Full turnkey engineered lining systems on retrofit and capital projects.
Hydrogen, ammonia and methanol production facilities generally utilize a reforming furnace as a key component of the process. These units have similar configurations including a steam methane reformer (SMR), collection ducts, convection sections, transfer lines, and, in some instances, a secondary reformer. Many of the existing units were built 20, 30 or even 40 years ago; eras with different operational requirements and less demand for efficiency or environmental controls compared to today. Some were built before many current-day products and insulation systems were even developed. Customers routinely maintain these units by repairing linings in-kind. This practice allows problems to reoccur and results in missed opportunities to improve performance and reliability.
Thorpe routinely performs refractory maintenance work in these facilities. On retrofit and capital projects, we provide full turnkey engineered refractory lining systems including the design, manufacture or supply, and the installation. We are knowledgeable about operational and reliability issues relating to refractory linings. We include the latest material and engineering technology in our lining designs. This results in improved reliability and reduced maintenance demands in the future. SMRs are usually configured as either a multi-row or Terrace-Wall™ (proprietary Foster Wheeler design) layout. While both of these layouts have design features that bring their own set of refractory problems, they have certain issues in common.
Brick lining instability due to inferior anchor systems
Cracked and spalled castable
Backup lining deterioration leading to high shell temperature
Floor refractory failure requiring high maintenance
Tramp air intrusion lowering efficiency & increasing NOx
