Abstract

A system and method for efficiently treating metal catalyst resident in a reactor vessel comprises a sulfiding module, a sulfur source, an ammonia source, and/or a coking source, a hydrogen sulfide detection module, a hydrogen gas detection module, a pH detection module, an ammonia gas detection module and a remote computer all arranged and configured to communicate wirelessly and to allow remote control and monitoring of the modules and process so that catalyst may be sulfided, passivated and/or soft-coked in situ.
