A hydrocarbon isomerization system for an iC4 feed stream that provides for removal of C3s from an isomerization reactor feed stream by the addition of a depropanizer column to remove C3s from the reactor effluent stream after it has passed through a stabilizer column. This configuration prevents a buildup of C3s in the system and provides significant savings by reducing the size of the chloride treaters that are used to remove chlorides from off gas, increasing chlorides recovered to the hydrocarbon feed stream for use in combination with the isomerization catalyst. Significant utility savings are provided as well as a reduction in the amount of perchloroethane (PERC) and adsorbent that are required.
