Abstract

1. A method of determining the feed of oxygen into a reactor which is filled with a intimately-mixed fluid medium, characterized in that, when the reactor is in operation, alternately the oxygen content of the fluid medium and the change in oxygen content of a circulating part of the fluid medium are measured.
