Sulfur stripped from sulfur fumes in other units of the sulfur acid plant is routed through the sulfur reaction unit to be converted to elemental sulfur. The main purpose of the reaction furnace is to burn part of the feed at temperatures up to 2800°F. Gases then pass through a series of converters and condensers that convert the gases to elemental sulfur and condense them to liquid. All process units operating over 500°F must use refractory linings to maintain steel-shell stability.

HarbisonWalker International provides several excellent solutions for hot-face linings in sulfur reaction units. These products are all available in hundreds of different shapes to effectively meet your needs.

UFALA®, a dense 60 percent alumina, low-alkali-impurity firebrick, is ideal for refractory linings operating up to 2600°F. It resists hydrogen sulfide gas and provides a highly reliable brick lining.

KORUNDAL XD® is a dense, 90 percent alumina-mullite bonded brick refractory. It resists hydrogen sulfide gas operating at temperatures over 2800°F.
