December MSChE Defense for Kevin Blake

Kevin Blake has successfully defended his thesis on December 18th 2018. Kevin's thesis topic is Experimental Characterization and Modeling of Wettability in Two-Phase Oil/Water flow in the Annular Flume Apparatus. His research is focused on the hydrodynamic characterization of the annular flume apparatus, which is designed to simulate pipeline flow in a small-scale setting, making experimentation of oil/water two-phase flow more timely and efficient than traditional testing. In this study, Kevin performed numerical modeling of single phase flow in the annular flume to produce computational fluid dynamics (CFD) simulations which were then validated with experimental hydrodynamic measurements; namely, tangential velocity, wall shear stress, and phase wetting. The results of the CFD simulations were used to visualize the flow characteristics in the annular flume and to modify a key parameter of the water wetting model developed by the ICMT. Kevin is currently working as a Product Engineer with Stirling Technology Inc., Athens OH.



 

December PhD Defense for Yuan Ding

Yuan Ding has successfully defended his dissertation on December 10th 2018. Yuan's dissertation topic was Mechanistic Understanding of CO2 Corrosion Inhibition at Elevated Temperatures. His dissertation was under the supervision of Professor Marc Singer. Yuan's research was focused on the role of high temperature on the corrosion behavior with the presence of corrosion inhibitor. The results of this research highlighted the importance of considering the formation of corrosion products when developing inhibition strategy at elevated temperatures. It was observed that the formation of Fe3O4 corrosion product at elevated temperatures has a critical role in the performance of inhibitors. The corrosion rate was dominated by the development of Fe3O4 at 150oC if the inhibitor was injected after a short period of pre-corrosion (30 minutes). However, with further limiting the formation of corrosion product, the inhibitor can still decrease the corrosion rate, although poorly, at 150oC . The work also enabled the development of appropriate experimental setups and procedures to evaluate accurately inhibitor performances at high temperatures. This brought in a significant improvement in the understanding of corrosion inhibition at elevated temperatures, elucidating some aspects of inhibition performance that had been overlooked, and allowing better corrosion management strategies for high temperature applications. Yuan is currently looking for job opportunities in both industry and academics.



 

December PhD Defense for Ezechukwu Anyanwu

Ezechukwu Anyanwu has successfully defended his dissertation on December 14th 2018. Ezechukwu's dissertation topic was The Effect of Flow on the Development and Retention of Iron Sulfide Corrosion Product Layers. His research is focused on the impact of flow on the development and retention of iron sulfide corrosion product layers. In his study, he developed two experimental setups which were used to generate flow conditions required for his corrosion studies. The flow related mass transfer rates and wall shear stress in these systems were also characterized using electrochemical method and computational fluid dynamic (CFD) technique, respectively. He went ahead to study the impact of iron carbide on the development of iron sulfide layers, and also the impact flow on the development and retention of these corrosion product layers. Results from this study suggests that iron carbides not only influences the morphology of the iron sulfide layers developed, it is also critical to the overall protectiveness of the layers especially in high fluid velocity conditions. Ezechukwu has a conference paper accepted for NACE 2019 and four journal publications in preparation. He accepted an Associate position in the Materials & Corrosion Engineering practice at Exponent, Menlo Park CA.



 

October PhD Defense for Ru Jia

Ru Jia has successfully defended his dissertation on October 12th 2018. Jia's dissertation topic was Mechanisms of Microbiologically Influenced Corrosion Caused by Corrosive Biofilms and its Mitigation Using Enhanced Biocide Treatment. His advisor was Professor Tingyue Gu. Jia's research was focused on microbiologically influenced corrosion (MIC) mechanisms and mitigation at the Institute for Corrosion and Multiphase Technology, Ohio University. He proved that H2S is not the primary contributing factor in carbon steel MIC by sulfate reducing bacteria (SRB). Sulfate reducing archaeon (SRA) was confirmed to be corrosive against C1018 carbon steel at 80oC because SRA can utilize extracellular electrons for sulfate respiration just like SRB. He also showed that a nature-inspired anti-biofilm peptide at ppb (w/w) levels are found in lab tests to enhance a popular commercial biocide in treating a corrosive oilfield biofilm consortium on C1018 carbon steel. During his doctoral study, he has published more than 20 peer-reviewed journal papers with 14 of them first-authored. Ru is currently working as a postdoctoral research scientist at Texas A&M University.



 

October PhD Defense for Aria Kahyarian

Aria Kahyarian has successfully defended his dissertation in October 2018. Aria's dissertation topic was Mechanism and Prediction of Mild Steel Corrosion in Aqueous Solutions Containing Carboxylic Acids, Carbon Dioxide, and Hydrogen Sulfide. His PhD research was aimed to answer one of long-lasting questions in pipeline corrosion of mild steel: How CO2, H2S and carboxylic acids affect the aqueous corrosion of mild steel? He initiated a kinematic investigation of the electrochemical behavior of mild steel in such environment. Using polarization data along with detailed quantitative analysis based on comprehensive mathematical models, he showed that neither carbonic acid nor hydrogen sulfide or carboxylic acid are electrochemically reduced during the corrosion process. His findings showed that all these species act merely as buffers at the vicinity of the metal surface. This process, which is referred to as "buffering effect", is demonstrated to be the cause of the accelerated corrosion in presence of these species. The buffering effect was shown to be an inherent property of any weak acid. The results and discussions developed during this investigation introduced a new perspective to the corrosion of mild. He showed that all the above mentioned corrosion scenarios are in fact example of one generic corrosion mechanism: aqueous corrosion in presence of weak acids. Aria showed that the severity of the effect of a weak acid on mild steel corrosion can be readily predicted based on its chemical properties, and introduced a grouping on that basis, in order from higher to lower aggressivity: strongly buffering weak acids with pKa below 5 such as carbonic acid and acetic acid, mildly buffering weak acids with pKa between 11 and 5, such as hydrogen sulfide and bicarbonate ion, and on-buffering weak acids with pKa above 11, like water and hydrogen bisulfide. The findings of Aria's research are collected in eight peer-reviewed journal publications, with four more in preparation. He is currently with Apple.



 

FREECORPTM 2.0 IS HERE

Given the great popularity of FREECORPTM 1.0, which was launched in 2008, we are now releasing the second version, FREECORPTM 2.0. In the past 10 years, FREECORPTM 1.0 has been downloaded over 10,000 times by users from all over the world. Since 2008, we have received feedback and suggestions from more than 250 users. Those messages made us realized that there are features that we could have implemented better. Moreover, our understanding of the physicochemical phenomena underlying this type of corrosion has improved significantly over the past decade and we wanted to bring all that back to the FREECORP community. This has led us to development of FREECORPTM 2.0 and several main improvements were made in FREECORPTM 2.0 over FREECORPTM 1.0.
