Supplying turnkey solutions to design, supply and install improved lining systems to meet today’s demands.
The current ethylene market is extremely active in the USA due to the abundance of low cost natural gas. Natural gas is often the process feed and fuel source for ethylene production. The increase in natural gas supply in the USA, and equally dramatic reduction in price, are driving significant growth throughout the industry. Major new expansion and debottlenecking projects are underway, as well as retrofitting of existing units by almost all major producers.
Thorpe has been the leader in ethylene furnace linings since our early 1970’s development of Z-BLOK I™; the first folded, pre-compressed, ceramic fiber module system and many subsequent derivative products and solutions. Thorpe actively participates in maintenance and retrofit opportunities with ethylene furnace owner/operators as well as capital projects with furnace licensors and mechanical contractors. Through our extensive maintenance work in these units, we are familiar with the operational and reliability issues relating to furnace refractory linings. By combining our engineering capabilities and skilled field crews, we routinely supply turnkey solutions to design, manufacture, supply and install improved lining systems to meet today’s demands. These demands include better operational efficiency and improved thermal and mechanical reliability and performance.
Some customer problems we have solved include:
Brick lining instability due to inferior anchor systems
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 zones
Solving tramp air intrusion with HOTSEAL® Furnace Penetration Seals
Peephole surrounds cracking and spalling
Peepdoor plugs falling off
Overall high shell temperatures
Improved radiant heat distribution
Application of Emisshield® High Emissivity Coating installations
