Successful and reliable operation of high pressure utility installations requires a strict control on chemistry. The ideal, simplest and most cost effective manner of controlling the main chemistry related variables in all sections of the steam water cycle is by employing online equipment designed to measure all the key chemistry related parameters.
The data from instruments may be validated from time to time by laboratory personnel bench top checks and instrument calibrations. The data received from instruments is of critical importance to the engineer and chemist. This information is fundamental for understanding their chemistry and its compliance or non compliance and their remedial response to documented site action levels.
Any chemistry or physical change that has a negative or undesirable influence on the ability of the instruments to deliver meaningful data should be approached with caution and skepticism.
For example, if a chemistry is chosen (FFA + neutralizing/alkalizing amines) that directly impacts and significantly elevates CACE measurements, this action will attract serious consequences regarding control of chemistry related deviations. Should the high pressure utility now experience a condenser leak and the very small ingress of highly corrosive inorganic and organic raw water or sea water contaminants, which would normally accompany a noticeable spike in the CACE measurement, would go unseen. The FFA effected change in CACE would now mask the effect of the condenser leak due to the elevated CACE resulting from application of the FFA chemistry used.
Some FFA organic neutralizing/alkalizing amine mixtures have been shown to affect the sensitivity of some online measurements. The majority of these conventional film forming formulations offer a non selective film formation. This means the film would form on most if not all substrates available in the steam water cycle, excluding Teflon/PTFE.
Online instrumentation and equipment is unaffected by Anodamine dosage. Anodamine has been specifically designed to speficially target virgin metal and heat exchange surfaces, the places where corrosion occurs. Operate without compromising your eyes into the cycle.
