... ABSTRACT It is well known that the inhibitor efficiency is encumbered by many variables, such as temperature, pressure, pH, flow speed and chemical composition of the production fluid. Salt content of formation water varies dependent on the location and sometimes exceeds more than 10...

... ABSTRACT The novel indolizine derivative inhibitor for acidizing shows an effective corrosion inhibition without the synergism of propargyl alcohol. The inhibitive indolizine derivatives were generated from BQC (Benzyl Quinolinium Chloride, a commonly used key compound in acidizing inhibitor...

... dynamic simulation. The adsorption of APs on the surface of N80 steel obeyed Langmuir isotherm. Potentiodynamic polarization study confirmed that inhibitors are mixed type with cathodic predominance. Molecular dynamic simulation was applied to search for most stable configuration and adsorption energies...

... ABSTRACT This paper will outline the development of a new Yellow Metal corrosion inhibitor with improved corrosion control capabilities when compared to traditional triazole technology. A four-year R&D effort has led to a new patent pending molecule that develops a thicker, more robust...

... ABSTRACT The Phenylalanine based corrosion inhibitor 2-(3-(1-carboxy-2-phenylethyl)-1H-imidazol-3-ium-1-yl)-5-methyl-3-phenylpropanoate (IP) was synthesized by the condensation of phenylalanine, 2-oxopropanal, and formaldehyde and characterized by the FTIR and NMR spectroscopy. The corrosion...

... of the system, during and after testing become a major concern, therefore, application of inhibiting system is required. Vapor-phase corrosion inhibitors (VCI), can be added to water in small concentrations to prevent corrosion during testing, or wet storage and after testing. These inhibitors are to prevent...

... ABSTRACT Corrosion inhibitors are widely used for prolonging the lifetime of oil production facilities. In practice, it is important to quickly screen the effectiveness of a certain kind of corrosion inhibitor before its use in a target environment. However, the evaluation is actually quite...

...) and several synthetic homo- and copolymers containing a variety of functional groups has also been studied. The results indicated that performance of additives tested strongly depends on the inhibitor architecture. Based on the data collected, the additives may be ranked as follows: homo- > bio...

... of chemical inhibitors is the most effective strategy. Additives are being utilized successfully for several inorganic mineral scales (eg. CaCO 3 , BaSO 4 , etc.), however, silica is a case with intriguing idiosyncracies. Its control requires designed strategies based on its unique chemical nature. Thus...

... ABSTRACT There is a growing demand for combined Corrosion Inhibitors (CI) and mineral Scale Inhibitors (SI) for the oil and gas production industry. The products are convenient when logistics is an issue and there is only one injection point. Developing these types of products can sometimes...

... ABSTRACT We have performed all-atom classical molecular dynamics simulations of aggregation and adsorption of different corrosion inhibitor molecules on metal surfaces. We report free energies of aggregation and adsorption of imidazolinium-type (henceforth referred to as imid) and quaternary...

.... The differences in inhibition efficiency were attributed to molecular characteristics, including flexibility and hydrogen bonding capacity. Both inhibitors acted as nucleation and as crystal growth inhibitors INTRODUCTION The formation of calcium sulphate deposits occurs in a wide variety of processes...

...-, and synthetic homo- and copolymers. The experimental results show that performance of polymers as CaOx inhibitors strongly depends on polymer architecture and type and charge of comonomers. In general, polymers containing carboxyl group perform better than co- and terpolymers containing hydrophobic and bulky...

... ABSTRACT Application of inhibitors is an established and cost-effective method to mitigate internal corrosion of mild steel pipelines in the oil and gas industry. Conventionally, surfactant-type organic inhibitors are frequently applied based on their critical micelle concentration (CMC...

... ABSTRACT Currently, most cooling water treatment programs utilize phosphate for corrosion control and apply scale inhibitor to reduce the potential calcium phosphate deposition on heat exchangers. A non-phosphorus program would reduce or eliminate the need for calcium phosphate scale...
