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.

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.

Enhanced Oil Recovery: Localization of corrosion during polymer flooding

Product Number: 51323-18888-SG

Author: Moritz Schwingenschlögl, Gunther Ball

Publication Date: 2023

$20.00

Traditionally, oil recovery operations are subdivided into primary, secondary and tertiary stages. EOR is commonly classified as tertiary recovery, where gases, liquid chemicals and thermal energy can be used to enhance the displacement of reservoir fluids. Different sources divide EOR into two to five categories, one particular method, polymer flooding, is based on increasing the fluid viscosity by adding a polymer to the injected water. Polymer EOR is a mobility-control process using a polymer-augmented waterflood, typically a solution of partially hydrolyzed polyacrylamide (HPAM) or polysaccharides, which is injected to displace oil towards production wells.

Evaluating the Flash Rust Protection of Water-Based Cleaners and Their Role in Surface Preparation

Product Number: 51324-20745-SG

Author: Lisa Marston; Luke Stone

Publication Date: 2024

$40.00

In metalworking processes, contaminants can interfere with future processing steps and may accelerate corrosion on metal parts. As such, a cleaning step is often implemented prior to coating or packaging finished parts. Industrial cleaners are typically water-based with blends of surfactants, co-solvents, chelating agents, and/or flash rust inhibitors. While accelerated corrosion tests such as humidity and salt fog exist, they are typically too aggressive for the evaluation of flash rust inhibitors in cleaners which are not meant to provide long-term corrosion protection. There is a need in the industry for a quick and reliable way to select a cleaner that meets the needs of the application and is compatible with the overall process. A screening method to compare the flash rust protection ability of various water-based cleaners was investigated. Modified vapor inhibiting ability (VIA) testing and linear polarization resistance (LPR) tests were performed on carbon steel plugs treated with several cleaners. Industry standards currently recommend that any detergent or cleaner be removed from metal surfaces prior to applying coatings. When evaluating cleaning processes where coatings will be subsequently applied, adhesion testing should be paired with the screening test. The effects of various cleaners on adhesion of a waterborne acrylic coating were investigated.

Formulated Didecyl Dimethyl Ammonium Bicarbonate/Carbonate (DDABC), a Multi- Metal Corrosion Inhibitor with Relevance to Commercial Surface Preparation and Coatings Technologies

Product Number: 41207-306-SG

Author: Thomas C. Bedard, T. David Burleigh, Joseph Kimler

Publication Date: 2007

$20.00

A new water-soluble quaternary ammonium compound, didecyldimethylammonium bicarbonate/carbonate (DDABC), has been evaluated as a corrosion inhibitor via standard electrochemical tests on steel and shown to be highly effective. At the proper dilution, the inhibitor migrates to the metal/solution interface and forms a monomolecular film on the anodic sites.

Gearbox Corrosion Mitigation During Storage and Intermittent Operation

Product Number: 51324-20747-SG

Author: Pavlo Solntsev; James Holden

Publication Date: 2024

$40.00

Gearboxes are one of the most critical pieces of equipment in a plant. Downtime because of gearbox failure can significantly impact manufacture and be very costly. An additional inventory of spare gearboxes is needed to minimize the effect of the loss. All gearboxes operating and during storage are susceptible to corrosion due to moisture condensation on the metal surfaces. The work describes oil additives that protect gearboxes during operation, layup, and warehouse storage. As was proved, the corrosion can be mitigated by adding a Vapor Corrosion Inhibitor (VCI) to the system. The testing methodology to verify the effectiveness of the oil additives, as well as compatibility with the base oil, was presented. Based on the present work, a specification for gearbox preservation during storage was developed.

Impact of CO2 Partial Pressure on Electrochemical Measurements at High Temperatures

Product Number: 51320-14584-SG

Laboratory testing of corrosion inhibitors under high temperature high pressure (HTHP) conditions is challenging. HTHP testing has been traditionally performed in closed systems with fixed liquid/gas volume and testing results are usually influenced/compromised by the accumulation of ferrous ions and corrosion products. The aim of the work is to optimize corrosion inhibitor testing conditions at HTHP to generate results of better reliability. The corrosion of carbon steel by CO2 at HTHP was assessed using small working electrodes of large liquid volume-to-sample surface area in autoclaves. The effect of CO2 partial pressure was also investigated. The blank and inhibited corrosion rates were monitored by linear polarization resistance (LPR) and the morphology of coupon surface was measured by vertical scanning interferometry (VSI). The testing results were deemed to be more representative of the field service environment when the amount of ferrous ions and corrosion products was reduced due to the usage of small working electrodes.

Publication Date: 2022

Corrosion resistant alloys (CRAs) are used for many pipeline and wellhead components associated with oil and gas production environments but may be considered too costly for longer crude oil and natural gas production lines. Mitigation of internal corrosion for these types of pipelines is normally carried out by batch treatment or continuous injection of corrosion inhibitors, especially the surfactant type of organic inhibitors, which are more economical than using a CRA.
