Scaling problems in HS Orka’s Geothermal Power plants an overview

Product Number: 51319-13475-SG
Author: Geir Thorolfsson
Publication Date: 2019

HS Orka has operated the Svartsengi Geothermal Power Plant since 1976 the Reykjanes geothermal system since 1982 and the 100 MW Reykjanes Power plant since 2006. Scaling problems have been observed in wells and in most parts of the surface equipment. This paper describes the various types of scaling encountered and the different fluid conditions where scaling is formed. The current methods of scaling mitigations will be provided and described how the plant operation can be made reliable in spite of scaling problems.

Selection of Coating Systems for Concrete in the Water & Wastewater Environment

Product Number: 41206-231-SG
Author: Roger Decker
Publication Date: 2006
$20.00

Concrete is inherently durable – nevertheless, deterioration occurs when subjected to weathering or aggressive environments. For many years, coatings have been applied for aesthetic purposes. In the water and wastewater environment concrete is protected primarily for structural purposes. The increasing use of steel reinforced concrete in modern day construction has led to a growing demand for concrete being structurally protected in all types of industry.

Sensitivity of Localized Corrosion of Additively Manufactured Alloy N06210 in Green death solution

Additively manufactured (AM) Nickel Titanium and Cobalt base alloys have been drastically developed for turbine sour gas and medical applications. It was earlier reported that low porosity AM N06210 that is 82 points of pitting resistance equivalent number by selective laser melting method showed corrosion rates in several acidic solutions similar to the ones of wrought N06210 alloys the corrosion rates of AM N06210 became higher with increasing porosity of the specimens and corrosion resistance dependency on building direction is unclear. Present paper reports dependency of pit and crevice corrosion sensitivity of AM N06210 on building direction and porosity in green death solution. Mechanical property of AM N06210 is also reported.

Sensitization Behavior of Alloy C-276 as a Function of Mu Phase Precipitation

Product Number: 51319-13421-SG
Author: Matthew Perricone
Publication Date: 2019

Nickel alloy C-276 is nominally a single-phase corrosion-resistant alloy used in a wide variety of applications particularly in the chemical process industries. Rich in alloying elements like Mo and Cr that promote corrosion resistance the grain boundary precipitation of mu (µ) phase is avoided since it is typically associated with sensitization. Recent work by the present authors to create an atlas of microstructures for this alloy included experimental validation of calculated Time-Temperature-Transformation (TTT) curves as a function of variation in alloying elements within the composition space specified for the alloy. Precipitation of the intermetallic mu (µ) phase was experimentally determined to be the exclusive result of the heat treatment regimens applied to verify the positions and shapes of calculated TTT curves. The present work is an empirical investigation of the sensitization behavior of alloy C-276 as a function of mu precipitation – generating Time-Temperature-Sensitization (TTS) curves that can be directly compared to empirical TTT behavior.

Setting The Bar For Composite Repairs – Now And In The Future

Product Number: 51319-13136-SG
Author: Casey Whalen
Publication Date: 2019
$20.00

As composite repairs continue to be utilized more frequently the knowledge base of the composite manufacturers installers and the end users has continued to increase as well. The information to be discussed looks to address the “best practices” of the industry by briefly examining each major step within the repair process and highlighting key aspects that are often overlooked or not considered important. Intended for both composite repair novices and industry experts this presentation is split into three primary categories – design installation and inspection.The design portion in this presentation discusses key concerns prior to installation and includes topics such as choosing the right material for the scenario and having a sufficient design document. The next major topic of discussion involves the installation process. When something goes awry with a repair the first victim in any witch-hunt tends to be the installer. This focus on the installer will be re-examined throughout the presentation by looking at deficiencies in training methods and supporting installation documents. Lastly key points about the inspection process will be addressed such as what types of defects should be looked for and what constitutes an unacceptable defect?

Several Case Studies of Causes and Effects of Cuprosolvency

Product Number: 51319-12992-SG
Author: James Datesh
Publication Date: 2019
$20.00

This paper explores four cases of cuprosolvency defined as accelerated uniform corrosion of copper plumbing materials. Cuprosolvency goes far beyond blue-tinted water or stained porcelain and often results in severe pipe wall thinning. Its contributory factors differ from those associated with pinhole corrosion and other localized corrosion mechanisms involving copper or its alloys. Multiple water attributes in various and sometimes unexpected combinations were implicated. Modern water treatment practices including operational and design issues introduce avoidable risks for cuprosolvency as discussed in several case studies.Four situations involved very different root causes and impacts: (1) copper pipe wall thinning throughout a university campus due to specific attributes of the municipal water in combination with the university’s operations of hot water recirculating systems; (2) a vacation community’s problem with exceedances of the EPA Action Level for copper in potable water resulting from a transient drop in pH of the source water; (3) periodic cuprosolvency at a large public facility due to a design flaw in their softening system with damaging side effects on galvanized pipe; and (4) newly-imposed copper discharge limits leading a small city’s wastewater plant to look upstream to the city’s industrial and residential users for cuprosolvency effects.
