Advantages of TIGAR®

1) Lower CAPEX and simple Operation & Maintenance

- Lower pressure and lower temperature in operating condition

- Small air separation unit (oxygen plant)

2) High reliability and availability

- Based on mature fluidized bed technologies

3) Multi-fuel application

- Low rank coal, biomass and their

co-utilization

4) Co-production

- Variable change of ratio of

syngas to power generation

Conclusion

• Twin IHI Gasifier (TIGAR®) can stably produce syngas with higher heating value from Lignite coal.

• As a result of 6t/d Pilot Plant test, TIGAR® is proven technology for lignite gasification.

• CO2 can be captured from syngas using coal gasification, and biomass can be utilized as feed stock easily for CO2 reduction.

• IHI is planning to demonstrate TIGAR® at Indonesian fertilizer plant as first step for commercialization.
