Abstract:
A method and apparatus for removing peroxides from an exposed naphtha stream is shown and described. The process includes the catalytic reactive oxygen stripping of peroxides thereby generating hydrocarbons and oxygen. Numerous conventional catalysts may be employed. The catalytic stripping reaction can be carried out at substantially lower temperatures than conventional reboiled oxygen strippers thereby resulting in substantial energy savings. Further, the disclosed reactor vessels are substantially smaller and less expensive to build than conventional oxygen stripper columns The disclosed energy efficient reactive oxygen stripping process and equipment is intended to be utilized upstream of a naphtha hydrotreating unit.
