Summary: | A process for the providing a regenerant gas stream for a regenerable adsorbent used to remove water and hydrogen sulfide from a reactor effluent in a catalytic dehydrogenation process is described. The reactor effluent is compressed in a compressor to provide a compressed effluent. The compressed effluent may be treated to remove chlorides, and then passed to a dryer zone having a regenerable adsorbent. A regenerant gas stream is used to desorb the water and hydrogen sulfide and the spent regenerant stream may be passed to a cleaning zone having a sorbent configured to remove hydrogen sulfide from the spent regenerant stream. The cleaned regenerant gas stream may be recycled to the dryer zone to desorb and/or regenerate the regenerable adsorbent. |
