Unique Application of an Epoxy Repair Gel to Eliminate Draft Tube Surface Wear and Cavitation, potentially Improving Turbine Power Generation Efficiency

Product Number: 41216-976-SG

Author: Norm Klapper

Publication Date: 2016

$20.00

A unique project was completed in Mid-2014 at the Powerhouse #3, Turbine Unit #23 refurbishment, Grand Coulee Dam, located in Washington State. The project scope includes a complete overhaul of the turbine bearings, windings, and critical components. As part of the overall scope, the contractor was charged with the task of coating the entire draft tube surface with an epoxy gel. The Bureau of Reclamation, based in Denver, Colorado, had conducted a site survey which indicated severe wear lines, which result in cavitation and the accompanying backpressure on the exiting water outflow to the Columbia River.

The BNY Mellon faced the considerable challenge of repainting the exterior of the 54-story, metal sided One Mellon Center located in Pittsburgh, Pennsylvania. Located in the heart of the downtown, traditional methods of surface preparation and coating application were not viable options. BNY Mellon took the unusual approach of designing the entire project, from the means and methods, to equipment & staging versus the more traditional process of letting a painting contractor design the work sequence and approach.

The application of corrosion inhibitors are fundamental to the safe and reliable operation of carbon steel infrastructure, presenting one of the most cost effective methods of internal pipeline corrosion control when deployed correctly. Despite decades of application in the oil and gas industry, a number of gaps remain in relation to our fundamental understanding of the performance of inhibitors. This is particularly true in the context of partitioning, and more so when the system under consideration comprises multiple surfactants. Part 1 of this two-part paper provides a detailed insight into the fundamentals of surfactant partitioning. Initially, the role of micellization in influencing single surfactant partitioning/distribution behavior between oil and brine is discussed, providing theoretical explanations for single surfactant system responses. The complexity of the systems examined increases with consideration extending to multi-surfactant environments, accompanied by discussion of idealized theoretical behavior. Subsequently, an idealized model to predict multi-component distribution responses between oil and brine is presented. To explore the model’s capabilities, experimental partitioning and micellization data collected from previous studies for two benzyl ammonium chloride corrosion inhibitors (BAC-C12 and BAC-C16) is integrated into the model. Such integration permits investigation into the effect of surfactant concentrations, relative surfactant molar ratios and water cut on partitioning/distribution behavior.

Unravelling Surfactant Partitioning: Part 2 - Experimental Study of Multi-Component Surfactant Partitioning Responses and Their Influence on Inhibition Performance

In Part 1 of this two-part paper, a predictive model for multi-component partitioning was developed based on knowledge of individual component micellization and partitioning characteristics. In Part 2, the model’s validity is assessed through comparison with experimental partitioning data for an 1 wt.% NaCl brine:toluene system containing mixtures of two benzylammonium chloride corrosion inhibitors (BAC-C12 and BAC-C16). Following model validation, the implications of the experimental partitioning behavior on corrosion inhibition performance are examined via rotating cylinder electrode (RCE) experiments. Through selected experiments, the important role of each of the two surfactants and their relative molar concentration in influencing overall corrosion inhibition performance is examined. While BAC-C12 exhibited poor inhibition in isolation, when combined with BAC-C16 at specific molar ratios, BAC-C12 played a crucial role in retaining the longer chain surfactant in the aqueous phase. This response enabled BAC-C16 (the more effective surfactant corrosion inhibitor) to work synergistically with BAC-C12 to suppress carbon steel corrosion more effectively than the two components alone under these particular conditions.

Large scale offshore wind farms are being planned globally and there is a general trend that the size of wind farms, with the installed wind turbines in each farm is becoming greater in number. High build-high solid protective coating is a robust solution to offshore structures splash zone anti-corrosive protection. The importance of coating thickness building-up during application is vital to secure the long-term protection. Furthermore, to have an efficient manufacturing process, application and curing speed is also becoming critical. In this regard, unsaturated polyester coating with outstanding application and turn-over efficiency delivers extra value to both customer and applicator, where the cost of coating, time, and application resources are extremely important. In this work, curing kinetics of unsaturated polyester coating is studied using Fourier transform infrared spectroscopy and Rheometer to evaluate consuming rate of reaction and the cross-linking. Dynamic Mechanical Analysis is utilized to study the glass transition temperature, also to align the storage modulus and hardness development in dry film. In doing so, we have carried out both microscopic and macroscopic mechanical analysis to eventually explain how and why unsaturated polyester coating delivers unique value to faster manufacturing for offshore windmill monopile industry. Knowledge gained in this study is beneficial for the fast-growing offshore wind and sustainability.
