Ceramic Coatings for Petrochemical Refineries and Hydrocarbon Processing
ITC Coatings manufactures high-temperature ceramic coatings that protect refractory linings, boiler tubes, heat exchangers, and process vessels in petrochemical refineries and hydrocarbon processing facilities. Our coatings reflect up to 98% of radiant heat, extend refractory and metal component life 2–5x, and protect against the corrosive, erosive, and high-temperature conditions found throughout refinery operations.
The Problem: Extreme Conditions in Petrochemical Processing
Petrochemical refineries and hydrocarbon processing plants operate some of the most demanding thermal and chemical environments in industry. Fluid catalytic cracking units (FCCUs) cycle catalysts at temperatures exceeding 1,300°F. Sulfur recovery units handle highly corrosive H₂S and SO₂. Fired heaters and reformers sustain tube temperatures above 1,600°F for continuous operation. These conditions create:
• Accelerated refractory degradation from thermal cycling, chemical attack, and catalyst erosion
• Tube failure in fired heaters and reformers from oxidation and carburization
• Corrosion of steel structures in sulfur-containing atmospheres
• Heat loss through degraded insulation systems, increasing fuel consumption
• Unplanned shutdowns during turnarounds costing millions per day in lost production
The Solution: ITC Ceramic Coatings for Petrochemical Applications
ITC coatings address these problems through radiant heat reflection (keeping heat where it belongs — in the process) and surface protection (creating a hard ceramic barrier against chemical attack, erosion, and thermal shock). The result is longer equipment life, lower fuel consumption, and fewer emergency repairs between scheduled turnarounds.
Petrochemical Applications for ITC Coatings
Fluid Catalytic Cracking Units (FCCUs)
ITC 100HT protects refractory linings in FCCU reactors, regenerators, risers, and cyclones from catalyst erosion and thermal cycling. The ceramic coating hardens the refractory surface, reducing erosion rates from circulating catalyst and extending reline intervals. ITC 213 protects metal components in the flue gas system from high-temperature oxidation and sulfidation.
Sulfur Recovery Units (SRUs)
Sulfur recovery operations expose refractory and metal to H₂S, SO₂, and elemental sulfur at elevated temperatures. ITC coatings create a chemical barrier that resists sulfur compound attack on both refractory linings (ITC 100HT) and metal surfaces (ITC 213). This extends component life in Claus reactors, thermal reactors, and waste heat boilers.
Fired Heaters and Process Furnaces
ITC 100HT on the refractory lining of fired heaters reflects radiant heat back toward the process tubes, improving thermal efficiency and reducing fuel consumption. The coating also protects refractory from flame impingement damage, thermal shock during startups and shutdowns, and chemical attack from combustion products. Fuel savings of 10–30% have been documented in comparable furnace applications across industries.
Boilers and Heat Recovery
ITC 213 on boiler tubes, economizer surfaces, and heat recovery equipment protects against high-temperature oxidation, acid dew point corrosion from sulfur-bearing flue gases, and erosion from flyash and particulate. The full ITC three-product system (213 + 100HT + 296A) provides comprehensive protection for steel structures exposed to corrosive exhaust environments.
Carbon Black Units
Carbon black reactors operate at extreme temperatures with highly erosive carbon particulate. ITC 100HT on refractory surfaces resists erosion while reflecting heat back into the reactor, improving yield and extending refractory campaigns.
Reformers
ITC 100HT on the refractory lining of steam methane reformers and catalytic reformers reflects radiant heat toward the catalyst tubes, improving heat transfer efficiency and reducing firing rates. This translates directly to fuel savings and lower operating costs.
Why Petrochemical Facilities Choose ITC
Turnaround efficiency: ITC coatings are spray-applied during scheduled turnarounds and cure in place during heat-up. No additional downtime required.
Proven fuel savings: 10–30% fuel reduction documented across comparable furnace and kiln applications, with savings measured in hundreds of thousands to over a million dollars per year.
Extended refractory life: 2–5x longer refractory campaigns mean fewer relines, less refractory waste, and more production time between turnarounds.
Corrosion protection: ITC 213 has been independently tested against alkali chloride and sulphate corrosion at 900°C, with every steel grade tested showing improvement. NACE-standard sour gas testing showed zero iron oxide after 90 days at 486 PSI.
Zero VOCs: ITC coatings are environmentally safe with no volatile organic compounds — important for refineries managing air quality permits and emissions compliance.

Frequently Asked Questions: ITC in Petrochemical
Can ITC coatings be applied during a turnaround?
Yes. ITC coatings are spray-applied and dry quickly, making them ideal for turnaround schedules. The coatings cure in place during the normal unit heat-up — no separate curing process is needed, so no additional downtime is required beyond the planned turnaround window.
How do ITC coatings reduce fuel consumption in fired heaters?
ITC 100HT on the refractory lining reflects up to 98% of radiant heat back toward the process tubes instead of allowing it to pass through the refractory and escape through the furnace shell. This means more of the fired energy reaches the process fluid, reducing the amount of fuel needed to maintain the target process temperature.
Can ITC coatings withstand FCCU catalyst erosion?
Yes. ITC 100HT creates a hard ceramic surface on the refractory that resists erosion from circulating catalyst particles. The coating hardens the refractory surface layer, reducing the rate of material loss from abrasive catalyst contact.
Are ITC coatings compatible with refinery emissions requirements?
Yes. ITC coatings contain zero VOCs and are environmentally safe. They produce no hazardous emissions during application or service, supporting refinery air quality permits and environmental compliance programs.
