Gasification is one of the most severe processes in the petrochemical industry. Linings must be able to resist high temperatures, high pressure and aggressive atmospheres, as well as aggressive operating parameters.
Saint-Gobain has provided superior refractory lining designs and materials for high-pressure gasifiers for more than 55 years. Exceptional shape-forming capability, dimensional accuracy, quality, consistency, strength and purity are hallmarks of Saint-Gobain materials and design that create refractory linings with superior and reliable service life.
Saint-Gobain also offers refractory installation supervision and technical support for lining inspection and problem solving. Saint-Gobain materials have been tested, validated and approved by all major technology suppliers.
Saint-Gobain manufactures dense and bubble alumina bricks, special shapes, mortars and castables for gasifiers with gas or oil and heavy residues feedstock. AL 100, Alundum® AH 199B and Alundum® AH 199H high alumina bricks are commonly used for the hot face. Their high density and low porosity fit the requirements of ever-changing operating conditions.
In addition to CA334 high alumina castable, Saint-Gobain offers bubble alumina RI 34 or Alundum® AN599 insulating fire bricks or insulating castables CA 333, RI 34 and RI 34 HR.
