The proliferation of biobased-renewable fuel industries was driven by the depletion of the finite fossil fuel reserves and the rising consciousness on sustainable and environmental consequences. Hence, the present study aims to establish baseline economics for a two-stage anaerobic system by performing a comprehensive analysis using a set of assumptions for what can plausibly be achieved within a twenty-year timeframe. The techno-economic analysis was carried out to elucidate the viability of the proposed anaerobic system that produces biohydrogen (BioH2), and biomethane (BioCH4) from locally generated palm oil mill effluent (POME). Process modelling and economic analyses were performed using a modelling software SuperPro Designer. The plant conditions were temperature at 50 °C for both stages, and HRT of 1 and 10 days for BioH2 and BioCH4, respectively. The economic profitability assessment demonstrated the feasibility of the project with the dynamic payback period (DPP), return on investment (ROI), internal rate of return (IRR), and net present value (NPV) of 8.01 years, 19.87%, 21.48% and USD 4,624,705, respectively. Furthermore, the economics of this system was most sensitive to POME quality and product selling prices. The results revealed that a two-stage anaerobic system might both expand the production of renewable energy and enable improved productivity and revenue of palm oil mills to move forward cleaner production industry.

两级厌氧系统从棕榈油厂废水中生产生物氢和生物甲烷的技术经济分析

生物基可再生燃料行业的蓬勃发展是由于有限的化石燃料储备的枯竭以及人们对可持续性和环境后果的意识日益增强。因此,本研究旨在通过使用一系列假设对二十年时间范围内可能实现的目标进行全面分析,从而为两阶段厌氧系统建立基线经济学。进行了技术经济分析,以阐明拟议的产生生物氢(BioH 2)和生物甲烷(BioCH 4)的厌氧系统的可行性。)来自本地产生的棕榈油厂废水(POME)。使用建模软件SuperPro Designer进行过程建模和经济分析。两个阶段的工厂条件均为50°C,BioH 2和BioCH 4的HRT分别为1天和10天。经济效益评估通过动态投资回收期(DPP),投资回报率ROI),内部收益率(IRR)和净现值(NPV)证明了该项目的可行性。)(8.01年),分别为19.87%,21.48%和4,624,705美元。此外,该系统的经济性对POME的质量和产品售价最敏感。结果表明,两阶段厌氧系统既可以扩大可再生能源的生产,又可以提高棕榈油厂的生产率和收入,从而推动清洁生产产业的发展。
