Current domestic ethylene furnace activities primarily involve maintaining existing linings or retrofitting existing units to current state-of-the-art technology. Most new construction is occurring internationally. Thorpe actively participates in the maintenance and retrofit opportunities with ethylene furnace operators as well as capital projects for OEMs. Through our extensive maintenance work in these units, we are familiar with the operation and reliability issues relating to furnace refractory linings. By combining our engineering capabilities and skilled field crews, we routinely supply turnkey solutions to design, supply and install improved lining systems to meet today’s demands. These demands include better operational efficiency and improved thermal and mechanical performance.
Some customer problems we have solved include:
- Hotspots
- Brick lining instability due to inferior anchor systems
- Bullnose failures
- Cracked and spalled castable, particularly in transition sections
- Backup lining deterioration leading to high shell temperature
- Erosion of the lining near burners
- Lining renovation using the Z-BLOK™ Ceramic Fiber Module System
- Floor failure requiring high maintenance
- Decoke nozzles and impact zone
- Solving tramp air intrusion with HOTSEAL™ Furnace Penetration Seals
- Peephole surrounds cracking and spalling
- Peepdoor plugs falling off
- Overall high shell temperatures
- Faster startups/shutdowns
- Improved radiant heat distribution
- Application of Emisshield® High Emissivity Coating installations
Call Thorpe to discuss upgrading your refractory lining system to today’s standards.
