The petrochemical industry presents unique refractory challenges — furnaces operate in reducing, hydrogen-rich, and sulfur-bearing atmospheres at temperatures up to 1100°C, while the linings must maintain dimensional stability over long run lengths without shutdowns. Ethylene crackers, steam methane reformers (SMR), naphtha reformers, and fluid catalytic cracking (FCC) units all impose specific material requirements.
Firebrics manufactures dense and lightweight castables, ceramic fiber backup systems, and precision-formed anchor bricks for petrochemical furnace applications. Our products are engineered for low thermal conductivity, excellent creep resistance under sustained loading, and chemical inertness in H₂/CO/H₂S atmospheres. Firebrics supplies petrochemical contractors and EPC firms in the Middle East, Southeast Asia, and South America.
Key Application Zones
Radiant box, convection section, and quench areas — low-iron castables and anchor systems engineered for H₂-rich atmosphere and extreme thermal gradients.
Reformer box lining, tunnel burners, and flue gas manifolds — castables with exceptional hot-strength and resistance to hydrogen embrittlement in reducing conditions.
Claus furnace reaction sections and sulfur condensers require acid-proof, sulfate-resistant castables that maintain integrity in H₂S and SO₂ environments.
Catalyst circulation between reactor and regenerator demands erosion-resistant, impact-resistant castables that survive catalyst particle impingement at high velocity.
