資料簡介

該項目旨在評估在澳大利亞黑煤電站中濃哌嗪（PZ）在燃燒后捕集CO2（PCC）中的使用。濃縮PZ是基于MEA的標(biāo)準(zhǔn)工藝的替代品，根據(jù)廣泛的實驗室研究顯示出有吸引力的特性，使其具有將CO2捕集和壓縮成本降低50％以上的潛力。德州他們的實驗室研究表明：-PZ溶劑比標(biāo)準(zhǔn)溶劑更具反應(yīng)性，這應(yīng)導(dǎo)致吸收器尺寸減小，從而降低資金成本。 -PZ溶劑足夠堅固，可以在高溫下再生，從而導(dǎo)致高壓下釋放CO2，從而降低了壓縮成本。 -溶劑再生的熱能少于MEA。 -溶劑蒸氣壓低于MEA的蒸氣壓，從而降低了溶劑損失。

This project was designed to evaluate the use of concentrated piperazine (PZ) for post-combustion capture of CO2 (PCC) in black-coal fired power stations in Australia. Concentrated PZ is an alternative to the standard MEA-based processes and based on extensive laboratory based research has shown attractive attributes such that they have the potential to reduce the costs of capture and compression of CO2 by more than 50%, according to the University of Texas. Their laboratory research has shown that: - The PZ solvent is more reactive than the standard, that should lead to a reduction in absorber sizes and hence capital cost. - The PZ solvent is robust enough to allow regeneration at high temperature resulting in the release of CO2 at high pressure, thus reducing compression costs. - The thermal energy for solvent regeneration is less than for MEA. - The solvent vapour pressure is lower than that of MEA resulting in lower solvent losses.
