treated sea water is the most significant source of water and surfactant floods. the various chemicals employed in treatment plants should be compatible with surfactant systems. based on surface tension experiments, the activity of these chemicals is examined over a wide range of concentrations in different solutions, including distillated water, sea water by using three types of surfactant mix...

Vanillin is an interesting corrosion inhibitor because of its safe use and high solubility inwater. The effect of vanillin on the corrosion inhibition of carbon steel in 1.0 Mhydrochloric acid solution has been studied using potentiodynamic polarization,electrochemical impedance spectroscopy (EIS) and electrochemical noise (EN) techniques.The effect of temperature on the rate of corrosion in th...

In this study, the ability of lithium nitrite and amino alcohol inhibitors to provide corrosion protection to reinforcing steel was investigated. Two types of specimens-reinforcing steel and a reinforced concrete prism that were exposed to chloride ion levels resembling the chloride attack environment-were prepared. An autoclave accelerated corrosion test was then conducted. The variables teste...

This study set out to examine the cystoseira gibraltarica extract (CG) as an environmentally sustainable corrosion inhibitor for carbon steel in 1.0 M HCl medium. The corrosion inhibiting effect has been studied by conventional methods such as gravimetric (weight loss) and electrochemical (EIS and PDP) methods. All the methods used in this study confirm that cystoseira gibraltarica extract has ...

The self-assembled monolayer (SAM) was prepared using octadecyl trichlorosilane (OTS) in distilled solution on the copper surface. The effect of inhibitor concentration on the rate of inhibition efficiency and corrosion rate in corrosion medium on copper by using polarization curves, electrochemical impedance spectroscopy (EIS), scanning electron microscope (SEM) was studied. The results showed...

A corrosion inhibitor is a chemical substance which, when added in small concentrations to an environment, minimizes or prevents corrosion [I]. Corrosion inhibitors are used to protect metals from corrosion, including temporary protection during storage or transport as well as localized protection, required, for example, to prevent corrosion that may result from accumulation of small amounts of...

Corrosion of metal surfaces amongst other problems is one major disaster militating against proper functioning of the oil and gas and other manufacturing industries. To therefore lessen the risk, organic corrosion inhibitors have been applied to lessen the rate of corrosion and its effects. However, materials with optimal properties, better than content that allow corrosion are used for this em...

A mini-flowloop was developed to study CO2 corrosion and corrosion/erosion interactions, and to assess the effectiveness of inhibitors under conditions that simulate multi-phase pipelines. The miniflowloop was used to study the effect of testing time, steel chemistry, velocity, temperature, fluid chemistry, sand and inhibitors on corrosion rates. The measured corrosion rates in inhibited and un...

The corrosion behavior of mild steel (Ck 45) in 3.0 M H3PO4 solution in the absence and presence of penicillin G was studied using potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) techniques. The best inhibition effect at 10 mM of drug was a marked characteristic of the inhibitor. It was found that the inhibition efficiency of the inhibitor...
