A review of the various literature data for large-scale algae production costs is described. Costs were updated and recomputed in order to compare the different schemes. Total production costs of a nonprocessed biomass range from US$0.15 to US$4.0 kg(-1), according to various authors. Process performance hypotheses and proposed technologies are analyzed to explain these variations. A cost analysis for a tubular bioreactor system is then presented that shows that, assuming a productivity of 60 tons/ha yr, production costs would range from FF24 to FF29 kg(-1) for such a system. Operating costs as well as fixed charges account for approximately 50% of the cost. Parametric sensitivity of these costs is then analyzed: If productivity would be 30, 45, or 90 tons/ha yr, total cost would be around FF48, FF33 and FF19 kg(-1). Advantages and disadvantages of the proposed tubular technology are finally discussed.
对大规模藻类生产成本的各种文献数据进行了回顾。为了进行比较，对成本进行了更新和重新计算。根据不同的作者，未经加工的生物质的总生产成本范围为每公斤 0.15 美元至 4.0 美元。对工艺性能假设和提出的技术进行了分析，以解释这些变化。然后提出了一种管式生物反应器系统的成本分析，结果表明，假设生产率为 60 吨/公顷年，该系统的生产成本将在 FF24 至 FF29 公斤之间。运行成本和固定费用约占成本的 50%。然后分析了这些成本的参数敏感性：如果生产率为 30、45 或 90 吨/公顷年，总成本将约为 FF48、FF33 和 FF19 公斤。最后讨论了所提出的管式技术的优缺点。
