METHODS FOR RECOVERING HYDROGEN FROM ISOMERIZING AND REFORMING OF HYDROCARBONS
摘要
<p>Embodiments of methods for recovering hydrogen from isomerizing and reforming of hydrocarbons are provided. The method comprises the steps of combining a HCl-scrubbed, isomerization-zone net gas stream that comprises hydrogen and C6- hydrocarbons with a reforming-zone net gas stream 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 using a reforming-zone product stream that comprises C5+ hydrocarbons to form a hydrogen-rich net gas stream.</p>
