PROJECT MOTIVATION AND DRIVERS PROJECT SPECIFICATIONS TRL 4

PROJECT MOTIVATION AND DRIVERS Utilization of Best Available Technologies (BAT) > This leads to reduction of SO 2 from the asset’s vented gas (150 mg/Nm 3 ) > Can be applied in existing assets > Examples of assets include Habshan 1 & 2 Fostering Innovation across ADNOC through the development of own technologies > 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 Tackling the Upcoming Challenges of Tomorrow > No mandate exists in the UAE to achieve very low levels of SO 2 emissions. > UAE is a signatory on the COP mandate which will create more ambitious future targets > Anticipation of government mandate to reduce SO 2 emissions from existing assets

APPROACH AND TECHNOLOGIES USED TECHNOLOGY ASSUMPTIONS TGTU TECHNOLOGY Low Solvent $20 Pressure $4 Used Steam Per ton Per kg Stainless Steel MOC Carbon Steel TSA TECHNOLOGY Heated Mixed Air Oxide $15 600 o C Adsorbent Per kg INCOLOY MOC

APPROACH AND TECHNOLOGIES USED COMMON ASSUMPTIONS Electricity 100% Water Cost Cost Capacity ($0.005/KG) ($0.03/kWh) Factor (8760 h) Fuel Gas Cost 30 Year Plant Life ($2.62/MMBtu) Lang Factor of 6 13

STANDARD OPERATIONAL COMPARISON TGTU Cost TSA Cost ($18/ton Sulphur) ($12/ton Sulphur) 200 PPM 0 PPM Anticipated Return / Saving ($):  $94.5MM estimate for CAPEX of TGTU  $49.5MM estimate for CAPEX of TSA > $1.855MM annual OPEX estimated for TGTU 14 14 > $1.63MM annual OPEX estimated for TSA

TECHNOLOGY LIMIT COMPARISON TGTU Cost TSA Cost ($24/ton Sulphur) ($12/ton Sulphur) 5 PPM 0 PPM Anticipated Return / Saving ($): > $106.8MM estimate for CAPEX of TGTU  $49.5MM estimate for CAPEX of TSA > $2.48MM annual OPEX estimated for TGTU 15 15 15 15 > $1.63MM annual OPEX estimated for TSA

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