RTI International and Casale SA Announce Global Licensing and Cooperation Agreement for RTI’s Breakthrough Warm-Gas Desulfurization Process Technology
RESEARCH TRIANGLE PARK, NC- Today, Casale SA and RTI International announced the signing of a global licensing and cooperation agreement that grants Casale the rights to be the exclusive sublicensor for RTI’s breakthrough warm gas desulfurization process technology that produces cleaner energy and chemicals from coal and other high-sulfur feedstocks.
This advanced market-ready technology enables high-sulfur gas streams, such as synthesis gas from coal or petcoke gasification, 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 percent when compared to conventional cleanup technologies.
This technology uses a novel transport reactor design and a unique high capacity, regenerable, attrition-resistant sorbent with excellent performance. This technology can achieve up to 99.9 percent removal of total sulfur from syngas at temperatures as high as 650°C and over a wide range of sulfur concentrations and operating pressures. 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 3,500 hours.
The integration of this technology with a downstream activated-amine carbon capture process enabled further reduction of total sulfur in the syngas to sub-ppmv concentrations (as low as 100 parts per billion), 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 desulfurization 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.”

Another large capacity Chinese plant will adopt Casale technology
Henan Jindadi ChemicaL Co. Ltd, (China) will build a new 1800 MTD, coal based ammonia plant in Henan province based upon Casale’s synthesis technology and proprietary equipment.
Casale’s scope of work under the contract will comprise, besides license and process design, also the supply of the ammonia converter cartridge and a synlop waste heat boiler capable of producing 3,8 MPa steam.
The boiler will be directly flanged to the converter exit nozzle in fashion typical of Casale design, which ensures reduced cost and superior reliability.
This new contract adds to the 3 large synloops, i.e. higher than 1800 MTD, already won by Casale in the last few years, in testimony of the long term reliability and efficiency of operation of its technology.
Two more new ammonia plants will use Casale technology in China
Casale has been selected by Yihua Fertilizer Company (YFC), one of the leading fertilizer producers in China, to provide ammonia synthesis technology for two new, coal-based ammonia plants.
The first plant, of 1820 MTD capacity, will be built by Hubei Yihua Fertilizer Co., Ltd., a subsidiary of YFC, in a site near the city of Yichang, in Hubei province. The second one will have 1250 MTD capacity and will be built by Yichang Xingxing Bluesky Technology Co., Ltd. also in the vicinity of Yichang City.
Under the deal Casale will provide know-how, process design, ammonia converter internals and site assistance.
“We are happy for this new win, which besides strengthening our company’s market share in China, it contributes to increasing the total fertilizer output and the efficiency of operation of such a prestigious company as Yihua Group” says Mr G. Guarino, CEO of Casale.
