Clariant to supply sorbent for warm gas desulfurization technology to RTI
MUNICH — Clariant announced the signing of a global licensing agreement with RTI International granting Clariant exclusive rights of supply for their solid sorbent material, which is vital for RTI’s warm gas desulfurization process (WDP) technology.

WDP is an advanced market-ready technology for producing cleaner energy and chemicals from coal and other high-sulfur feedstocks. It enables sulfur-containing gas streams, such as synthesis gas (or syngas) from coal or petcoke gasification, to be cleaned at elevated temperatures (250°C–650°C), thus reducing or eliminating the need for substantial gas cooling and expensive heat recovery. This increases overall process efficiency, reduces greenhouse gas emissions, and reduces the capital and operating costs of the entire gas cleanup block by up to 50% compared to conventional technologies.
A solid fluidizable sorbent to be supplied by Clariant is key to the WDP technology due to its unique characteristics. Able to function across a wide range of operating temperatures and pressures, the quick-reacting sorbent has a high capacity for adsorbing sulfur, removing H2S and COS to very low levels and allowing customers to treat large gas streams volumes. The sorbent is regenerable with a low attrition rate and long cycle lengths without major replacement requirements, thus reducing the need for shut-downs.
WDP technology can achieve up to 99.9% removal of total sulfur from syngas at temperatures as high as 650°C and over a wide range of sulfur concentrations. The process was demonstrated, with funding support from the US Department of Energy, on a 54,000 Nm3/h synthesis gas stream in a coal/petcoke gasification plant at Tampa Electric’s Polk Power Station in Florida, where it operated successfully for more than 3,500 hr.
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.
Clariant is a supplier of catalysts and sorbents used in the synthesis gas, or syngas, process industry, with a long history of innovation and expertise in the field. Clariant has already produced more than 100 t of sorbent in commercial-scale equipment for use in RTI’s scale-up and near-commercial demonstration testing of the WDP technology.
In the business of hydrocarbon production, accurate accounting of produced fluids and gases is critical from a process control, management and fiscal perspective.
The US East Coast will send out its first LNG exports in early 2018 as Dominion Energy’s Cove Point LNG export facility in Lusby, Maryland becomes operational.
The New LNG Imperative
The shale gas boom established the US as the world’s leading natural gas producer and is responsible for billions of dollars of investments in the US gas processing industry. Since 2012, the US has witnessed unprecedented growth in new gas processing capacity and infrastructure. This rise is due to greater production of domestic shale gas, which is providing cheap, available feedstock to fuel the domestic gas processing, LNG and petrochemical industries. New gas processing projects include the construction of billions of cubic feet per day of new cryogenic and gas processing capacity, NGL fractionators, multi-billion-dollar pipeline infrastructure projects, and the development of millions of tons per year of new LNG export terminal construction.
