Mitigating The Risk Of Flow-Accelerated Corrosion

Online course    01-Apr-2021    8:30 am - 3:00 pm MST (Mountain Standard Time)



After participating in this course, you will be able to do the following:

  • Understand the mechanisms of both types of Flow-accelerated Corrosion (FAC)
  • Diagnose FAC in your system
  • Understand how key parameters control the rate of FAC
  • Identify the type of components and areas of the plant that are most susceptible to FAC
  • Mitigate the risk of FAC in the design and operational phases
  • Discover the impact of cycling and part-load operation on the rate of FAC
  • Understand the advantages and limitations of chemical treatment additives in controlling FAC
  • Learn how to mitigate the risk of FAC

Flow-accelerated corrosion (FAC) is regarded as an increasingly common and very insidious type of failure mechanism in steam generation systems across many industries – from power generation to petrochemical. FAC is predominant in Heat Recovery Steam Generators (HRSGs) of combined-cycle and cogeneration plants. The proper management of FAC is of paramount importance since fatal injuries to workers have occurred in several power plants, and hundreds of piping and equipment failures have led to production losses and rising maintenance costs.

There are two types of FAC – single-phase and two-phase FAC, quite different in character and root cause. The troubleshooting of FAC can be complex, and distinguishing between the two types is essential to understanding the issues in contention and to the amelioration of the FAC problem. Many key variables play a role in FAC – mainly system hydrodynamics (system geometry, fluid velocity, steam quality, temperature), materials of construction as well as operating practices. Water or cycle chemistry, however, plays a relatively minor role. All of the above complexities have created confusion and conflicting opinions amongst independent power industry players worldwide.

This course presents several case studies together with Best Practice guidelines that are invaluable to owners and current operators of combined cycle/cogeneration plants as well as those involved in all design phases of such projects, through the potential incorporation of these best practices at the earliest possible stage.

Course Outline:

  • FAC Primer
  • How to diagnose FAC in your system (failure morphology and other leading indicators)
  • Distinguish between the two types of FAC (this is a critical step to understanding and controlling FAC)
  • Learn about the areas and components that are susceptible to FAC attack
  • Understand how key parameters control the rate of FAC (temperature, pH, ORP, fluid turbulence, metallurgy, design and operational factors, etc.)
  • Discover the impact of cycling and part-load operation on the rate of FAC
  • Learn about FAC Management Programs
  • Witness several case studies in industry

Online Courses / Webinars Withdrawal, Cancellation and Rescheduling

By registering for an online training course or webinar organised by Industrial Water Treatment Academy (iwtA) you agree to the following Training Cancellation policy as well to our general Terms and Conditions and Privacy Policy (both available on our website, regardless of whether such registration was made through website or via email, telephone, or any other means.

If you wish to withdraw from an online training event (online course or webinar), you must first advise us by email, and include the official payment receipt.  Our policies regarding refunds are:

  • You may cancel online-based training bookings at any time.
  • If you cancel more than 10 (ten) business days before the training event:  the full amount will be refunded minus a US$75.00 and a US$35.00 administration charge for an online course and webinar, respectively.
  • If you cancel between 3 and 9 business days before the training event: 50% of the full amount paid will be refunded.
  • If you cancel less than 3 (three) business days in advance:  you can request a non-refundable credit, valid for 12 months from the date of the original payment, which can be applied to a different iwtA online course or webinar. Credits are transferable within your company – simply contact the Registrar at with your request giving the name and email address of the co-worker taking your place.
  • If an instructor is not available due to unforeseen circumstances, another instructor of equal ability (decided at the sole discretion of iwtA) will be substituted whenever possible; if a suitable instructor is unavailable, the course will be cancelled and rescheduled. iwtA reserves the right to cancel courses, change instructors, or change course content. If iwtA has to cancel a course due to unforeseen circumstances, a full refund will be issued to the registrant.
  • No training booking will be final and confirmed until the full amount is paid either by credit card or bank transfer.

A Certificate of Completion will be awarded to all participants that attend a given online course or webinar in its entirety.

The Industrial Water Treatment Academy (iwtA) is currently in the initial stages of seeking an ANSI-accredited international standard certification in Continuing Education that will enable iwtA to award Continuing Education Units (CEUs) to its course participants. We expect this milestone to be reached by 2023.
