customer needs to narrow focus on gasification work
Gasification process block-wise analysis to narrow down at clean-up process
ChinaCoal accounts for 85% of feedstock for China’s methanol production. In actual terms, more than 3 billion tons of coal are consumed annually.
South Africa South Africa is another promising country for coal to liquids.
IndiaIndia is pushing for Methanol Economy using indigenous coal.
United States and EuropeWith the current shale oil boom in the US and a focus on renewables in Europe, market need of the technologyhas reduced significantly

Technical Details of Warm-Gas Desulphurization Process (WDP)Role of WDP technology
Applications of WDP
Enables high removal of total Sulphur (≥99.9%) from syngas at temperatures as high as 6500C
RTI Proprietary Desulfurization Sorbent Unique highly-dispersed
nanostructures Developed in long-term cooperation
with Clariant (~100 tons to date) Covered by extensive US &
International patents, including several recent improvements
Applicable to both new as well as retrofit systems
Extensive Techno-Economic Analysis (TEA) has been undertaken for WDP.
Customized TEA can be developed as per needs of the customer.

Advantages
Use of Sweet Water Gas Shift (WGS) Reactor in place of Sour WGS Reactor
Easier downstream processing of Sulphur and CO2
