Industrial Waste Conversion

Can your refractory help you meet environmental directives while still safely and efficiently converting industrial, chemical or hazardous waste?

Saint-Gobain provides full-furnace refractory capabilities to meet local environmental directives and cost-effective waste conversion goals. Saint-Gobain produces refractory linings that can withstand long exposure to fluctuating heat loads, hot acids and process gases.

Chromia-alumina bricks, castables and special shapes offer outstanding corrosion resistance

Refractory bricks, shapes and castables from Saint-Gobain offer outstanding corrosion resistance and oxidation resistance at high temperatures. Saint-Gobain is recognized worldwide for the development of high-performance refractories.

The company’s excellent shape making capability ensures a more precise refractory lining installation. These special shapes  provide a better fit for reduced maintenance and downtime over the lifetime of your equipment. 

Refractory selection depends on whether the waste material is solid/viscous or liquid/gaseous.

Solid/Viscous Waste Incineration: Rotary kilns are used and require high abrasion resistance while resisting corrosive atmospheres at high temperatures. Various refractories may be selected for various zones in the furnace. In high wear areas, Chromcor® BDAK alumina-chromia material is recommended. For the overall lining, mullite-based materials, such as MS4, are used.

Liquid/Gaseous Waste Incineration: Liquid or gaseous waste from chemical processes is mostly incinerated on site. Saint-Gobain has a range of refractory systems suitable for the most corrosive environments, including chlorides, fluorides, PCB and organochlorides. Fluoride-containing waste is very aggressive to silica, even at low temperatures. Coral® FP monolithic, a phosphate bonded ramming monolithic, is a proven material for this specific application, whereas MS2R mullite bricks are recommended for alkali-containing residues.
