02274 EFFECTIVENESS OF CORROSION INHIBITORS IN RETARDING PROPAGATION OF LOCALISED CORROSION

Product Number: 51300-02274-SG

ISBN: 02274 2002 CP

Author: A. Turnbull, D. Coleman, A.J. Griffiths, P.E. Francis, and L. Orkney

Publication Date: 2002

$20.00

In many service applications excursions in solution chemistry, temporary loss of inhibitor, or transient increases in temperature may give rise to localised corrosion. To test the return of inhibition when the loss is remedied, the use of an artificial pit has been investigated using simulations of cooling water and of of oil production formation water.

Evaluation Of Corrosion Pitting In A 317L Stainless Steel Surface Condenser Tube Bundle

Product Number: 51322-17564-SG

Author: Mel J. Esmacher, Edward R. Blessman, Kumar Kembaiyan

Publication Date: 2022

$20.00

The power plant is a natural gas-fired, combined cycle plant with three combustion turbines and a single steam turbine. A large stainless steel surface condenser is used to condense steam off of the turbine, and provide high purity steam condensate return to the boiler system. The steam condenser was put into service approximately 15 years ago. This plant takes makeup water for its open recirculating cooling tower water system from a river location that is inland from an ocean coastal area.

Scale control is vital for cooling water operations, and evaluation of best-fit scale inhibitors for the application is essential, for the scale treatment. One of the traditional test methods for industrial water scale inhibitor screening is static bottle testing. Recently, in other industries, Kinetic Turbidity Test (KTT) has gained more acceptance for scale inhibitor evaluation. KTT uses an Ultraviolet-Visible (UV-Vis) spectrophotometer to monitor scale formation at various dosages of tested products, as function of reaction time. The technology can provide minimum dosage recommendations for the treatment with selected inhibitors, and give the insight on scale formation kinetics and mechanism, under the effects of different types of scale inhibitors.

Polymer dispersancy in waters with particulates such as iron oxide and clay, is also an important characteristic to evaluate, in systems with high levels of suspended solids or fine particles. Previously(currently), this testing was conducted in bottles where the turbidity of solutions were measured by pipette transfer to a cuvette and turbidity meter, providing one data point at a certain time. Kinetic turbidity testing can continuously and simultaneously monitor and record turbidity changes with time, under the effects of various polymer dispersants and dosages. This capability provides more thorough and objective data, for scale control product evaluation.
This paper presents the approach to evaluate scale control chemistries for industrial applications by KTT, and compares the KTT test data, with bottle test results. The laboratory testing results show that KTT provides a fast and data-driven approach for evaluating performance of scale inhibitors and dispersants.
