Abstract
An autocycle method to control a cooling water system comprising the steps of: PA0 a) adding a treatment product to said cooling water system, with said treatment product comprising inert tracer and tagged treatment polymer in a set proportion; PA0 b) providing a sufficient number of fluorometers, PA0 c) using said sufficient number of fluorometers to measure the fluorescent signal of said inert tracer and the fluorescent signal of said tagged treatment polymer in the water from the cooling water system; PA0 d) using these measured fluorescent signals from step c) to determine the amount of said tagged treatment polymer present in said cooling water system; PA0 e) comparing the amount of said tagged treatment polymer present to the amount of tagged treatment polymer being fed into the system to determine the consumption of said tagged treatment polymer; and PA0 f) using said consumption of said tagged treatment polymer to control the concentration cycles of said cooling water system, with the proviso that said control is implemented by linking any or all of the following parameters PA1 i) the flowrate of the make-up water to the cooling water system; PA1 ii) the flowrate of the tre…
