  •    Retrofit technology
  •    Modular design for partial capture
  •    Flexibility in operation to accommodate market conditions
  •    Some processes commercially available
                                Munmorah PCC Pilot Plant
• PCC pilot plant based on aqueous
  ammonia up to 3000 tpa

• Joint Delta / CSIRO Project

• Asia Pacific Partnership Funding

• $7 million construct & operate

• Ammonia solvent – potential multi-
  pollutant scrubber

• Delta will use performance to inform
  technology selection for
  demonstration

What has been achieved

• Capture rates > 90% achieved

• High purity CO2 product (typically > 98.5 %)

• High SO2 removal using ammonia wash water (multi-species scrubbing
  potential confirmed)

What remains
• Evaluate process energy consumption

• Experimental program completion at Munmorah by Aug 2010
