Biorefineries offer a promising alternative to fossil-based processing industries and have undergone rapid development in recent years. Limited financial resources and stringent company budgets necessitate quick capital estimation of pioneering biorefinery projects at the early stages of their conception to screen process alternatives, decide on project viability, and allocate resources to the most promising cases. Biorefineries are capital-intensive projects that involve state-of-the-art technologies for which there is no prior experience or sufficient historical data. This work reviews existing rapid cost estimation practices, which can be used by researchers with no previous cost estimating experience. It also comprises a comparative study of six cost methods on three well-documented biorefinery processes to evaluate their accuracy and precision. The results illustrate discrepancies among the methods because their extrapolation on biorefinery data often violates inherent assumptions. This study recommends the most appropriate rapid cost methods and urges the development of an improved early-stage capital cost estimation tool suitable for biorefinery processes.
生物精炼厂为基于化石的加工行业提供了一种很有前景的替代方案，并且近年来经历了快速发展。有限的财政资源和严格的公司预算使得在开创性生物精炼厂项目构思的早期阶段就需要快速进行资本估算，以便筛选工艺替代方案、确定项目可行性，并将资源分配到最有前景的项目中。生物精炼厂是资本密集型项目，涉及尚无先前经验或足够历史数据的先进技术。这项工作回顾了现有的快速成本估算方法，没有成本估算经验的研究人员也可以使用这些方法。它还包括对三种有详细记录的生物精炼工艺的六种成本估算方法进行比较研究，以评估它们的准确性和精确性。结果表明这些方法之间存在差异，因为它们对生物精炼厂数据的推断常常违反固有假设。本研究推荐了最合适的快速成本估算方法，并敦促开发一种适用于生物精炼工艺的改进型早期资本成本估算工具。
