Unique chemistry is developed which allows conservation of water through increased cycles. This chemistry permits control of calcium carbonate up to and exceeding 300 times saturation. This paper will discuss the superior corrosion inhibition properties under these conditions and the properties that afford good protection. Corrosion inhibition studies using weight loss, electrochemical tests and surface analysis show that PAPEMP allows a very effective invisible cathodic barrier to form which incorporates calcium carbonate. The significant property of the inhibitor that differentiates performance and allows it to work under these conditions is its extreme calcium tolerance.
