T.I.M.E. Service GmbH

Unregenerated catalysts are prone to exothermic reactions on contact with ambient oxygen, which may occur after the opening of a reactor. In order to prevent uncontrolled reactions and for the purposes of primary explosion protection, the vessel is filled with an inert gas (nitrogen) before it is opened, so that the catalyst can be removed in safety. If, because of the nature of the plant, vacuum removal of the catalyst is necessary, enclosed mobile vacuum units equipped with nitrogen recirculation are used for safety reasons. In collaboration with specialised manufacturers, T.I.M.E. Service has developed vacuum units for pyrophoric catalysts. Safe technology permits working with unregenerated catalysts without danger while, at the same time, handling the contact gently.
