A lot of oil and gas facilities face corrosion problems because the production fluid contains some corrosive components represented by CO₂. Generally, corrosion inhibitors are used in order to mitigate corrosion problems of tubing and pipeline. Imidazoline is known as one of the active ingredients of corrosion inhibitors and widely used in the oil and gas industries. However, imidazoline-type inhibitor is easily hydrolyzed to amide if water mixes into it.

Due to the increase in world’s population and technologies, and the limited fossil fuel reserves, efforts have been taken to seek alternative energy resources, such as bioenergy that is produced from renewable biomass, to meet the increasing need for energy. The feedstocks for bioenergy production can include the waste biomass from forestry and agricultural sectors and various industries such as food processing industry and pulp and paper industry, making a profit while saving costs from waste management.

Effect Of Organic Solvent On Corrosion Inhibition of Mild Steel in CO2 environment

Product Number: 51322-17942-SG

Author: Xi Wang, Shuai Ren, Yi He, David Young, Marc Singer, Maalek Mohamed-Said, and Sheyla Camperos

Publication Date: 2022

Corrosion inhibitors is commonly used to combat internal corrosion of mild steel pipelines in oil and gas production and transmission systems. Since the corrosive environment and flow conditions could vary in different fields, small scale laboratory testing is essential to determine the effectiveness of inhibitors in specific corrosive environments. To ensure the accuracy of inhibitor dosage in a small-scale lab setup, the inhibitor often needs to be pre-diluted before addition to the test electrolyte. This pre-dilution has the potential to lead to experimental errors. However, little information can be found about pre-dilution steps, and their influence on inhibition phenomena, in the open literature.

Effect Of Relative Humidity And Galvanic Couples On Stress Corrosion Cracking Of High-Strength Aluminum Alloys

Product Number: 51322-18015-SG

High-strength aerospace aluminum alloys, such as AA7075-T651, are susceptible to environmental assisted cracking (EAC) under the right combinations of stress, environment, and microstructure. EAC presents a serious risk to structures and equipment operated in corrosive conditions. Studies of EAC in aluminum alloys have highlighted the importance of both anodic dissolution and hydrogen embrittlement to EAC initiation and propagation.^1–4 The EAC response of alloys under variable atmospheric conditions is of particular importance for assessing material performance for aerospace applications.

Effect Of Soil Environment On Hydrogen Embrittlement Behavior Of X60 Steel

With the rapid development of China's economy, energy and transportation industries have developed rapidly, and more and more oil and gas pipelines and urban rail transit have been built and put into use. Urban rail transportation systems, such as subways or light rail, generally use direct current traction and backflow through the rail. Because the track is not completely insulated from the earth, it is inevitable that some electric current will be discharged from the track to the earth to form stray electric current, which will cause interference to the surrounding metal components such as buried oil and gas pipelines.

Effect Of Steel Surface Profile Peak Density On Rust Creepage

Product Number: 51322-17584-SG

Author: Russell Draper, Michael Beamish

Publication Date: 2022

$20.00

The spread of disbondment or corrosion from a scribe or holiday in a coating film, for which the terms rust creepage or undercutting are used in this paper is an important mechanism of coating degradation. The mechanism of rust creepage has been well studied by several authors who concur that the mechanism is driven by electrochemical reactions15. The reactions occurring at the discontinuity in the coating (scribe or holiday) involve an anodic reaction in which iron is dissolved. Adjacent to the anodic region, under the coating, a cathodic reaction occurs in which oxygen is reduced to hydroxyl ions.

Effect of Surface Conditioning on Corrosion Resistance Using New Vs. Traditional Abrasive Blasting Media Types

Product Number: 51220-291-SG

Publication Date: 2020

Surface conditioning is the first step in building efficient corrosion protection on a part or structure. Key concerns during this step include, how to create a stronger anchor-profile and how to efficiently remove previously coated, damaged, or corroded elements from a materials surface prior to coating. The ideal solution must consider three areas of the surface conditioning process: finish quality, cleaning efficiency and total cost.

Author: Devin Clark, Richard C. Ferguson & James W. Rawlins

Publication Date: 2016

Coating performance and longevity is highly dependent on the quality of substrate surface preparation. The effect of profile height, profile type (e.g., type of tool used to perform the prep, angularity of profile, etc.), extent of cleanliness, and amount of chloride contamination on coating performance were all studied to determine the correlation between these factors in an attempt to identify the primary factor in coating failure due to improper surface preparation.

Effect Of Temperature On Inhibition Efficiency And Data Analysis With Different Adsorption Isotherms

Publication Date: 2022

$20.00

In the oil and gas industry, long-distance transportation of petroleum and related products is usually carried out in large-diameter carbon steel pipelines. Water present with the oil, along with corrosive species such as CO₂, H₂S and organic acids, causes severe corrosion of the inner pipe walls.¹ An effective method of controlling corrosion is to continuously inject corrosion inhibitors into pipelines conveying oil-water mixtures. As corrosion occurs on water wetted metal surfaces, corrosion inhibitor (CI) molecules form protective films which retard electrochemical reaction rates at the water-metal interface,² thereby protecting carbon steel pipes against CO₂ ("sweet") corrosion and H₂S ("sour") corrosion. Most commercial CIs are a complex mixture of several compounds that contain surfactant-type active ingredients, such as imidazoline, amine, phosphate ester, and quaternary ammonium derivatives.

Pyrolysis processes of post-consumer plastics are a promising chemical recycling route and a good alternative to disposal. Nevertheless, these processes are challenging for metallic materials since chlorine containing materials or biological components inside the feedstock can yield HCl and H2S, respectively, during cracking. In combination with high temperatures of the reactor zone metallic construction materials can be attacked by high-temperature corrosion.
