Aligning Goals
Government target: Economic Growth and Sustainable Development
Economic Growth requires increased Utilities Services
Increased Utilities Services results traditionally in
increased Emissions, not aligned with
Sustainable Development.
Sargas Technology deliver “Zero Emissions” Utilities Services and
Improved Macro Economy
by:
• Utilization of Low Cost Fuel (Coal) with CO2 and NOx Capturing
• Enhanced Oil Recovery from injection of the captured CO2
• Sale of CO2 quotas under the UN CDM Scheme
Sargas Technology supports the Government’s target
Clean Power Solution s. Now.

• Optimized Heat Recovery
• Integrated Desalination by MED Technology
Performance:
600 Mw PFBC Plant: 584 Mw El.Power, 91 MG/d Water, 16,000 ton CO2/d
Energy Utilization Index: 93%
Sargas Technology gives you Best in Class
Clean Power Solution s. Now.
Cost and Benefits
Economics : Investment 600 MW FBPC plant w/desalination : M$ 1 800.
Cost of CO2 Capture: less than present CO2 quota price < Eur 20 /t.
Pay-back time: 6 to 10 years, dependant on UAE market prices for power, water & CO2
Performance Comparison with Taweela A1
Fuel Efficiency : Sargas
27 % better
Water Efficiency : Sargas
43 % better
Environ. Damage: Sargas
94 % better
Macro Economy : Sargas >1400 % better
Sargas Technology gives you International Recognition!
• Could be the First Large Scale CO2 Capturing Scheme in the World
• Visible Sale of significant CO2 Quotas via International Trading Centers
Sargas Technology is Good Business for all Stakeholders

The Sargas Solution.
Capture of EOR quality CO2 in flue gas from a pressurized combustor.
Cost-efficient, compact and proven process includes NOx reduction to 5ppm.
The Only Commercially Available Solution NOW!
Other Technologies:
Post-combustion once-through CO2 capture.
Low partial pressure of CO2 = high CO2 capture cost.
Requires oxygen sensitive MEA absorbent.
Availability: 2010 to 2015
Post-combustion with partial exhaust recycle (semi-closed).
Higher partial pressure of CO2.
Recycle presents a challenge to the gas turbine. Availability: 2015 to 2020
Pre-combustion de-carbonization (hydrogen plant).
High partial pressure of CO2 at the hydrogen production unit.
Complex system.
Availability: 2015 to 2025
Closed-cycle pure oxygen oxidant (Oxy-fuel).
High partial pressure of CO2; easily captured.
CO2 motive gas requires new turbine.
Availability: 2020 to 2030

Amines



More efficient than other absorbents at atmospheric pressure (Fluor
Econamine, MHI KS-1).
Challenge: Control of corrosion and amine degradation.
Limited references for this application, at least two major amine vendors
remain apprehensive.
Carbonates



Stable, simple process. Oxygen tolerant without solution degradation.
Many relevant references, 90 to 99% CO2 absorption possible with
standard plant design
Requires pressurized system (10 bara+, partial pressure CO2 0.5 bara+)
Amino acids


Old and well known process. Oxygen tolerant, biodegradable.
Not updated/used for this application. A possibility for the future?
Physical absorption


Uhde Morphysorb process: Remaining CO2 loading after solvent
regeneration too high.
Difficult to achieve 90% CO2 absorption.
