Hydrocarbon and Chemical Processing
Application Information: Emisshield Products were applied to Incoloy process tubes, the hard refractory sidewalls and ceramic fiber roof
Emisshield® Benefits:
- Energy Savings of 5%
- Production Increase of 6%
- Reduced coking – doubled time between decoking cycles
- Coke was powdery and much easier to remove than typical coke
- Improved cracking reaction / conversion
- Improved thermal response of furnace
- Reduced air emissions
- Decreased thermal stress and oxidation on process tubes
- Significant reduction in outside furnace skin temperature
