Key messages Extensive testing provides confidence in Phase 2B works to significantly improve plant performance ➢ Understanding of the Orbost Gas Processing Plant (OGPP) has greatly improved throughout 2021 ➢ Recent performance and average gas processing rates have improved: ─ H1 FY21: 23 TJ/day ─ H
Slide 4: Snapshot of Phase 2B works
Snapshot of Phase 2B works Phase 2B approved by Cooper Energy will complete works agreed under the Transition Agreement • Phase 2 works were agreed in accordance with the Transition Agreement signed with APA in 20201 ─ Phase 2A involved reconfiguration of absorbers to enable parallel and / or indepe
Slide 5: A recap: extracting H2S from Sole raw gas
A recap: extracting H2S from Sole raw gas Process utilises technology under licence from Shell Treated gas to sales pipeline • Sole gas contains H2S (~1,000 ppm1) which requires <4 ppm H2S extraction • Technology uses naturally occurring bacteria to convert H2S into solid sulphur Process solution re
Slide 6: The objective: keep absorbers clean to optimise performance
The objective: keep absorbers clean to optimise performance Each absorber proven to operate at 34 TJ/day when clean OGPP processing rates and Sole GSA volumes: 1 January 2021 to 18 August 2021 TJ/day 70 60 50 45 TJ/day Cleaning of each absorber every two weeks Ave: 40 TJ/day (i.e. one absorber clean
Slide 7: Phase 2B filters: solids removal package
Phase 2B filters: solids removal package Designed to remove sulphur solids before solution re-enters the absorbers Treated gas to sales pipeline • The package consists of multiple individual filter cartridges <4 ppm H2S Backwash cycle Solid that cycle between filter mode and backwash mode sulphur se
Slide 8: Phase 2B filters: successful trials at OGPP
Phase 2B filters: successful trials at OGPP Absorber simulations confirm ability to remove solids Fouling of absorber Absorber packing Foaming simulation using existing packing with with filtered solution OGPP process solution1 unfiltered solution Packing clear of Solid sulphur build- solid sulphur
Slide 9: Phase 2B spray nozzles
Phase 2B spray nozzles Designed to reduce foaming within the absorbers which may reduce fouling • Process solution sprayed through nozzles at the top of each absorber. • Spray expected to supress foaming within the absorbers and may also have a positive effect on fouling • Sulphur particles have bee
