by adding the equivalent amount of SO2 to the off gas upstream of an aerosol filter removing the NH3 and SO2 as a solution of NH4HSO3, which is fed to the first or second absorber, while the off gas from the filter is passed to the atmosphere.

    Abstract: Process and plant for hydrotreating a liquid oil feedstock stream comprising the steps of i) conducting the liquid oil feedstock stream to a stabilization step by reacting the liquid oil stream with hydrogen in the presence of a catalyst for producing a stabilized composition, and separating therefrom: a stabilized stream comprising a gas phase, and a stabilized liquid oil stream; ii) providing a main hydrodeoxygenation (HDO) step, comprising: ii)-1 conducting at least a portion of said stabilized stream comprising a gas phase, or a stabilized feed stream combining at least a portion of said stabilized stream comprising a gas phase and a portion of said stabilized liquid oil stream, to a main hydrodeoxygenation (HDO) step in a first bed active in hydrodeoxygenation (HDO), thereby producing a first main hydrotreated effluent stream; ii-2) combining at least a portion of said stabilized liquid oil stream with said first main hydrotreated effl-uent stream, thereby producing a first mixed stabilized gas-liquid oil stream; ii-3) con-ducting said first mixed stabilized gas-liquid oil stream to a subsequent bed active in HDO, thereby producing a main hydrotreated effluent stream.

    Abstract: A plant and process for producing hydrogen, comprising: a primary reforming unit arranged to receive a hydrocarbon feed, such as natural gas, and comprising: a combustion section comprising a catalyst suitably for steam methane reforming, and one or more burners for providing heat for said steam methane reforming, for thereby generating a synthesis gas stream and a flue gas stream, and a convection section comprising heat exchangers for thereby generating a cooled flue gas stream; wherein said one or more burners are arranged to receive a preheated combustion air stream and a preheated fuel gas stream derived from a downstream hydrogen purification unit which is arranged to receive at least a portion of said synthesis gas stream, for thereby generating a hydrogen-rich stream and an off-gas stream; and in which the fuel gas stream is a portion of said hydrogen-rich stream i.e. first fuel gas stream, or a gas stream, i.e. second fuel gas stream, resulting from combining at least a portion of said off-gas stream and a portion of said hydrogen-rich stream. The invention relates also to method of retrofitting an existing plant for producing hydrogen.
