Abstract
A technique for treating a reactor that includes taking a reactor offline; clearing the reactor; cooling the reactor; conducting pyrophoric treatment of the reactor, the pyrophoric treatment of the reactor including: providing a buffer-passivation solution; introducing the buffer-passivation solution into the reactor; providing an oxidizer solution; introducing the oxidizer solution into the reactor; draining the reactor of the buffer-passivation solution and the oxidizer solution; and hydrogen gas purging the reactor; cooling the reactor; purging the reactor; and opening the reactor.
