The project will assess the novel Piperazine (PZ) process for coal fired power station flue gas, particularly for Australian conditions. Research will include the assessment of the energy requirement for liquid absorbent regeneration, as determined by a newly developed flash regeneration system, and the CO2-absorption rates. This will be compared to energy requirements determined for the standard solvent (30% MEA). The project will seek to establish the stability of the Piperazine solvent, the formation of degradation products from prolonged operation of the process, and the impact on power-generation efficiency and costs of a typical Australian coal fired power station equipped with this technology. In doing so, the aim will be to progress the development of a process that can significantly reduce operating and capital costs by up to 50%, and to provide invaluable information for the scale up and operation of this process.
