本文估算了澳大利亚三种工业排放源的二氧化碳捕集成本：钢铁生产、炼油厂和水泥制造业。它还将估计的捕集成本与粉状黑煤发电厂燃烧后捕集的成本进行了比较。2008年使用MEA溶剂吸收技术捕获二氧化碳的成本从钢铁生产避免的每吨二氧化碳不到60澳元到水泥生产避免的每吨二氧化碳超过70澳元，以及炼油厂避免的每吨二氧化碳超过100澳元不等。钢铁和水泥行业的捕集成本与粉状黑煤电厂燃烧后捕集的成本相当或更低。本文还研究了利用加压和水-气变换反应将钢铁生产中的低分压二氧化碳蒸气转化为更集中的蒸气的成本。在这些情况下，发现费用与未换算的费用估计数相似或低于估计数。本文的分析还表明，估算成本高度依赖于工业排放源的特征、与捕获设施使用的能源类型和价格有关的假设以及项目的经济参数，如贴现率和资本成本。(C)2010年CO2CRC Technologies。爱思唯尔有限公司出版。保留所有权利。
This paper estimates the cost of CO2 capture for three Australian industrial emission sources: iron and steel production, oil refineries and cement manufacturing. It also compares the estimated capture costs with those of post-combustion capture from a pulverised black coal power plant. The cost of capture in 2008 using MEA solvent absorption technology ranges from less than A$60 per tonne CO2 avoided for the iron and steel production to over A$70 per tonne CO2 avoided for cement manufacture and over A$100 per tonne CO2 avoided for oil refineries. The costs of capture for the iron and steel and cement industries are comparable to or less than that for post-combustion capture from a pulverised black coal power plant. This paper also investigates costs for converting low partial pressure CO2 streams from iron and steel production to a more concentrated stream using pressurisation and the water-gas shift reaction. In those cases, the costs were found to be similar to or less than the cost estimates without conversion. The analyses in this paper also show that estimated costs are highly dependent on the characteristics of the industrial emission source, the assumptions related to the type and price of energy used by the capture facilities and the economic parameters of the project such as the discount rate and capital costs.
