BioSTEAM: The Biorefinery Simulation and Techno-Economic Analysis Modules¶
BioSTEAM is a fast and flexible package for the design, simulation, and techno-economic analysis of biorefineries under uncertainty. BioSTEAM is built to streamline and automate early-stage technology evaluations and to enable rigorous sensitivity and uncertainty analyses. Complete biorefinery configurations are available at the Bioindustrial-Park GitHub repository, BioSTEAM’s premier repository for biorefinery models and results. The long-term growth and maintenance of BioSTEAM is supported through both community-led development and the research institutions invested in BioSTEAM, including the Center for Advanced Bioenergy and Bioproducts Innovation (CABBI). Through its open-source and community-lead platform, BioSTEAM aims to foster communication and transparency within the biorefinery research community for an integrated effort to expedite the evaluation of candidate biofuels and bioproducts.
Key Features & Capabilities¶
Fast and flexible techno-economic analysis. BioSTEAM presents basic building blocks to design and simulate a biorefinery. These include objects that handle material properties, material flows, unit operations, and recycle loops.
Clear representation of streams, unit operations, and recycle systems. Dynamic generation of flowsheets and a clear representation of data allows users to visualize biorefineries in detail. BioSTEAM does not yet have a GUI but we are on our way to building one.
Automated process and technology evaluations. The evaluation of thousands of biorefinery designs is streamlined through smart and efficient management of biorefinery parameters to evaluate sets of design decisions and scenarios.
Complete biorefinery examples. Two complete biorefineries models are included in BioSTEAM: the co-production of ethanol and biodiesel from lipid-cane, and 2nd generation ethanol production from corn stover. Please refer to the tutorial to get started.
The BioSTEAM software has been steadily improved since the original BioSTEAM publication 1. In particular, more rigorous thermodynamic and unit operation models have been implemented, improving the accuracy of the software. In the figures below, the applicability of BioSTEAM is demonstrated in the context of (i) the co-production of biodiesel and ethanol from lipid-cane and (ii) the production of second-generation ethanol from corn stover. All results were generated under uncertainty through Monte Carlo simulations, whereby thousands of biorefinery designs were evaluated across a joint distribution of uncertain parameters. Economic metrics evaluated in BioSTEAM closely match benchmark designs modeled in proprietary software (SuperPro Designer, Aspen Plus). Estimates for the net steam demand and electricity production of the co-heat and power facilities have improved since the original BioSTEAM publication. It is thanks to both community involvement and the institutions supporting BioSTEAM that continuous improvements like these are made possible.
Several studies have leveraged the BioSTEAM platform to compare conversion technologies and chart development pathways for various bioproducts:
