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.

The Development of Steel Preparation Technology

Product Number: 51220-282-SG

Author: Kenneth E. Rossy

Publication Date: 2020

$20.00

The intent of this presentation will be to briefly analyze the evolution of the steel surface preparation market by focusing on three common methods for steel surface preparation used today (i.e., dry abrasive blasting, wet abrasive blasting and ultra-high-pressure blasting (UHP)) and the effects of water and additives on cleanliness, degree of surface preparation, coating integrity and coating adhesion. This presentation will include test results comparing the effects and results of different forms of surface preparation and the resulting coating application characteristics.

The Edgy Truth About Corrosion - How Carbon Nanotubes (CNT’s) are Redefining Edge Protection

Product Number: 51220-251-SG

Author: Joe Davis

Publication Date: 2020

$20.00

This paper will outline the results of using CNTs in liquid applied coatings, resulting in the elimination of secondary surface preparation steps such as grinding, chamfering, and rounding of edges as well as eliminating the need to apply a stripe coat. The overall impact realized from the elimination of these process steps include, increased productivity, increased throughput, improved edge coating performance, and substantial lowering of project costs.

The Effect of CO2 Partial Pressure on the Formation and Protective Characteristics of Iron Carbonate Corrosion Products

This study investigates the effect of carbon dioxide (CO2) partial pressure on the rate of formation and the protective characteristics of iron carbonate (FeCO3) corrosion product layers on X65 carbon steel in aqueous systems. Autoclave corrosion tests were performed at 80 °C in CO2-saturated 3 wt.% sodium chloride solution at partial pressures from 5.5 to 15.5 bar. Linear polarization resistance and electrochemical impedance spectroscopy electrochemical methods were utilized to provide insight into the stages of corrosion product layer development. Analysis of the electrochemical response under each condition revealed key, distinguishable stages associated with the development of an FeCO3 layer as its role transitions from predominantly blocking steel active sites, to ultimately providing additional corrosion suppression through formation of a diffusion barrier. It was found that at higher CO2 partial pressures, the onset of diffusion control was accelerated, but the overall corrosion rate was greater than at lower pressures.

The Effect of Crack Start Positions on NACE TM0177 DCB Elastic Compliance

Product Number: 51319-12842-SG

Author: Jun Nakamura

Publication Date: 2019

$20.00

The Double Cantilever Beam (DCB) test method standardized in ANSI NACE TM0177 is increasingly applied as a quality assurance test to specify the performance of carbon and low alloy steels for sour service. The DCB test method has been modified and specified tightly from the view point of specimen geometry test environment and initial stress intensity factor controlled by arm displacement to obtain highly repeatable test results.NACE TM0177 2016 method D has various types of starter notch configurations on DCB specimens. Crack start position shifted change specimen of EDM notch has been in accordance with NACE TM0177 since 2016 and the distance from a pin hole to a crack starter has been different.Previous research the influence of crack starter position on K1SSC has been revealed using Finite Element Analysis (FEA) and DCB tests. In this paper in order to clarify the applicability of compliance curve in TM0177-2016 and propose the new compliance curves FEA and experimental approach was performed. K1SSC of DCB tests should be evaluated in the same crack start positions from the view point of a fracture mechanics.

The Effect of Different Polyaniline Types in Silicon Dioxide Containing Coatings for Carbon Steel Protection in Artificial Geothermal Brines

Product Number: 51319-13121-SG

Author: Gabriela Aristia

Publication Date: 2019

Carbon steel is non-resistant to uniform and pitting corrosion in geothermal brines and high alloyed materials which exhibit excellent performance are relatively costly. Coating systems become an alternative to protect carbon steel from corrosion in the geothermal environment. In this research a coating system consisting of polyaniline and silicon dioxide was optimized by investigating differently synthesized polyaniline types in the coating regarding their protective effect on carbon steel. SEM images of the phosphoric acid and dodecylbenzenesulfonic acid doped polyaniline showed different morphology which suggested different physical and chemical properties. The geothermal brine found in Indonesia was simulated by an artificial solution with pH 4 containing 1500 mg/l Cl- 20 mg/l SO42- 15 mg/l HCO3- 200 mg/l Ca2+ 250 mg/l K+ and 600 mg/l Na+. Evaluation of the coating system was performed by surface analysis of the exposed specimens and electrochemical tests i.e. electrochemical impedance spectroscopy (EIS) and open circuit potential (OCP) at 150 °C with 1 MPa pressure. Visual assessment of exposed specimens with single component addition into coatings (polyaniline or silicon dioxide) showed that coatings underwent degradation. Therefore a combination of pigments addition was investigated in the tested geothermal brine to observe the improvement of corrosion protection.Key words: geothermal coating polyaniline corrosion

A large part of the remaining natural gas reserves worldwide is sour, i.e. H2S-containing. Many oil and gas fields, especially in North America, Central Asia and the Middle East, are highly sour with an H2S fraction of several percent. Internal corrosion in sour environments is associated with a high risk of severe localized corrosion attacks.

The Effect of Extender Pigments on Corrosion Resistance and Gloss Retention of Topcoats

Product Number: 51324-20969-SG

Author: Donald C. Lawson

Publication Date: 2024

$40.00

This study evaluates the gloss retention and corrosion resistance of different particle sized extender pigments via dispersion with various milling techniques. We examined high speed dispersion, planetary mixing, and media milling. Gloss retention and corrosion resistance were measured after accelerated testing methods that included cyclic salt fog with UV exposure (ASTM D5894) and EIS (electrochemical impedance spectroscopy) over steel and aluminum substrates. The dispersion blends were incorporated in a solvent-borne fluoroethylene vinyl ether (FEVE) resin and evaluated against commercially obtained high performance topcoats
