A process and system for separating and saturating benzene from a reforming reactor effluent begins with introducing the reforming reactor effluent to a combined stabilizer and naphtha splitter. An overhead stream comprising light ends, a sidecut stream comprising C4-C5 compounds, a bottoms stream comprising C7+ compounds and a heart cut stream comprising C4, C5, C6 compounds including benzene are all removed from the combined stabilizer and naphtha splitter. The heart cut stream is introduced to a side stripper to produce a side stripper overhead stream reduced in benzene and a side stripper bottoms stream enriched in benzene. At least a portion of the side stripper bottoms stream enriched in benzene is introduced into a hydrogenation zone to saturate benzene and generate a hydrogenation zone effluent reduced in benzene. The side stripper overhead stream may be recycled to the combined stabilizer and naphtha splitter.
