... of Zhu and Free, and clearly shows how the ratio of the components in either the oil or water phases rarely matches the composition ratio in the neat product. 1 As a result, if the performance of a production chemical is tested in a single phase e.g. corrosion inhibitor testing in brine only...

... Abstract Vapor corrosion inhibitors can be more volatile during elevated processing temperatures. It is critical that amount of VCI mass loss is engineered into the final product design. This paper focuses on a study where different vapor corrosion inhibitors are tested for mass-loss...

... Abstract Vapor corrosion inhibitors (VCI) are volatile chemistries and eventually they diminish at the source to provide the necessary protection on valuable assets. Shipping and Storage Covers with vapor corrosion inhibitors are used to protect military equipment, wind energy assets and other...

... ABSTRACT Corrosion inhibition is often the preferred choice of internal corrosion control of carbon steel pipelines and downhole tubulars for many oil and gas operators. The selection of a corrosion inhibitor (CI) is often system dependent because a CI that performs well under one set...

...-effective corrosion mitigation method is by continuous injection or batch treatment of corrosion inhibitor in production pipelines. Inhibitors are chemical compounds which can protect a metal surface either by the formation of a protective film layer or by reducing the corrosivity of an aggressive...

.... Monitoring an AST bottom corrosion and VCI effectiveness is an important factor in determining the bottom plate corrosion rate, and in taking preventive action such as application of vapor corrosion inhibitors (VCIs). ER probes are based on the bulk resistance measurements; change in element resistance data...

... a newly developed non-phosphorus program to solve these challenges. This novel program is a blend of proprietary scale and corrosion inhibitors. It provides excellent anodic and cathodic corrosion control of mild steel in a variety of water matrices (from soft water to high chloride water), and it widens...

... or cationic corrosion inhibitors might be the proper choice. Organic substances with a positive charge and their salts are mostly such inhibitors. Critical concentration of chlorides was investigated for fresh and carbonated concrete pore solution. Corrosion inhibition efficiency was evaluated by means...

... ABSTRACT The oil and gas industry utilizes surfactant-type organic corrosion inhibitors to mitigate internal pipeline corrosion. Changes in corrosion rates due to inhibitor addition have been related to adsorption isotherms as a function of the inhibitor concentration. However, the question...

... ABSTRACT The Oil and Gas Industry has gathered extensive and positive experience of applying corrosion inhibitors to control carbon steel corrosion in CO 2 and H 2 S environments. Occasionally, asset failures caused by corrosion are observed due to an erroneous application of corrosion...

... in a concentration of 15 000 mg/L. The gaseous part of the medium consists of H 2 and/or CO 2 . Tests are performed with or without a corrosion inhibitor and last 30 days. In general, the examined steel grades show a good resistance to hydrogen embrittlement. INTRODUCTION To achieve the climate goals, so-called...

... pipelines exposed to CO 2 environments is by injecting corrosion inhibitors. Most CO 2 corrosion inhibitors used in industry are organic compounds containing nitrogen, oxygen and/or sulfur. 1,2,3,4 The inhibitive action of these compounds is due to their adsorption at the metal surface. This process...

... such as gasoline, NACE TM-0172 method was carried out to qualify corrosion inhibitors for the pipeline. This method uses clear hydrocarbon product without considering the impact pipelines solids may have on the inhibitor performance. In this work we modify the NACE TM-0172 method to include the effect of solids...

ABSTRACT The relationship between corrosion inhibitor adsorption and micellization processes of different types of inhibitor molecules has been evaluated using a recently developed experimental approach. The approach involved integrating the following experimental methodologies - Capacitance...

Root-cause analyses conducted by several companies in both conventional and unconventional fields revealed that severe internal corrosion was caused by a low fluid flow velocity, an increasing water cut...

... years ago. Several research activities have been carried out since then to identify the main corrosion mechanisms and to propose appropriate mitigation techniques. Among them, the use of volatile corrosion inhibitors (VCI) seems very promising. However, the industry now suffers from a lack...
