IN-SITU CATALYST SULFIDING, PASSIVATING AND COKING SYSTEMS AND METHODS

摘要

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.

1. A system for in situ treatment of a metal catalyst, comprising:
a mobile sulfiding module comprising
a module inlet and outlet,a sulfur-containing product measurement device,a sulfur product pressurization device having a variably controllable output,a nitrogen-containing product pressurization device having a variably controllable output,a controller in electrical communication with at least the measurement device and the sulfur and nitrogen pressurization devices, anda first communication device configured to transmit information between the module and an external site; a mobile detection module comprising
an inlet and outlet,a hydrogen sulfide concentration detection device located between the inlet and outlet,a hydrogen gas concentration detection device located between the inlet and the outlet, anda second communication device configured to transmit information between the hydrogen sulfide detection device and the external site and between the hydrogen gas detection device and the external site; and an ammonia gas detection module having a communication device configured to transmit information between the ammonia detector detection device and the external site.
