There is serious concern about the projected levels of carbon dioxide in our atmosphere; yet, at the same time, a large and growing appetite for cheap electrical power generated from fossil fuels. hence technologies are being developed to capture and sequester the carbon dioxide (a) sketch and describe the concept of 'post-combustion capture', including a specification of which gases must be separated identify three different options for geological sequestration in the australian context and explain which of these is deemed to have the greatest storage capacity (b) the most extensively developed technology (to date) for co2 emissions capture from power stations is based on absorption. identify a typical solvent, explain the process chemistry of the absorption process and describe some of the key process issues that need to be improved (c)
