Organic corrosion inhibitors (CI) have widespread use in the crude oil refining industry for corrosion protection and mitigation.¹ An effective corrosion inhibitor is a chemical substance that is applied in low concentration into a stream which suppresses or mitigates a corrosion mechanism.^,2,3,4 Inhibitors can be classified into two classes: adsorption or film-forming with organic inhibitors falling under the adsorption class. In this type of inhibitor a self-assembled structure is formed, where an array of hydrocarbon tails extend away from the metal surface and the polar groups (e.g., N in amines) chemisorb onto the metal surface.² Over the years, certain classes of inhibitors have been established as industry standards to confront specific corrosion mechanisms encountered throughout the refinery process. Examples include, filming and neutralizing amines used in crude units to combat aqueous corrosion; polysulfides used in FCCU to combat hydrogen blistering, cracking and embrittlement; P-based chemistries to combat naphthenic acid corrosion.⁵

Chemical Prevention of Corrosion-Induced Premature Well Failures Using a Novel Lubricity Mitigation Strategy

The production of hydrocarbons from a reservoir involves the drilling and interaction of a well with a reservoir, which initiates the natural flow of the hydrocarbons from the virgin reservoir to the surface. However, as production continues, the reservoir pressure is depleted, which results in a reduction of the hydrocarbon production rate due to reservoir maturity. This is usually accompanied by increased water-cut levels and a corresponding decrease in gas production, which may not only reduce but completely stop the flow of fluids from a well.

The crude oil produced by fracking or hydraulic fracturing method are high in sulfur content (0.5%)1. The vast majority of vessels that are used in the petrochemical industry to store and transport materials are constructed using Carbon steel. Coating linings used for corrosion protection inside of vessels and tanks must perform under severe conditions such as an exposure to corrosive gasses ( H₂S) and carbon dioxide as well as high temperatures, high pressures and often must withstand the cold wall effect and rapid decompression.

Chemical Resistant Waterborne Polyurethane Topcoats for Flooring

Product Number: 41205-216-SG

Author: Karl H. Wuehrer

Publication Date: 2005

$20.00

This paper gives an update on the latest developments of the new generation of waterborne Polyurethane Topcoats (PU topcoats) for flooring which were presented during the annual SSPC meeting October 2003. Topcoats are commonly used in the construction industry over functional floor coatings or as sealers for concrete.

Different refiners have a variety of procedures in place for hydroprocessing reactor and reactor system shutdowns, depending on the scope of the work to be performed during the downtime. If activities are to be performed inside the reactor (e.g. inspection, maintenance, catalyst changeout, etc.) such that the reactor must be opened to air, shutdowns must include steps to address the various hazards. These same steps must also be applied to associated process equipment related to the reactor system susceptible to similar hazards and damage mechanisms.

Chemistry Change Of CRUD With Various Metal Ion Concentration Conditions In PWR Fuel Cladding

Product Number: ED22-17313-SG

Publication Date: 2022

$20.00

Since 1960s, CRUD induced problems become an issue in PWR power plant. To enhance economic efficiency of PWR, the burn-ups of nuclear fuel have been increased. In the reactor core, some unexpected power shifts, which shows negative axial offset from prediction, have been observed. This phenomenon is called by AOA (Axial offset Anomaly) and it seems to be caused by deposits on the upper side of fuel cladding surface which is called CRUD.

Chloride-induced Corrosion of Reinforcing Steels Used in Concrete Structures at Various Temperatures

Publication Date: 2023

Steel rebar in concrete is in a passive state due to the high pH of concrete. The hydroxyl (OH-) ions in highly alkaline concrete pore solution act as inhibitors and promote passive film stability, while chloride ions lead to passive film breakdown. Leckie and Uhlig1 first explained the counter effect of inhibitor action with chloride concentration. They proposed a competition between the inhibitor and chloride anions for adsorption on the passive surface.
