The Tassie Shoal Methanol and LNG Projects have the benefit of being centrally located with access to a shallow water site with benign sea conditions, allowing for the placement of low cost modularised infrastructure to process raw gas from the surrounding discovered but undeveloped gas fields.
The Tassie Shoal Methanol Project ("TSMP") combines established proven technology in an innovative way to produce methanol from high CO2 feedstock gas. By designing for high CO2 in the feedgas stream, TSMP avoids the need for expensive separation, transportation and geo-sequestration costs in alternative LNG or domestic sales gas development scenarios.
The TSMP design marries proven technologies of a concrete gravity structure with topsides processing based on Davy Process Technology Steam Methane Reforming (SMR) technology.
The Tassie Shoal site is located adjacent to many discovered but undeveloped high CO2 gas resources in the region. For each TSMP, feedgas of ~200 million standard cubic feet per day (Mscfd) is required, depending upon CO2 content, to enable the production of 5000 tonnes per day (1.75million tonnes per annum) of high quality methanol. Methanol is a chemical building block with numerous industrial application as well as being increasingly used in energy related applications, such as a direct fuel or as an additive to gasoline to produce a high-octane, efficient fuel with lower emissions than conventional gasoline. Methanol gasoline blends have widespread use in China and other countries and is also emerging as a clean fuel for the shipping industry, providing the opportunity for the industry to meet increasingly stringent environmental requirements.
