摘要： The invention relates to a process for producing hydrogen, comprising a steam methane reforming (SMR) step for producing synthesis gas, in which heat for the endothermic reaction is at least partially provided by converting electrical energy into heat. The synthesis gas is subject to a water-gas shift step and the shift product is subject to a chemical scrubbing step, to afford a carbon dioxide product stream and a hydrogen raw product stream. The hydrogen raw product stream is further purified by means of a hydrogen production step, which affords pure hydrogen and an off-gas stream. The off-gas stream, rich in carbon monoxide and methane, is recycled to the hydrocarbon containing feedstock stream, so that a combined stream of hydrocarbon containing feedstock, off-gas and steam is supplied to the steam methane reforming (SMR) step.

摘要： The invention relates to a process for producing hydrogen, comprising a steam methane reforming (SMR) step for producing synthesis gas, in which heat for the endothermic reaction is at least partially provided by converting electrical energy into heat. The synthesis gas is subject to a water-gas shift step and the shift product is separated into a hydrogen product and a the tail gas. The latter is subject to a tail gas separation step, producing a hydrogen rich stream, a carbon dioxide product, and an off-gas stream rich in carbon monoxide and methane. The hydrogen rich stream is recycled to the shifted synthesis gas. According to the invention, off-gas obtained in the tail gas separation step is recycled to the hydrocarbon containing feedstock stream, so that a combined stream of hydrocarbon containing feedstock, off-gas and steam is supplied to the steam methane reforming (SMR) step.

摘要： The present invention relates to a process and plant for producing a hydrogen- and carbon oxides-comprising synthesis gas by partial oxidation of a carbonaceous feedstock comprising nitrogen compounds. The invention takes advantage of the different solubility of NH3 and CO2 as the synthesis gas stream is cooled. Water is condensed continuously throughout the cooling of the synthesis gas stream. NH3 preferentially dissolves or condenses into the liquid phase during cooling, but at relatively high temperatures, above about 80 to 100 °C. Further condensation at lower temperatures then preferentially dissolves or condenses CO2 into the liquid phase. Thus, the formation of ammonium salts during cooling of the synthesis gas is prevented.

摘要： L'invention a pour objet un système de purification d'hydrogène une unité de purification catalytique (R100), une unité de sécheur à adsorption, un refroidisseur principal (E101) et une boucle de recirculation comprenant un éjecteur à effet Venturi (V100) configuré pour recevoir en entrée, comme gaz primaire ou moteur, un mélange gazeux provenant de l'unité de purification catalytique (R100) et, comme gaz secondaire, du gaz de régénération ayant circulé dans une colonne (S200, S300) de l'unité de sécheur à adsorption se trouvant dans un mode de régénération, pour délivrer en sortie un mélange du gaz primaire et du gaz secondaire vers le refroidisseur principal (E101).
