Abstract:
A process for hydrotreating petroleum fractions wherein a hydrogen-rich gas stream passed through the reaction zone on a once-through basis is obtained by passing a hydrogen-containing feed gas stream through an absorber which removes light paraffins. The gas separated from the reaction zone effluent by partial condensation is passed into a stripper as the stripping media used to remove these same light paraffins from the liquid used in the absorber.
