Abstract
The distribution of fluid flowing through a packed bed reactor is determined by placing a plurality of fiber optic sensors at desired locations within the packed bed reactor. A light analyzable tracer component is injected into the fluid flowing through the reactor. Light is supplied to each of the sensors causing any tracer component in the vicinity of the sensor to emit electromagnetic radiation. The emitted electromagnetic radiation is detected at each fiber optic sensor, thereby permitting the amount of tracer in the vicinity of each sensor to be determined, and consequently providing a measure of the distribution of fluid flowing through the reactor.
