A new technology for unloading catalyst from hydrotreating and hydrocracking reactors is being introduced to the Western World. This technology, called the CATnap[trademark] Catalyst Passivation Process, is a chemical process which inhibits the normal oxidative reactions observed with spent catalyst. As a consequence, these catalysts can be unloaded under air, eliminating the very hazardous inert entry commonly practiced today. The inherent benefits of CATnap[trademark] are manyfold: safer operations through eliminating inert entry and suppressing catalyst reactivity; saves time in unit shutdown and catalyst removal; saves cost by reducing turnaround time and associated catalyst unloading expenses; improves catalyst recovery for regeneration and re-use; minimizes hazardous waste and associated costs; provides efficiencies by eliminating the stress of inert entry. CATnap[trademark] promises to set a new standard in catalyst unloading technology.
