<p>A method of operation of one or more chemical reactors (12), wherein each chemical reactor defines first flow channels (15) for a chemical reaction process in proximity to second flow channels (16) for heat transfer, and each chemical reactor is provided with fluid connections for bringing about flows of respective fluids through the first flow channels and the second flow channels, involves the steps of shutting down the flows of fluids through at least one of the first flow channels and the second flow channels, and then changing the fluid connections, and then reopening the fluid connections. There is no change in the chemical reaction process performed by the reactors. The change to the fluid connections is preferably such as to achieve a flow reversal. This may involve turning the reactor (12) itself around, or changing the arrangement of ducts connected to the reactor. This changes the thermal stress distribution within the reactor, and can consequently increase the reactor's operational lifetime.</p> |
