An economic evaluation was conducted of flavanone and sugar production from orange peel (OP) using a sequential hydrothermal process. The process was conducted at laboratory (2 × 5 L), pilot (3 × 10 L), and industrial (3 × 500 L) scales. The results demonstrate that the scale‐up process decreased the cost of manufacturing (COM) with a significant increase in flavanone and sugar production. The lowest COM was of US$ 25.72/kg flavanones and US$ 1.43/kg sugars, both on an industrial scale. The predominant costs at the industrial scale (>90%) were the cost of utilities and the cost of raw materials. A low capital payback time was obtained, which decreased as return on investment and gross margin increased. A strengths, weaknesses, opportunities, and threats matrix demonstrates the relevant business topics related to the scale‐up of OP processing. Thus, the current scale‐up project can be considered as a promising approach to the production of flavanones and sugar from OP on an industrial scale. © 2020 Society of Industrial Chemistry and John Wiley & Sons Ltd

顺序水热法从橙皮生产黄烷酮和糖的经济评价

使用顺序水热法对橙皮（OP）中的黄酮和糖生产进行了经济评估。该过程在实验室（2×5 L），中试（3×10 L）和工业（3×500 L）规模下进行。结果表明，规模扩大的过程降低了制造成本（COM），同时黄酮和糖的产量显着增加。在工业规模上，最低的COM分别为25.72美元/千克黄烷酮和1.43美元/千克糖。工业规模的主要成本（> 90％）是公用事业成本和原材料成本。获得的投资回收期很短，随着投资回报率和毛利率的提高而降低。优势，劣势，机会和威胁矩阵显示了与OP处理放大相关的相关业务主题。因此，当前的扩大规模项目可以认为是从工业规模上以OP生产黄烷酮和糖的有前途的方法。©2020工业化学学会和John Wiley＆Sons Ltd
