Abstract of the Invention The consumption rate of at least one additive to an industrial process in an industrial process is determined. The additive is added to at least one upstream process stream that feeds into at least one process zone in which the additive is at least partially consumed, Any additive residual leaves the process zone in at least one downstream process stream. The consumption rate is determined by a method comprising: adding the additive to the process stream or each of the upstream process streams in an additive feed that contains an inert tracer in known proportion to the additive; monitoring the concentration of the inert tracer in the upstream process stream or each of the upstream process streams and in the downstream process stream or each the downstream process streams; determining the concentration of the additive residual in the downstream process stream or in each of the downstream process streams; calculating the rate of additive consumption in the process zone; and optionally making a consumption-responsive additive feed rate adjustment.
