Corrosion Challenges in Aromatic Extraction Unit

Product Number: MECC23-20253-SG

Author: Ameer Hamza; Rakan M Samman

Publication Date: 2023

Extraction units are typically utilizing the solvents to dissolve the aromatics compounds such as benzene, toluene, and xylenes from hydrocarbon stream. These solvents are organo-sulfur compound which is readily soluble in the water due to high polarity of oxygen-sulfur compounds.

Fresh solvents are not considered to be corrosive for carbon steel and stainless-steel components, however improper application and handling of this solvents will result in degradation of this products.

Alloy 35Mo is a new versatile Ni-alloy which has corrosion and mechanical properties comparable to advanced Ni-base alloys, with the benefit that it can be processed like a stainless steel. The alloy was recently designated UNS N08935 with the composition 35Ni-30Fe-27Cr-6.5Mo-0.28N and has a PREN of 52. This paper presents the mechanical and physical properties of the material and results from corrosion testing. Corrosion results from general corrosion testing in acid environments, together with results from stress corrosion cracking testing in chloride environments and pitting corrosion testing show that UNS N08935 can be used in harsh environments in many applications, e.g. heat exchangers in refinery industry and equipment with seawater cooling. UNS N08935 also has high mechanical strength, and good weldability has been shown using Alloy 59 as filler metal.

Corrosion in acidic solutions frequently leads to equipment failure in industry. The ability to model corrosion in acidic solutions is thus necessary to increase asset integrity. A prerequisite for any corrosion model is the accurate knowledge of solution thermodynamics. In this study, a previously developed electrochemical module has been integrated with the Mixed-Solvent Electrolyte (MSE) thermodynamic model. MSE has been previously proven to accurately represent the behavior of solutions, including solubility limits, pH, and transport properties. Here, the accuracy of MSE in predicting speciation in acidic systems is demonstrated. The electrochemical module, which incorporates partial anodic and cathodic reactions, can model active corrosion, active-passive transition, as well as dissolution in the passive state. The model is shown to quantitatively predict the corrosion rates of two duplex stainless steels, i.e., 2507 (UNS S32750) and 255 (UNS S32550) in acid mixtures containing both oxidizing and non-oxidizing acids. The effects of aggressive (fluoride and chloride) and inhibitive (nitrate) species are also accurately predicted. Simulated polarization curves are presented for the mixed acid systems to illustrate the effect of different species on the anodic and cathodic processes.

Recent Advances On The Influence Of Microstructural Characteristics On Corrosion Resistance In H2SO4 Of Anodized Titanium

Product Number: 51322-17589-SG

Industrial usage of Plasma Electrolytic Oxidation (PEO) has grown consistently in recent years, thanks to the improved characteristics imparted to the oxide film in terms of surface adhesion, hardness, crystallinity, uniformity, and corrosion resistance. The metallic substrate is not subjected to elevated temperature and the overall equipment complexity is relatively simple, making the technique a good candidate for surface functionalization. In PEO treatments, high voltages are employed (~ 150-750 V 1) allowing for the formation of an insulating, or at least semiconductive, oxide layer that’s limits ion transport responsible for the initial coating growth. Beyond the spark voltage (prerequisite the enter the PEO regime) oxidation does not occur only as the result of a continuous flow of ions but rather it takes place after the cooling of a plasma discharge.
