RESEARCH AND DEVELOPMENT AWARENESS R&D APPROACH
PROJECT MOTIVATION AND DRIVERS PROJECT SPECIFICATIONS
TRL 4
> This leads to reduction of SO2 from the asset’s vented gas (150 mg/Nm3) > Can be applied in existing assets > Examples of assets include Habshan 1 & 2 > This leads to the growth of ADNOC and maximization of value. > Developing competitive edge over existing best in class technologies > Examples include SCOT technology currently deployed in Habshan 5 > No mandate exists in the UAE to achieve very low levels of SO2 emissions. > UAE is a signatory on the COP mandate which will create more ambitious future targets > Anticipation of government mandate to reduce SO2 emissions from existing assets
Tackling the Upcoming Challenges of Tomorrow Fostering Innovation across ADNOC through the development of own technologies Utilization of Best Available Technologies (BAT)

CONCLUSIONS AND WAY FORWARD
16
In standard operational mode, the TSA is more advantageous than the TGTU process.
Conclusion 1
At the technology limit, the TSA process is still more advantageous than the TGTU process.
Conclusion 2
The economic advantage of the TSA process is realized when it is used as a
- TGTU. Other configurations can be
explored with further development of the technology.
Way Forward 1
Performance and stability of the adsorbent after pellitization and during adsorption/regeneration to be proven at next stage of development
