Clariant contributes to the world's first large-scale demonstration of RTI International's warm-syngas clean-up technology at Tampa Electric Company's Polk Power Station


Clariant supplies sulfur removal adsorbent and catalysts for novel warm-syngas cleanup technology
Large-scale application at TECO's Polk County Power Plant will demonstrate the feasibility of future commercial scale-up
The technology results in cost-reduction and efficiency improvements in capturing CO2 and removing contaminants from coal-derived syngas

Munich, May 14, 2014 - Clariant, a world leader in specialty chemicals, is the catalyst partner behind the world's first large-scale demonstration application of RTI International's novel warm-syngas desulfurization process.

RTI International's proprietary warm syngas clean-up technology, which removes contaminants such as sulfur and heavy metals from syngas generated by coal gasification, is being tested on a 50 megawatt-scale pre-commercial demonstration plant at Tampa Electric Company's (TECO) 250-MW IGCC power plant in Polk County, Fla. US Department of Energy's (DOE) Deputy Assistant Secretary for Clean Coal, Dr. Julio Friedmann, participated in the ribbon cutting ceremony for the RTI demo plant on April 9, 2014.

For more than a decade, Clariant has been working with RTI to scale up and supply RTI's proprietary RTI-3 sulfur removal sorbent. Warm-syngas desulfurization lowers the cost of sulfur removal and largely reduces the thermal efficiency penalty compared to conventional low-temperature gas treatment processes. The technology can remove over 99.9 percent of sulfur in the syngas; further reduction can be achieved with polishing steps. The captured sulfur is used to produce sulfuric acid for industrial purposes at the demonstration project site. The project, funded by the US Department of Energy, will also test the large-scale capture of >90 percent of the CO2 from the RTI demonstration facility.

The plant, which will operate through at least June 2015, will demonstrate the feasibility of scaling up the technology to full commercial scale for power or industrial (e.g., chemicals, fertilizers, or fuels) applications. Clariant supplies RTI-3 sorbent and Clariant technology water-gas-shift catalysts for the process from its facility in Louisville, Kentucky.

"The RTI International-led project is the result of the company's 20-year research effort on warm-syngas cleanup technology and we are proud of our contribution as a reliable, value-adding partner. On behalf of Clariant, I would like to congratulate RTI International and TECO on this milestone, which paves the way for improving the efficiency and environmental impact of coal gasification," comments Stefan Heuser, Senior Vice President and Head of Business Unit Catalysts of Clariant.

Vice President for Energy Technology Division at RTI, Raghubir Gupta, says: "We thank Clariant for their continued support of our technology, and we look forward to a successful demonstration that can show the potential of the technology beyond the power sector also for chemical applications".
