 Course Overview

 

Carbon dioxide (CO2) corrosion is a recognized integrity threat worldwide. CO2 corrosion modeling has been used at both the design and operation phases of oil and gas pipelines for the prediction of internal corrosion growth rates. Considerable gap exists between the prediction and the reality.

 

 

Since the classic carbon dioxide corrosion model published by C. DE WAARD and D. E. MILLIAMS in 1970s, more than a dozen of CO2 corrosion models have been developed over the past 40 years. Each of the model developers has incorporated their own laboratory and field data to produce a CO2 corrosion model.

 

The figure above shows a comparison of the measured corrosion growth rate and the corrosion growth rates predicted from twelve CO2 corrosion prediction models under a specific field condition.

 

None of the CO2 corrosion prediction models produced corrosion growth rate with reasonable accuracy. Without validation, facility owners and casual users of CO2 corrosion modeling programs have no way of knowing the accuracy or the reliability of the predicted corrosion growth rates.  The models differ in how it handles the calculation of pH, the treatment of fugacity, flow rate, scaling, oil wetting, effect of glycol, organic acids, NaCl and dissolved oxygen. Each model has its own limits, errors and uncertainties associated with the model. The user must evaluate the design and stream parameters and consider if any particular model can really be believed. In CO2 corrosion modeling, there is no such thing that one model fits all pipeline conditions. It is simply wrong for a contractor/consultant to use one (1) modeling software for all clients and under all pipeline conditions. Using CO2 corrosion modeling software is not like running an excel spreadsheet. The "all-in-all-out" approach in CO2 corrosion modeling is a formula for failure. The user of a CO2 corrosion model must assess the pipeline stream parameters, select suitable CO2 corrosion models, validate the selected model against the user's own or any 3rd party independent field/lab data before starting a CO2 modeling project.

 

It is always easier and better to validate the CO2 corrosion modeling software before commencing a modeling project than trying to validate the modeled results afterwards.

 

This 5-day specialized practical course covers fundamentals of corrosion, key factors influencing CO2 corrosion, and all the details on CO2 corrosion modeling for the prediction of internal corrosion in oil and gas pipelines. Specifically, the course will cover the overview of a dozen of empirical and mechanistic carbon dioxide corrosion models, CO2 corrosion model comparison, CO2 corrosion model selection, CO2 corrosion model validation and extensive hands-on modeling exercises.  A practical guide for CO2 corrosion modeling strategy is also presented.

 

This specialized practical course is available for in-house training, online and distance learning worldwide. It can also be customized to meet the specific needs of your organization.

 In-House Training Corrosion Courses

 

If you are concerned with corrosion in your business, in-house training is a great solution to train a group of employees from design, production, operation, quality assurance, inspection and maintenance, and technical sales and support on corrosion control and corrosion prevention technology. The contents of all corrosion courses can be customized to fit your organization's needs.

 

There is no minimum or maximum number of participants required for in-house training corrosion courses. We conduct the in-house training corrosion course at your company's premises and at a time convenient to your company. Requests for in-house training corrosion courses from overseas countries are also welcome.

 Corrosion Course-On-Demand

 

All our publicly scheduled corrosion short courses are conducted once a year. However, you do not need to wait for one year if you have missed any of the publicly scheduled corrosion courses as we have this unique corrosion course-on-demand scheme: we will conduct the course just for you on an one-on-one basis at a time and in a location convenient to you. This option costs significantly less than a full-scale in-house training program.

 Online and Distance Learning Corrosion Courses


All corrosion courses can be conducted through online or distance learning. An username and password will be emailed to course participants for accessing the online course materials. Alternatively, a CD-ROM containing the same online course material or a master hard copy of corrosion course notes can be sent to your organization. Instructions, course assignments, discussions and questions related to the corrosion courses are posted on the website. Free email support for online courses is provided for a period up to 12 months. A Certificate of Completion will be issued to participants who pass the online test with a score of 70% and above.

 PowerPoint Slides and Test Banks for Trainers, Instructors, Tutors, University Lecturers and Professors

 

If you are involved in teaching corrosion courses, you may wish to purchase a complete set of PowerPoint slides and the computerized test banks (in MicroTest format) with solutions. These presentations are suitable for teaching corrosion courses at different levels (from undergraduate to postgraduate) and durations (from 6 hrs to 40 hrs). These ready-to-use corrosion PowerPoint slides contain high quality color photographs, illustrations, animations and video clips. They can also be easily edited and customized to your own styles. The corrosion test banks contain over 1,000 corrosion questions for your use in tutorials, tests or examinations. These questions are conveniently grouped into 4 categories in the test bank: (1) true or false, (2) multiple choice, (3) calculation, and (4) reasoning and open-ended discussions).
