Laser Profilometry Applied To Catalyst Tubes In Reformers For Ongoing Condition Monitoring of Creep DamageNovember/December 1999 Inspectioneering JournalBy Richard D. Roberts at Quest Integrity Group
Steam reformers are an integral part of ammonia, methanol, hydrogen, and gas process plants around the world. THey are one of the highest cost, both in capital and maintenance, pieces of equipment in the plant. Typically, reformers contain several hundred vertically oriented straight tubes, referred to as catalyst tubes. These tubes represent a significant cost for replacement and can be a major source of plant unavailability if unplanned failures occur.

Some owner user answers are included and will be identified as such. In addition to the questions in part 1, I included a listing of some generic families of RBI tools or approaches.

Maintenance planning will now focus on what has the greatest impact rather than what we think is the most important. This will allow formulation of a plan to have some equipment "run to failure" and other equipment to have a "no tolerance" maintenance plan.
