Casale SA and RTI International have announced the signing of a global licensing and cooperation agreement that grants Casale the rights to be the exclusive sublicensor for RTI’s warm gas desulphurisation process technology.
This advanced market-ready technology enables high-sulphur gas streams to be cleaned at elevated temperatures (250-650°C), thus reducing or eliminating the need for substantial gas cooling and expensive heat recovery systems. This increases the overall process efficiency, reduces greenhouse gas emissions, and also reduces the capital and operating costs of the entire gas cleanup block by as much as 50% when compared to conventional cleanup technologies.
Removal of up to 99.9% of total sulphur from syngas at temperatures as high as 650°C is possible. The process was demonstrated on a 60 000 Nm3/h synthesis gas stream in a coal/petcoke gasification plant at Tampa Electric’s Polk Power Plant in Florida, where it operated successfully for more than 3500 hours.
The integration of this technology with a downstream activated-amine carbon capture process enabled further reduction of total sulphur in the syngas to sub-ppmv concentrations (as low as 100 ppb), suitable for stringent synthesis gas applications such as chemicals, fertilizers, and fuels.
“RTI has been developing this technology over a number of years with support from the U.S. Department of Energy and we are enthusiastic that our testing of the technology through pre-commercial scale was completed so successfully and that the technology is now ready for commercial deployment,” said Raghubir Gupta, Ph.D., Global Head, Energy Technology Division at RTI. “We are very excited that Casale, a technically strong global leader in syngas conversion technologies, will be our partner in taking this technology into the global marketplace.”
“Casale already has a strong presence in fertilizer and methanol plants based on gasification, where we are a leader in the supply of sour gas shift and synthesis technologies,” said Ermanno Filippi, Ph.D., Chief Technology Officer of Casale. “This agreement allows us to further expand our offering in these plants in the field of synthesis gas cleaning and conditioning, and to offer the warm gas desulphurisation process for IGCC (integrated gasification combined cycle) and other gasification-based units. This agreement builds upon a very successful longstanding relationship between Casale and RTI.”
