Abstract
The Moomba Gas Plant in northeast South Australia processes natural gas produced from the Cooper Basin. CO2 in the natural gas is separated and has historically been vented to atmosphere. The Moomba Carbon Capture and Storage (CCS) Project aims to reduce these greenhouse gas emissions from the Moomba Gas Plant by 1.7 Mtpa CO2-e starting from 2024. The CO2 will be captured, processed and transported by pipeline to the depleted Strzelecki and Marabooka Gas Fields where it will be permanently stored. Designing a CCS system is similar to traditional hydrocarbon systems but there are important differences due to the nature of CO2. This paper discusses some of the key considerations in the design and integration of the capture, processing, transport and storage systems for the Moomba CCS Project. The composition of the CO2 stream, including minor impurities and water content, is a major factor that affects all systems. The phase behaviour of CO2 and the associated low temperatures are also important, particularly when injecting into low-pressure storage reservoirs.
Keywords: carbon capture and storage, CCS, CO2, composition, compressor, Cooper Basin, design, flow assurance, injection well, low-pressure, Moomba, pipeline.
Phillip Lemon is a Development Engineer working for Santos Ltd. He joined Santos in 2010 and has since worked in a variety of roles, mainly in reservoir and production engineering. In the Energy Solutions team he has been focused on opportunities to reduce Santos’ carbon emissions, initially CO2 enhanced oil recovery and then carbon capture and storage. Most recently he has worked on the Moomba CCS and Bayu-Undan CCS Projects. Phillip graduated from the University of Adelaide in 2009 with a BEng (Hons) in Petroleum and Mechanical Engineering. He is a member of SPE and EA. |
