Last Result and next challenge

1. The 5,000-hour-operation using IHI advanced system

completed by the end of Mar. 2017.

Stable Operation at high CO2 absorbing efficiency for Long Term

Period can be performed.

2. Observed heat stable salts formation rate in ISOL-162 was

considerably less than that of MEA.

ISOL-162 have a potential to reduce the deterioration of Amine

solvent.

3. Significant reduction in amine emission was observed in

specific wash process conditions.

More environmental friendly process can be proposed.

Wash Type 1 and Wash Type 2 allow to reduce the

Amine emission significantly.

With further development from Wash Type 2 to Wash

Type 4, the emission could be reduced to

approximately one fifth.

5. Summary & Conclusions

Through the long term stable operation at PICA pilot plant with the

project team(IHI, CSIRO and AGL Loy Yang) in Loy Yang A Power

Station, Australia in 2017-2019, we have developed as follows,

1. ISOL-162α(2018) can decrease solvent deterioration other than

former ISOL-162.

2. Various Wash types are evaluated and then Wash Type 4 can

reduce the amine emission significantly.
