This study assesses the techno-economic feasibility of an integrated biorefinery based on pineapple processing waste. Xylooligosaccharides, ethanol, xylitol, bromelain, and silage are among the key products of the biorefinery. The economic performance of the processes involved in generating the biorefinery products was assessed based on calculations performed in ASPEN Plus. Seven different scenarios were designed with individual and multiple products and were further evaluated for a plant capacity of 10 tons per hour as the base case. Sensitivity analysis showed that plant capacity and selling price of value-added products were the most important factors that influenced plant economics. The plant capacity twice the base capacity often made the venture economically feasible as in the case of scenarios 1 (production of xylitol and silage) and 7 (production of bromelain, xylitol, and silage) with an NPV of $9.2 million and $8.9 million, respectively. Increasing the selling price of the products by 25% of the base case made scenarios 1 and 6 (production of bromelain, xylitol, ethanol, and silage) economically viable (NPV > 0). A decrease in the price for procurement of pineapple waste from $25/ton to $10/ton made scenario 4 (production of bromelain and silage) profitable with an NPV of $3.3 million and IRR of 42%.

综合菠萝加工废弃物生物精炼厂的工艺设计和技术经济可行性分析

本研究评估了基于菠萝加工废料的综合生物精炼厂的技术经济可行性。低聚木糖、乙醇、木糖醇、菠萝蛋白酶和青贮饲料是生物精炼厂的主要产品。根据在 ASPEN Plus 中执行的计算，评估了生产生物精炼产品所涉及的过程的经济绩效。针对单个和多个产品设计了七种不同的场景，并以每小时 10 吨的工厂产能作为基本案例进行了进一步评估。敏感性分析表明，工厂产能和增值产品销售价格是影响工厂经济性的最重要因素。工厂产能是基础产能的两倍，这通常使企业在经济上可行，如情景 1（生产木糖醇和青贮饲料）和情景 7（生产菠萝蛋白酶、木糖醇和青贮饲料），NPV 分别为 920 万美元和 890 万美元. 将产品售价提高 25% 的基本情况使方案 1 和 6（菠萝蛋白酶、木糖醇、乙醇和青贮饲料的生产）在经济上可行（NPV > 0）。菠萝废料的采购价格从 25 美元/吨降至 10 美元/吨，使情景 4（菠萝蛋白酶和青贮饲料的生产）盈利，NPV 为 330 万美元，内部收益率为 42%。木糖醇、乙醇和青贮饲料）经济可行（NPV > 0）。菠萝废料的采购价格从 25 美元/吨降至 10 美元/吨，使情景 4（菠萝蛋白酶和青贮饲料的生产）盈利，NPV 为 330 万美元，内部收益率为 42%。木糖醇、乙醇和青贮饲料）经济可行（NPV > 0）。菠萝废料的采购价格从 25 美元/吨降至 10 美元/吨，使情景 4（菠萝蛋白酶和青贮饲料的生产）盈利，NPV 为 330 万美元，内部收益率为 42%。
