Claims9
A process for shutting down a Fischer Tropsch reactor, the process comprising:
- a) stopping a reactor fresh feed;
- b) opening or increasing flow to a reactor tail gas purge line to maintain adequate flow through the reactor;
- c) allowing pressure within the reactor to drop to a level below that of a sweep gas reservoir;
- d) opening a sweep gas valve to allow flow from the sweep gas reservoir to a reactor inlet;
- e) allowing a sweep of sweep gas through the reactor to substantially remove fresh feed gas;
- and
- f) closing the sweep gas valve and blocking the purge gas line so that flow through the reactor goes to zero.
