Additionally, summary data will be presented that compares the performance...

...Recent Ionic Model Improvements A key weakness in the original commercially available ionic model was that it could not account for more than one amine reaction with HCl at a time. In the mid-2000s Mixed Solvent Electrolyte ^† (MSE) model was developed by a joint industry project (JIP...

... in the extraction process, are two disadvantages associated with these traditional techniques. ⁴ Solid Phase Microextraction Abstract Amine-based corrosion inhibitors are added to the crude oil streams to protect the pipelines from corrosive attacks by oxygen. Amine residuals should be monitored...

... The model is suitable for simulating the phase behavior in refinery overheads because it is capable of simultaneously reproducing: Vapor-liquid and liquid-liquid equilibria between vapor, aqueous, and hydrocarbon-rich liquid phases Partitioning of various basic (e.g., amines and ammonia) and acidic (e.g...

... * currently at Mustang Engineering, L.P Abstract New technologies for on-line monitoring and corrosion prediction to improve amine operation and reliability in Amine units is presented and discussed. A software package developed for corrosion prediction, allows to simulate the corrosive...

...The reaction of an amine with hydrogen chloride (HCl) in crude unit vapor streams is a well-researched phenomenon. ¹ The salts formed by these reactions can produce highly aggressive localized corrosion as well as fouling in crude unit columns, pumparound circuits and overhead...

... and CO₂ rich amine solution flows from the bottom of the absorber to the flash drum. Rich amine then flows from the flash drum through the lean/rich amine heat exchanger and on to the amine regenerator column. In the regenerator column, the acid gases are stripped from the solution by means of heat...

... environments include aqueous solutions containing ammonia, organic amines or certain concentrations of chloride ions at elevated temperature. This type of phenomenon has been rarely reported for cupronickel alloys, which are regarded as being highly resistant to stress corrosion ⁶ cracking. However...

Indoor air quality issues include the use of amines in steam used for humidification, sterilization and food preparation. Control of feedwater...

...Neutralizing amines are typically added to the system in direct proportion to the amount of CO₂ in the steam and are usually dosed at the concentration required to obtain condensate in the desired pH range. Neutralizing amine programs are most effective when fed to maintain a condensate...

...Abstract The causes and the prevention of carbon steel corrosion in refinery amine systems are reviewed. The corrosive agents are acid gases, ammonia, oxygen, heat stable salts, and amine degradation products. Corrosion mechanisms are provided for carbon steel exposed to amine solutions...

... at 0 °C, 10 °C and 40 °C. It was found that hydrogen sulfide saturated anhydrous methanol exhibits similar corrosiveness for steel than hydrogen sulfide saturated water. Higher homologues showed decreasing corrosiveness. The diols and glycerols inhibit the hydrogen sulfide corrosion. Filming amines...
