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.
