Refractory Asset Protection for Petrochemical & Refining Operations

Fired heaters and process furnaces are the workhorses of every refinery and petrochemical complex — and among your most valuable thermal assets. They represent some of the largest energy costs in the plant and some of the most expensive maintenance events when refractory fails. A fired heater reline during a turnaround can cost millions in labor, materials, and extended downtime. Between turnarounds, degrading refractory means declining efficiency, higher fuel bills, and the risk of tube damage from uneven heat distribution.

ITC ceramic refractory coatings deliver comprehensive asset protection — shielding your fired heater refractory, improving radiant heat transfer to process tubes, and reducing the energy penalty of aging linings to keep your critical assets running efficiently between turnarounds.

How ITC Coatings Improve Fired Heater Performance

In a typical fired heater, burner flames and hot flue gases emit radiant energy that strikes the refractory walls. Conventional refractory absorbs and conducts much of this energy through the furnace wall — wasting it as shell heat loss. The remaining energy is reflected, but often at wavelengths that pass through the flue gas without being absorbed by the process tubes.

ITC 100HT changes this equation. The coated refractory surface reflects up to 98% of radiant heat back toward the process tubes. This means more of each BTU fired reaches the process fluid, less heat escapes through the shell, and the refractory operates at a lower through-thickness temperature — extending its service life.

Applications in Petrochemical & Refining

Crude & Vacuum Heaters — Coat radiant section refractory to improve heat transfer to process tubes, reduce bridgewall temperatures, and cut fuel gas consumption. Documented savings of 5–15% depending on heater configuration.
Catalytic Reformer Heaters — Improve temperature uniformity across the tube bank to reduce hot spots that accelerate coking and shorten catalyst life.
Steam Methane Reformers (SMR) — Protect refractory in the radiant box and improve heat transfer efficiency. Reduce NOx emissions through lower excess air requirements.
Ethylene Cracking Furnaces — Coat radiant coils and refractory to improve thermal efficiency and reduce coking rates in high-severity operations.
Thermal Oxidizers & Incinerators — Protect refractory linings from corrosive flue gases in waste treatment and emissions control systems.
Boilers & Steam Generators — Improve heat transfer and protect refractory in high-pressure boiler fireboxes and superheater sections.

Asset Protection That Fits Your Turnaround Schedule

ITC 100HT can be applied during a planned turnaround as part of the refractory maintenance scope. Application is fast — brush, spray, or trowel — and the coating cures during the normal controlled heat-up sequence. No additional downtime is required beyond what's already scheduled for refractory inspection and repair.

For plants looking to extend the interval between turnarounds, ITC's asset protection coating reduces the rate of refractory degradation that forces early shutdowns. The protective ceramic barrier resists erosion from high-velocity flue gases, chemical attack from sulfur-bearing fuels, and thermal cycling damage from load swings — keeping your refractory assets in service longer.

ITC vs. High-Emissivity Coatings

Many petrochemical operators are familiar with high-emissivity coatings that absorb and re-radiate heat. ITC 100HT takes a different approach: radiant heat reflection. Rather than absorbing energy and re-emitting it (which still heats the refractory), ITC reflects energy directly back toward the process tubes without thermally loading the lining. The result is both improved heat transfer and superior refractory protection — benefits that pure emissivity coatings often trade off against each other.

With a maximum service temperature of 5,000°F — well above the 3,100°F ceiling of competing coatings — ITC 100HT provides margin for process upsets, flame impingement events, and high-severity operations where other coatings fail.
