植物油脂的广泛应用和利用使其年产量大幅度增加。脂肪和油主要作为食品和动物饲料、化学工业的原材料以及最近作为生物燃料生产的原材料消费。本文对微生物油脂生化生产的经济性进行了研究，并首次对微生物油脂的生命周期进行了评价。使用商业模拟器模拟生产过程，以执行准确的物料和能量平衡，并从公开文献中收集所有必要的数据。在工艺模拟步骤之后，进行详细的技术经济分析，并估计每年生产2至40 kt微生物油的固定资本投资。在完成技术经济分析后，进行生命周期清单分析，并使用综合生命周期评估方法估计环境影响。
The widespread application and utilization of vegetable oils and fats has led to a significant increase of their annual production. Fats and oils are mainly consumed as food and as animal feed, as raw material in the chemical industry and more recently as raw material for biofuel production. In this work the economics of the biochemical production of microbial oil is investigated and the life cycle assessment is performed for first time in the open literature. The production process is simulated using commercial simulators to perform accurate material and energy balances and all necessary data are collected from the open literature. Following the process simulation step a detailed technoeconomic analysis is performed and the fixed capital investment is estimated for a production that varies from 2 to 40 kt of microbial oil per year. Having completed the technoeconomic analysis the Life Cycle Inventory Analysis is performed, and the environmental impacts are estimated, using the comprehensive Life Cycle Assessment methodology.
