Chemical Inhibitors

 Most effective and latest technology in corrosion prevention for protection of boiler systems, turbines, pumps, storage tanks, heat recovery steam generator systems, generators, and piping systems. Protection of the system is based on “temporary” corrosion inhibitors.

This study examines the effectiveness of various types of corrosion inhibitors in a waterborne styrenated acrylic coating, based on salt fog results, (ASTM B117). All of the samples were made using high speed dispersion.

An analytical method using fluorescence spectroscopy has been developed to measure inhibitor concentration. It enables dye transfer methods and promises a greater degree of accuracy.  The procedure can be performed in the laboratory or at the well site, and individual analysis can be done quickly.

Principles and work investigating various corrosion and scaling inhibitors for the production and process industries. The use of block-copolymers and hyperbranched oligomeric design in inhibitors is of a high interest.  Also involved are a number of analytical and testing methods

 There is a growing trend to supplement cathodic protection with Volatile Corrosion Inhibitors (VCI) beneath tank floors. This work is to investigate mutual compatibility and interactions of three different volatile corrosion inhibitors and cathodic protection.

The paper describes results of potentiodynamic and potentiostatic electrochemical tests carried out in alkaline solution, in the presence of chlorides, on binary mixtures with nitrite, dimethylethanolamine (DMEA), glutamine and benzoate.

Corrosion behavior of carbon steel in an in-house solvent was investigated in a pilot-scale post combustion CO2 capture process. Carbon steel specimens were placed where corrosion problems were previously found in the stripper column and the CO2-rich amine piping.

This paper presents new applications of Volatile Corrosion Inhibitors (VCI) inside new and/or existing out-of-service pipelines. The system utilizes a combination of soluble and volatile corrosion inhibitors that are directly applied into the pipeline.

This research was to determine if an iron carbonate (FeCO3) layer can be effective for prevention of CO2 corrosion of steel rebars, associated with production and use of carbonated calcium silicate cement-based concrete.

This paper discusses the product design philosophy for corrosion inhibitors used for CCTS (Carbon Capture, Transportation and Storage), which have to work in both vapor phase and liquid phase at the same time.

The main objective of this research was to evaluate the performance of different commercial inhibitors with emphasis on the impact of high flow velocities under highly corrosive conditions.

How different families of scale inhibitors impact corrosion inhibitors performance in the presence of each other. Fundamental properties of both chemistries and how their interaction can be understood at the molecular level.
