Zusammenfassung: | EMBODIMENTS OF METHODS FOR RECOVERING HYDROGEN FROM ISOMERIZING AND REFORMING OF HYDROCARBONS ARE PROVIDED. THE METHOD COMPRISES THE STEPS OF COMBINING A HCI-SCRUBBED, ISOMERIZATION-ZONE NET GAS STREAM (58) THAT COMPRISES HYDROGEN AND C6-HYDROCARBONS WITH A REFORMING-ZONE NET GAS STREAM (90) THAT COMPRISES HYDROGEN AND C6- HYDROCARBONS TO FORM A COMBINED NET GAS STREAM THAT COMPRISES HYDROGEN AND LIGHT END HYDROCARBONS. THE LIGHT END HYDROCARBONS ARE EXTRACTED FROM THE COMBINED NET GAS STREAM IN A RE-CONTACTING ZONE (102) USING A REFORMING-ZONE PRODUCT STREAM (88) THAT COMPRISES C5+ HYDROCARBONS TO FORM A HYDROGEN-RICH NET GAS STREAM (116). THE MOST SUITABLE DRAWING IS |
