Underground natural gas storage (UGS) is an important component of the overall natural gas transportation and distribution system. It enables the utilities to supply natural gas during high seasonal demand periods and store gas during periods of lower demand. There are approximately 627 underground gas storage sites worldwide with a working gas capacity of 319.³ Billion m3 ( about 11.8 Trillion Cubic feet). The U.S. has a total of 414 natural gas storage fields, out of which 25 are inactive.

Metallic corrosion is a natural inevitable phenomenon defined commonly as the deterioration of metals due to reactions with their environments. The global cost of corrosion estimated by NACE in 2013 was found to be $2.5 trillion (USD), which is approximately 3.4% of the global gross domestic product (GDP). The two-year global study released at the CORROSION 2016 conference in Vancouver, B.C., Canada, assessed the economics of corrosion and the role of corrosion management in establishing best practices for the different industrial sectors. It found that implementing corrosion prevention best practices could result in global annual savings of 15-35 % of the cost of damage, which is equivalent to $375-875 billion (USD). These estimations excluded the cost of individual safety and environmental consequences from corrosion. Corrosion mitigation has been extensively researched. The methods of corrosion prevention include, but are not limited to, selection of the right material of construction, coatings, corrosion inhibitors, and cathodic protection.^1,2

During operation, due to offshore production environment exposure, the sealing barrier of the flexible pipes can be damaged because of polymer chains degradation. There is great interest in understanding the influence of pressure, temperature, fluid composition, and supercritical CO2 on degradation of flexible pipes sealing barrier materials. Therefore, it is extremely relevant a qualitative study of deleterious effects of each one of the factors mentioned above.

Real Time Sour Water Corrosion Prediction for Fluid Catalytic Cracking Overhead System

Product Number: 51323-18785-SG

Crude feed often contains contaminants / heavy amounts of sulfur compounds that may degrade equipment or even the finished product. These sulfur and nitrogen compounds react with hydrogen to form hydrogen sulfide (H2S) and ammonia (NH3) within certain units and can lead to formation of ammonium bisulfide salts (NH4HS) when cooled. NH4HS salts may lead to plugging, and if wet, rapid under deposit corrosion can occur. Hence, water washing ahead of NH4HS salt formation is essential to prevent wet salt corrosion and ensure safe unit operations.

Recent Advances In Depth Assessment Of Stress Corrosion Cracking Using Tangential Eddy Current Array On Carbon Steel Pipelines

Product Number: 51322-17983-SG

Author: Michael Sirois, Mathieu Bouchard

Publication Date: 2022

Stress corrosion cracking (SCC) is a failure mechanism that occurs in susceptible materials exposed to a corrosive environment and submitted to tensile stress above a certain threshold. In the presence of these combined factors, SCC can occur and potentially lead to the failure of an asset. This failure mechanism has been widely reported in several susceptible alloys of carbon steel, making SCC a considerable threat for pipelines in contact with corrosive soil.

Recent Advances On The Influence Of Microstructural Characteristics On Corrosion Resistance In H2SO4 Of Anodized Titanium

Product Number: 51322-17589-SG

Publication Date: 2022

$20.00

Industrial usage of Plasma Electrolytic Oxidation (PEO) has grown consistently in recent years, thanks to the improved characteristics imparted to the oxide film in terms of surface adhesion, hardness, crystallinity, uniformity, and corrosion resistance. The metallic substrate is not subjected to elevated temperature and the overall equipment complexity is relatively simple, making the technique a good candidate for surface functionalization. In PEO treatments, high voltages are employed (~ 150-750 V 1) allowing for the formation of an insulating, or at least semiconductive, oxide layer that’s limits ion transport responsible for the initial coating growth. Beyond the spark voltage (prerequisite the enter the PEO regime) oxidation does not occur only as the result of a continuous flow of ions but rather it takes place after the cooling of a plasma discharge.

Recent Failures Of Accelerated High Temperature Sulfidation Corrosion In The Oil Refining Industry

Product Number: 51321-16738-SG

High temperature sulfidation is one of the oldest damage mechanisms in the refining process such as crude distillation unit, vacuum distillation unit and hydroprocessing unit. Since corrosion proceeds to general corrosion and occurs in a high temperature environment, it is a type of corrosion that can lead to a large fire explosion when a leak occurs.

Reduction Of Conservatism In SSC Testing For Sour Gas Well Tubulars

Product Number: 51322-17776-SG

Martensitic stainless steel (MSS) well tubulars are favorable due to their high strength and relatively low cost and are therefore widely applied in the Oil & Gas industry. This is especially the case for 13Cr and Super13Cr grades, which are often selected for mildly sour gas fields, where a relatively low content of H₂S is present. When selecting martensitic stainless steels for sour service, the susceptibility to Stress Corrosion Cracking (SCC) and Sulfide Stress Cracking (SSC), determined by standard laboratory tests, are the most important selection criteria.

Refinement Of Citric Acid Passivation Methods And Comparison To Traditional Nitric Acid Based Chemistries

Product Number: 51322-17628-SG

Author: David G. Enos, Derek Wichhart

Publication Date: 2022

$20.00

Traditional solutions for the chemical passivation of stainless steel are nitric acid based, with the addition of sodium dichromate as an inhibitor for precipitation hardened and free machining stainless steels. These passivation chemistries are difficult to handle from an environmental health and safety point of view, particularly the dichromate inhibited versions. Citric acid passivation has been pursued as a replacement for both nitric acid and inhibited nitric acid based chemistries for many years, and has been incorporated into consensus specifications such as ASTM A967 and SAE AMS2700.

Research On Cluster Well Group Casing Cathodic Protection For Field Test And Optimization Of Anode Bed

Product Number: 51322-17724-SG

Deep well casing is an important part of oilfield production. In the long service life of well casing, corrosion can result in wall thinning and even perforation of the casing due to contacting with soil, water and other naturally occurring substances within the formation. The most economic and effective method to decrease corrosion of well casing is cathodic protection (CP). However, the vertical depth of casing is several kilometers, and CP current requirements of casing in different layers are quite different. At the same time, the conductivity of different formations will affect the distribution of CP current.
