Haldor Topsoe Inc. (HTI) and CoaLogix Inc. have developed a closer collaboration since 2009, which has now been executed into a signed agreement to provide additional value in connection with SCR catalyst supply to the Power generation Industry. HTI will utilize CoaLogix Inc. services exclusively to regenerate spent HTI SCR catalyst to be re-used in the Power industry. HTI will work with its clients to optimize a catalyst loading system including various ratios of HTI

CoaLogix, the leader in SCR regeneration services for power generation is headquartered in Charlotte, North Carolina. CoaLogix has proven that regenerated catalyst has an activity equal to new, and can be available to meet tight schedules. CoaLogix has regenerated over 20,000 modules of catalyst, many during actual plant outages. In addition, CoaLogix has over 40,000 MW under contract for catalyst management services. CoaLogix’ NOxAssure program currently consists of over 3,000 catalyst modules, representing about $30,000,000 of "new value" to coal-fired power plants.

Anders Olsen CEO of HTI commented:" We see this collaboration as a great opportunity to offer our customers another solution to meeting their emission requirements. We are confident that our customers will benefit from lower fill costs while still achieving the desired performance with the optimum mix of fresh and certified regenerated catalyst. Combining the access to certified regenerated catalyst with Topsoe’s detailed knowledge about NOx conversion activity, low SO2 oxidation and the various deactivation mechanisms, enables us to customize optimized loadings for each individual client and specific circumstances."

According to Bill McMahon, CEO of CoaLogix, "Haldor-Topsoe and CoaLogix are working collaboratively with customers to provide more options when they have catalyst upgrades or replacements. Working with a leading catalysis company that has been around since 1940 is a great honor. Collectively, we bring the proven experience, the latest technology and cultures of innovation and services. We will help the power industry’s effort to lower their operating costs while maintaining their emissions compliance. CoaLogix has successfully regenerated more than 2,000 Haldor Topsoe catalyst modules.

Certified Regenerated Catalyst and fresh catalyst to minimize the life cycle cost while maintaining an efficient, trouble free NOx conversion in the plants.
