Dynamic Modeling of a High Temperature CO2-Rich Giant Gas Field with a Carbon Capture and Storage Strategy

Abstract Carbon Capture and Storage (CCS) technologies are a perspective solution to reduce the amount of CO2 emissions. One of promising methods is Ca-looping, which is based on carbonation and calcination reactions. During both of these processes, especially calcination, high temperatures (650-950°C) are required. This means high demands on the corrosion resistance of equipment materials. Therefore, we carried out a study to suggest materials with suitable properties for calciner construction, which have to be particularly heat resistant: stainless steels (AISI 304, AISI 316L and AISI 316Ti) and nickel alloys (Inconel 713, Inconel 738, Incoloy 800H). A special device simulating calciner environment was built for this purpose. Chosen materials were tested in temperature 900°C, atmospheric pressure and gaseous environment with composition that can be possible in a calciner. The surfaces of materials were evaluated to determine composition and properties of formed oxide layers. High temperature oxidation was observed on all tested materials and oxide exfoliation occurred on some of tested materials (304, 316L).

The CO2CRC has a demonstration storage project underway in the Otway Basin of southwest Victoria. The aim of the project is to demonstrate that carbon capture and storage (CCS) can be performed under Australian conditions. The project involves extracting CO2 rich gas from an existing field and injecting it into a nearby depleted natural gas field for long-term storage. Injection commenced in April 2008, and approximately 100,000 tonnes of CO2 are planned to be injected through a new injection well drilled in 2007. A multi-disciplinary monitoring and verification (M&V) program has been in place from late 2005 and a baseline state of the subsurface, near surface and atmospheric conditions has been comprehensively defined prior to the commencement of injection. The project has also been instrumental in unravelling the legislative overlaps between jurisdictions and has helped shape the regulatory regime being developed by the Victorian Government. At the present time over 35,000 tonnes of CO2 has been injected and a variety of monitoring data collected. This paper aims to provide an update on the holistic project and how some of the findings may lead to expediting commercial uptake of CCS in Australia.

Growing concern on global warming directly related to CO2 emissions is steering the implementation of carbon capture and storage (CCS). With Malaysia having an estimated 37 Tscfd (Trillion standard cubic feet) of natural gas remains undeveloped in CO2 containing natural gas fields, there is a need to assess the viability of CCS implementation. This study performs a techno-economic analysis for CCS at an offshore natural gas field in Malaysia. The framework includes a gas field model, revenue model, and cost model. A techno-economic spreadsheet consisting of Net Present Value (NPV), Payback Period (PBP), and Internal Rate of Return (IRR) is developed over the gas field’s production life of 15 years for four distinctive CO2 capture technologies, which are membrane, chemical absorption, physical absorption, and cryogenics. Results predict that physical absorption solvent (Selexol) as CO2 capture technology is most feasible with IRR of 15% and PBP of 7.94 years. The output from the techno-economic model and associated risks of the CCS project are quantified by employing sensitivity analysis (SA), which indicated that the project NPV is exceptionally sensitive to gas price. On this basis, the economic performance of the project is reliant on revenues from gas sales, which is dictated by gas market price uncertainties.
