High Emissivity Coatings for Hydrocarbon & Chemical Processing

Fired heaters·cracking furnaces·reformers·process tubes·sulfur furnaces·flares

In refining and petrochemicals, fired heaters, crackers, and reformers consume the site's largest fuel share, and uneven heat flux drives coking, hot spots, and early shutdowns. Emisshield raises firebox and tube surfaces to at least 0.96 (M-6) emissivity so more of every BTU reaches the process, with documented fuel savings up to 12%, production gains up to 10%, and decoke intervals extended from months to years. ROI is typically under a year.

Typical ROI

Above roughly 540°C, radiation is the dominant mode of heat transfer in a fired heater, and radiation is governed by the surface. Refractory at ~0.4 emissivity and ceramic fiber at ~0.3 reflect a large share of burner energy back into the flue gas, where it leaves up the stack. The control system compensates by firing harder, which raises peak tube-wall temperatures, accelerates coking, pushes bridge-wall temperatures toward alarm, and shortens the run between decokes.

Emisshield converts those surfaces into re-radiators aimed at the coil. Applied at 2.0 to 5.0 mils to the refractory, fiber, IFB, and burner blocks of the radiant box, and in metal-substrate form to tube exteriors and flare tips, it evens heat flux across the coil so the same duty is met at lower firing. Tube metal temperatures fall, coke lays down more slowly, fiber stops shrinking, and fuel and CO2 per ton come down without touching the burners or the pressure boundary.

Application is planned into a turnaround, typically days per heater by certified crews with standard HVLP spray equipment. Formulations are matched to reducing and oxidizing atmospheres, sulfur service, and sour gas with high H2S, and flare coatings are sintered onto the tip before installation for continuous service in direct flame.

One technology across the fired assets of a refinery, petrochemical complex, or fertilizer plant. Each application below has documented installations; the results table and case studies carry the figures.

  • 01Fired heaters

    Crude, vacuum, coker, and process heaters: radiant box refractory, fiber, and IFB coated for lower firing at the same duty and flatter flux across the coil.

  • 02Ethylene and cracking furnaces

    Radiant walls, ceilings, and fiber modules coated; the most documented petrochemical application, with fuel savings to 12% and cracking rate gains to 10%.

  • 03Ammonia and hydrogen reformers

    Fiber, IFB, burner blocks, and throat refractory coated to bring bridge-wall temperatures below alarm, end fiber shrinkage, and stop throat abrasion.

  • 04Process tubes

    Tube exteriors coated to lower peak tube-wall temperature and slow coke formation, extending decoke intervals from months to years.

  • 05Sulfur furnaces

    Dense castable walls coated for fuel savings, better thermal response across the reaction zones, and lower shell temperature.

  • 06Flares and flare tips

    Stainless tips and shells sintered with flare coatings for lower metal temperature, better combustion uniformity, and multiplied tip life in sour-gas service.

  • 07Ceramic fiber and IFB linings

    Coated fiber holds shrinkage under 1%, tolerates continuous duty roughly 150°C higher, and resists gas-velocity erosion.

FAQ

Common Questions From Refining and Petrochemical Engineers

Can Emisshield extend run length between decokes?

Yes. Lower and more uniform tube-wall temperature slows coke formation. The documented process-tube study recorded decoke intervals rising from 9 months to more than 30.

Will it survive our atmosphere?

Formulations are matched to reducing and oxidizing atmospheres, sulfur service, and sour gas with high H2S. Flare coatings run continuously in that environment.

When is it applied?

During planned turnarounds, typically days per heater by certified crews using standard HVLP spray equipment.

Does it affect tube metallurgy?

No. The coating is applied to refractory and fiber surfaces and, in metal-substrate form, to the tube exterior. It adds radiant performance without altering the pressure boundary.
