Author: Lorella Angelini

Publication Date: 2007

$20.00

“Tilt-up" is a state-of-the-art building system in which steel reinforced concrete panels are cast on site and tilted up into their final position. The tilt-up panels are load bearing and also function as cladding elements. With the exceptions of integrally colored concrete, tilt-up concrete panels can look bare and unattractive if a finish is not applied. It is also well known that concrete is not a “perfect” material as it shows porosity and micro-cracks which can lead to deterioration over time.

Assessment of the Hydrogen Induced Stress Cracking Resistance of Precipitation Hardened Nickel-based Alloys using the Slow Strain Rate Tensile Test Method – Influence of Microstructure

Product Number: 51319-13365-SG

Author: Ilaria Salvatori

Publication Date: 2019

$20.00

Within the framework of a Joint Industrial Project sponsored by several petroleum companies the behavior of several Precipitation Hardened (PH) Ni-based alloys with respect to Hydrogen Induced Stress Cracking (HISC) resistance was studied using the Slow Strain Rate Tensile (SSRT) test method conducted under hydrogen charging conditions (applying a constant cathodic current density throughout the test). Among the test materials several industrial heats of UNS N07718 UNS N09945/945X UNS N09925 UNS N07725 were evaluated.A detailed microstructural analysis was performed on each heat at different levels involving SEM-FEG examinations at high magnification on etched samples to reveal the phases present at grain boundaries. Methodologies were developed to quantify the grain boundary coverage (length of precipitates at grain boundary divided by the total grain boundary length) and to study the distribution in size (equivalent diameter surface shape factor) of the grain boundary precipitates and applied to the studied materials.Elemental chemical analysis of the precipitates was also conducted by Energy Dispersive Xray spectrometry. Systematic fracture surface examinations were performed after SSRT tests under hydrogen charging conditions and compared to those obtained after SSRT tests in an inert environment.The performance of the different alloys with respect to HISC resistance is discussed on the basis of the plastic elongation obtained in the SSRT tests under cathodic polarization the microstructural features the cracking mode and the microstructural criteria given in the API 6A CRA standard.

The Development of Novel Laboratory Test Method on Evaluation of Scale Inhibition and Dispersancy for Cooling Water Applications

Product Number: 51320-14491-SG

Author: Haiping Lu, Tim Underwood, Zhenning Gu, Bingbing Gu

Publication Date: 2020

$20.00

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.

Standards Used for ‘Partial’ Coating Removal During Maintenance Painting

Product Number: 41216-944-SG

Author: J. Peter Ault, Eric Shoyer

Publication Date: 2016

$20.00

Common methods of maintenance painting have either involved complete removal of existing paint (e.g., SSPC-SP 10, Near White Blast Cleaning) or highly localized preparation of corroding areas using power or hand tools (e.g., SSPC-SP 2 or SSPC-SP 3). Sometimes projects may be designed to an intermediate level where the intent is to reduce the surface preparation level of effort by allowing “good” coatings to remain. In these cases, abrasive blasting or ultra-high pressure water jetting may be used to prepare the entire surface, but well adhered aged coating is allowed to remain.

Evaluation of Coatings for High-Temperature Process Vessel Applications

Product Number: 51324-20612-SG

Author: Bing Yuan; Muni Ramakrishnan

Publication Date: 2024

$40.00

Offshore process vessels of the oil/gas industry operate at high temperatures and sometimes high pressure. Protective coatings designed for high-temperature vessels need to withstand very high temperatures, e.g., higher than 200°C (392oF). The evaluation and determination of their fitness for use at such high-temperature conditions are challenging. In this paper, we demonstrated the use of multiple analytical methods (DMA, DSC, Dilatometer) in the investigation and characterization of structure stabilities of protective coatings in high temperature environment. We analyzed 3 coating samples by DMA with temperature ramping, thermal cycling experiments and thermal stress test. The results of DMA, combined with that from DSC, Dilatometer and mechanical tests provided us deep understanding of high temperature properties of the 3 coating samples. The study also explained the cause of cracking failures of 2 of the samples at different high temperature conditions. The methodology of this paper provides a good way to guide future development work and failure root cause analysis of protective coatings for high temperature applications.

Effective Sand Management Using Complimentary Non-Intrusive Erosion Monitoring Solutions

Product Number: 51324-20641-SG

Author: Anca Dienes; William Fazackerley

Publication Date: 2024

$40.00

Sand production and erosion pose significant challenges in the oil and gas industry, leading to equipment damage, production loss, and costly repairs. Existing sand control techniques such as well completion, sand screens, sand separation, or predictive models for sand production are not 100% effective. This paper presents a comprehensive approach to sand management utilizing complimentary non-intrusive erosion monitoring solutions. The focus is on the integration of acoustic sensors and ultrasonic thickness sensors to detect and assess sand particles in pipelines and process equipment. The use of acoustic sensors enables the detection and characterization of particles, including sand, through their unique acoustic signatures. These sensors provide real-time data, allowing for proactive monitoring of sand production and erosion. In combination with ultrasonic thickness sensors, which provide accurate measurements of material thickness, a risk and impact calculation can be derived. By analysing the risk value obtained from the acoustic sensor and the impact value obtained from the thickness sensor, an overall assessment of asset health can be determined. To facilitate effective sand management, the proposed solution incorporates the integration of these sensors into a single package, accompanied by specialised software. The software allows for comprehensive data analysis, trending, and future predictions. By utilising this integrated system, operators can gain actionable insights into the condition of their assets, enabling timely intervention and mitigation strategies. The benefits of this approach include enhanced asset integrity, reduced downtime, and improved maintenance planning. Additionally, the ability to monitor sand production and erosion in real-time empowers operators to optimize production rates while ensuring the integrity of their infrastructure. This paper presents a practical and cost-effective solution for effective sand management in the oil and gas industry. By leveraging complimentary non-intrusive erosion monitoring solutions, operators can mitigate risks associated with sand production, extend the operational life of their equipment, and optimize production efficiency.

Tailoring Scale Prediction Models to a Specific Application: Reverse Osmosis

Product Number: 51319-13238-SG

Author: Robert Ferguson

Publication Date: 2019

$20.00

Mineral scale formation is a problem across many industries and in diverse applications and equipment. Each application may have specific characteristics that must be taken into account if a modelling system is to be reasonably accurate. The modelling of cooling water and oil field production chemistry have been studied extensively since the 1970’s and state-of-the-art physical chemistry models devloped to simulate them with acceptable accuracy even under extreme conditions.Open recirculating cooling water predictive models for example must incorporate algorithms to concentrate the water treating the process as an “open” system and address cooling stem specific situations including pH control methods and even the impact of chlorination. pH prediction of the concentrated recirculating water is a key requirement.Oil and gas production chemistry modelling presents another set of unique challenges including the distribution of gasses such carbon dioxide and hydrogen sulfide between phases as a brine transitions from bottom hole conditions to the well head and then flashes at the separator. Such a system must incorporate algorithms to treat the process as a “closed” system and partition the critical gasses between phases with pressure and temperature changes and account for the impact of the sometimes dramatic environmental parameter changes upon pH solubility and physical constants.Membrane systems did not begin to receive the same rigorous treatment as oil and gas production cooling water and applications such as geothermal power production until the 1990’s. Much of the software in use by the industry relies upon simple index calculations on the level of the Langelier Saturation Index and saturation indices based upon total analytical values. The mainstream reverse osmosis application specific software generally used is not up to the rigors of high ionic strength high recovery and water reuse membrane systems. They are definitely not capable of adequately modelling cascade systems. The simple indices used for predicting scale formation and as driving forces for dosage optimization do not simulate high ionic strength activity coefficients and near as well as far effects. The simple models fail to account for speciation and the ion association of even such standard (yet critical) pairs such as CaSO4o aqueous.Scale inhibitor models in these simple models also do not account for inhibitor dissociation and the active form of the molecules. They also tend to lack the sophistication of models used in other applications which necessitate an induction time extension approach. Without adequate speciation models inhibitor solubility can not be adequately taken into account or insoluble forms controlled predictably.They also ignore in many cases application specific challenges such as membrane specific ion rejection pH prediction and control in vented (open) or tight (closed) systems and concentration polarization at the membrane water interfaceThis paper discusses the practical application of advanced physical chemistry techniques commonly employed in cooling water and oil field chemistry to application specific modelling of mineral scale formation and control in membrane systems.The techniques are discussed and applied to:· Predicting scale formation;· Identifying the upper driving force limit for inhibitors and blends;· Developing inhibitor models for minimum effective dosage; and· Developing models for preventing failure due to inhibitor solubility.The methods discussed have been validated in field applications.

Case Study on the Application of Ceramic Coatings to Extend Fired Heater Tube Life and Improving Operational Efficiency with Cost Benefit Analysis

Product Number: 51319-13115-SG

Author: Jayant Nair

Publication Date: 2019

$20.00

The aromatics plant is an important downstream petrochemical unit that produces various aromatic hydrocarbons such as xylenes benzene and toluene which are the basic building blocks for production of polyester and polymers resulting in different consumer goods. The heart of aromatics plant is a licensed high performance Naphtha Reforming unit that operates at low pressure and high temperatures required to promote chemical reactions that improve aromatics production.To achieve the required heat there are 4no. of fired heaters with vertical “inverted U” type coil configuration that raise the feed naphtha temperature to around 545 Deg C. The radiant tubes of the heaters are of 9Cr-1Mo (ASTM A335 Gr P9) metallurgy with a maximum tube wall temperature of 652° C. The tubes are prone to excessive scaling due to high temperature oxidation and scale thickness of upto 2mm was found in the tubes. The problem arising due to scaling affect not only the mechanical integrity of the radiant tubes but also lead to multiple operational constraints.From integrity point of view scale being part of metal it is consuming the metal at a rate of 0.25mm/year. This was evident from the UT survey carried out on the tubes which revealed a minimum thickness of 4.6mm as against original thickness of 6.02mm. Secondly oxide scale being an insulator restricts the heat transfer across the tube and thus preventing to raise process fluid temperatures to the required levels. As a consequence with burners at full load the unit had to be operated at lower capacity by reducing flowrate of the process fluid. Moreover due to severe scaling it was not viable to run the unit continuously without taking a shutdown every quarter to clean off the scales. This resulted in further production and financial loss.Following a detailed root cause analysis it was recommended to apply ceramic coating on the radiant tube and extend it to refractory in the furnace box to improve operational and thermal efficiency while maintainingmetallurgical reliability and stability.The ceramic coating was expected to result in severaloperational benefits by creating a uniform heatingprofile along with reducing the diffusion mechanism of oxidation eliminating insulative (scale and oxide)surface layers that form during high temperature operation. Post coating (applied in March 2017) the unit is capable to run at more than 100% at the same heater load and also assurance of long term integrity of the heater tubes. The payback from the investment was within 6 months of project execution.This case study highlights the observations of the radiant tubes along with the cost benefit analysis achieved by the application of ceramic coatings to extend tube life and improve operational efficiency.Keywords: Naphtha Reforming Ceramic Coating Radiant Tubes Oxidation

Powder coating extrusion requires the engineer’s consideration of the raw material chemistry and how each extruder parameter affects the powder’s behavior during compounding. Prior investigations reviewed how changes in extrusion parameters and conditions can affect the coating’s aesthetics and performance. New details in powder coating extrusion processing conditions and formulation chemistry allow the engineer to achieve specific coating characteristics. This study will be an update on the recent developments of long-term weathering exposure of high-performance powder coating topcoats on metallic substrates. Along with accelerated weathering (ASTM D4587), scanning electron microscopy (SEM-EDX) and electrochemical impedance spectroscopy (EIS) were employed to examine the coating’s appearance and performance. These findings will contribute to refining the industry’s knowledge to distinguish key parameters for outstanding long-term performance for topcoat systems.

High-Pressure SSC Testing of TMCP Large-Diameter Pipeline Steel

Product Number: 51324-20855-SG

Author: Thomas Haase; René Rüter ; Christoph Bosch

Publication Date: 2024

$40.00

In the recent years concerns have been raised on the validity of 1 bar H2S testing to be representative of the full extension of SSC region 3 as currently defined in NACE MR0175 / ISO 15156-2. Within this work SSC four-point bend tests have been performed on base material and weld specimens from TMCP-based large-diameter pipes at exposure conditions in the range of 1-12 bar H2S partial pressure in the presence of different levels of CO2 up to 24 bar. The results are discussed based on microstructure and hardness of the tested pipes. Metallographic evaluation of the specimens to distinguish between SSC, grooves or stress-induced pits has been performed based on a recently published micrographic evaluation criteria chart. For this evaluation method, several examples are presented and discussed to contribute to the collection of data as a basis for damage feature evaluation. The results show that the tested TMCP-based large-diameter pipes are resistant to SSC at partial pressures of H2S above 1 bar, based on material parameters and test conditions. It is recommended to further investigate how the limits of SSC resistance depend on the quantity of CO2 present.
