HWI has been a refractory technology leader in the gasification industry since 1974. We are a member of the American Petroleum Intitute (API Refractory Products Group) and support both slagging and non-slagging gasifiers around the world. Our gasifier solutions serve the chemical, incineration, power generation, and the refineries and petrochemical industries.

We know the costs involved when units are offline, so our materials promote the fastest possible dry-out schedules to get our customers’ units back online. And as refractory service conditions become harsher, HWI can identify likely failure mechanisms at play via postmortem and chemical analysis. Understanding these mechanisms provides critical information to determine which refractory products are a custom fit.

We are constantly researching, adapting, and supporting new customer processes. Our goal is to be ready with products that meet your changing needs. Our dedicated application specialists, engineers, and research and development team will build custom solutions, troubleshoot issues, and recommend changes to optimize customer operations.

AUREX® 95 P Brick Is a Leading Choice for Commercial Gasifiers

In 2009 the US Department of Energy (DOE) published ratings for the AUREX® 95 P, giving it an “‘excellent’ or ‘exceptional’ in terms of increasing service life in high-wear areas of the gasifier, and in lowering operational costs.” In that same article, the DOE went on to say, “The AUREX® 95 P represents the most significant improvement in gasifier refractories in over 25 years”.
