Process for producing hydrogen
A process for the production of hydrogen comprising the steps of: hydrodesulphurisation 203, addition of steam 204, reforming in an autothermal reformer 207, one or more water-gas shift stages 210, condensed water separation, carbon dioxide separation 212, and hydrogen purification 215. The hydrogen...

| Abstract | A process for the production of hydrogen comprising the steps of: hydrodesulphurisation 203, addition of steam 204, reforming in an autothermal reformer 207, one or more water-gas shift stages 210, condensed water separation, carbon dioxide separation 212, and hydrogen purification 215. The hydrogen purification step 215 produces a hydrocarbon containing off gas stream 217 which is split; a portion is used as a fuel gas stream 218 which is fed to one or more fired heaters used to heat one or more process streams within the process, the remainder 219 is compressed and split into a hydrodesulphurisation recycle stream 220 which is used in the hydrodesulfurization unit, and a process recycle stream 221 which is returned to the process. A chemical plant is configured to carry out the process. The process is intended to result in a higher yield of hydrogen per unit of hydrocarbon feed. |
