The Chemical Engineering Department at Al-Nahrain University discussed the MSc thesis of student Sahar Khalid Aboud titled: 

"Cathodic Protection of Steel Structures with Regard to Potential Decay in The Presence of Refinery Wastewater Pollutants." 

The discussion committee, which took place in the Chemical Engineering Department Council Hall/College of Engineering on Monday, November 11, 2024, consisted of the following members: 

1. Prof. Nasir Aboud Issa, College of Engineering/Al-Nahrain University, Chair 

2. Assoc. Prof. Shaimaa Abdul Rahman Ahmed, College of Engineering/University of Baghdad, Member 

3. Dr. Ammar Abdullah Saud, College of Engineering/Al-Nahrain University, Member 

4. Prof. Basim Ubaid Hassan, College of Engineering/Al-Nahrain University, Supervisor 

The thesis was scientifically evaluated by the first scientific reviewer, Prof. Ali Hussein Abbar, University of Baghdad, Al-Khwarizmi College of Engineering, and the second scientific reviewer, Assist. Prof. Shakir Saleh Bahr, University of Babylon, College of Engineering, as well as linguistically by Assist. Prof. Hala Salman Hassan, College of Engineering/Al-Nahrain University.

In this work the Cathodic protection (CP) of carbon steel pipes was studied using Impressed Current (ICCP) and Sacrificial Anode (SACP) methods. Graphite and zinc electrodes were used in NaCl solutions with copper ion contaminants. The study examined CP efficiency, potential decay, electrode spacing, and anode-to-cathode ratios. Results showed changes in performance over time, highlighting the long-term effectiveness of both methods.

The thesis has been accepted as it meets the requirements for obtaining a Master degree.
