Steam Reformer Furnaces are at the core of many plants used in the production of Ammonia, Methanol, Syngas, Acetic Acid, and refined hydrocarbons.
This critical equipment operates under extreme temperatures and pressures, requiring the use of high alloy materials. These materials are subject to long-term degradation due to stresses caused by fatigue, thermal, creep, and residual issues.
Reformer Tubes, Pigtails, and Collection Headers utilize materials which reside in the creep regime. These components operate at the upper limits of the materials structural properties with which they are manufactured. Plant upsets or extreme operating conditions can adversely effect the continued serviceability of the components.
A design life of 100,000 operating hours has been the normal time-based criteria for considering retirement of tubes. Operators of these furnaces require specific assessments which will ensure continued safe operation and tube reliability to optimize plant performance. The damages created within the furnace require assessment techniques and software that will target specific damage mechanisms that result from operation of this equipment.
