Sulfur Furnace High Emissivity Coating: 5% Fuel Savings in LaPorte, Texas
| Industry | Hydrocarbon & Chemical |
|---|---|
| Asset | Sulfur furnace (dense castable) |
| Customer or location | LaPorte, Texas, USA |
| Products used | Emisshield refractory coating |
| Headline metric | 5% fuel savings |
| Secondary metric | Lower shell temperature |
| Also measured | Reduced maintenance |
A natural-gas sulfur furnace in LaPorte, Texas, with a four-year-old hard refractory lining, was sprayed with Emisshield on its dense castable walls. Fuel demand dropped 5%, thermal response across the reaction zones improved, carbon emissions and exterior shell temperature fell, and refractory life extended with lower maintenance.
01
What was the challenge?
The operator wanted overall thermal improvement and reduced maintenance on a furnace running at roughly 980°C on natural gas with an aging castable lining.
02
What was applied?
Emisshield sprayed onto the dense castable refractory walls.
03
What were the results?
| Metric | Before | After |
|---|---|---|
| Fuel consumption | Baseline | −5% |
| Thermal response | Baseline | Markedly improved |
| Exterior shell temperature | Baseline | Significantly reduced |
| Carbon emissions | Baseline | Declined |
| Refractory life and maintenance | Baseline | Extended; reduced |
04
Why did it work?
The coated castable re-radiates burner energy into the reaction zones rather than reflecting it, stabilizing heat distribution and lowering the energy lost through the shell. See Energy Savings.
