CPE341 Petroleum Corrosion Technology Syllabus:

CPE341 Petroleum Corrosion Technology Syllabus – Anna University Regulation 2021

OBJECTIVE:

 To understand the types of corrosion found in the petroleum industries. This course will provide the student with knowledge of the analytical methods needed to diagnose, treat, and monitor corrosion to reduce costs, protect the environment, and increase safety.

UNIT I

Introduction to corrosion control. Definitions – Materials involved – Basic corrosion principles – corrosion rate. Electrochemical reactions. Electrode potentials – passivity – temperature – pressure – velocity – conductivity – pH – dissolved gases. Corrosion in oil and gas production.

UNIT II

Forms of corrosion – uniform corrosion – Pitting – Galvanic corrosion – Intergranular and weld corrosion – Selective Leaching – Stress corrosion. Impingement – Hydrogen embrittlement – Corrosion fatigue.

UNIT III

Role of oxygen in oil filed corrosion- down hole and surface equipment – water flood. Removal of oxygen, analysis and criteria for control. Role of carbon dioxide (CO2) in corrosion-Effect of temperature and pressure – Corrosion of well tubing and other equipments. Role of hydrogen sulphide (H2S)-Corrosion in downhole, surface, storage and pipelines.

UNIT IV

Corrosion prevention methods – Principles of operation and applications systems. Cathodic protection – Galvanic systems – Corrosion prevention coatings- Corrosion prevention inhibitorstypes of corrosion inhibitors- Inhibitor selection and injection.

UNIT V

Inspection and corrosion monitoring. Oil treatment corrosion – crude oil properties – desalting sweetening processes. Corrosion in oil storage tank corrosion- oilfield and oil treating facilities-oil/ gas pipelines -offshore platforms- subsea systems.

TOTAL: 45 PERIODS
