Capital cost is frequently estimated for new and retrofit carbon capture plants as new concepts for cost reduction emerge. Capital cost during initial cost estimation of chemical plants strongly depends on the installation factor(s) of the methodology employed. How these installation factors respond to the cost of each equipment determines the total plant cost and the type of capital cost (new plant or modification project) each method is suited for. The effect of equipment installation factors on capital cost of an amine-based CO2 capture plant using the Enhanced Detailed Factor (EDF) method has been studied. Plant construction characteristic factors have also been introduced to account for different plant construction characteristic situations. The impacts of the installation factors of seven methodologies on capital cost were compared. A uniform installation factor will likely lead to overestimation of very expensive equipment and underestimation of less expensive equipment. EDF method's installation factors respond based on each equipment cost. Even though all the methods estimated the optimum in the cross-exchanger to be 15°C, the cost estimated was €66/tCO2 by the EDF method, Smith's percentage of delivered-equipment factorial method and Hand's factorial method; and €69–79/tCO2 by the other methods. The results demonstrate that the EDF method is suitable for estimating capital cost for new plants and modification projects, small and large plants, and accounts for different plants’ situations.

使用增强型详细系数 (EDF) 方法估算 CO 2捕集设备的资本成本:安装因素和设备建设特征因素
随着降低成本的新概念出现,新的和改造的碳捕集厂的资本成本经常被估算。化工厂初始成本估算期间的资本成本很大程度上取决于所采用方法的安装因素。这些安装因素如何对每个设备的成本做出反应,决定了每种方法适用的总工厂成本和资本成本类型(新工厂或改造项目)。设备安装因素对胺基 CO 2资本成本的影响已经研究了使用增强详细因子 (EDF) 方法的捕集厂。还引入了工厂建设特征因素来说明不同的工厂建设特征情况。比较了七种方法的安装因素对资本成本的影响。统一的安装系数可能会导致高估非常昂贵的设备而低估较便宜的设备。EDF 方法的安装因素根据每个设备成本做出响应。尽管所有的方法都估计了最优在 15°C 的交叉换热器中,通过 EDF 方法、Smith 的交付设备因子方法和 Hand 的因子方法估算的成本为 €66/tCO 2;和 69-79 欧元/吨CO 2其他方法。结果表明,EDF 方法适用于估算新工厂和改造项目、小型和大型工厂的资本成本,并考虑到不同工厂的情况。
