“…The project was released in 2007 but abandoned in 2011; it was difficult to continue given a lack of a development roadmap and its use of Python v2.2 (which is no longer supported). OMChemSim is a recently published software written in Open Modelica and is focused on modeling unit operations and mass and energy balances. A key gap, however, is that algorithms for the rigorous design of unit operations as well as economic analyses are not included yet.…”

BioSTEAM, the Biorefinery Simulation and Techno-Economic Analysis Modules, is an open-source steady-state process simulator in Python that enables biorefinery design, simulation, and techno-economic analysis (TEA) under uncertainty through its fast and flexible framework. By incorporating uncertainty as a key feature, BioSTEAM aims to evaluate the landscape of design decisions and scenarios for conceptual and emerging technologies. The applicability of BioSTEAM is demonstrated here 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. Economic metrics evaluated in BioSTEAM closely match benchmark designs modeled in proprietary software (SuperPro Designer, Aspen Plus). Through the automation of unit operation sizing and characterization of utility requirements, process waste streams, and make-up water usage, BioSTEAM also generates data needed for environmental sustainability analyses (e.g., via life cycle assessment). Ultimately, BioSTEAM enables rapid and robust process design, mass and energy balances, and TEA to compare established and early-stage technologies and prioritize research, development, and deployment.

“…This enhances the applicability of the software for a wide range of processes, including bioprocesses. Several studies have reported the application and comparison of DWSIM with other process modeling softwares for chemical processes [15,16]. More recently, Elavazhagan et al [17] have reported the application of DWSIM for the simulation of biodiesel production by transesterification.…”

In the recent times, the application of process simulation software has found its way to the simulation of bioprocesses. Presently, bioprocesses are simulated and technoeconomic analysis is performed in commercially available software for such as SuperPro Designer®, Aspen Plus® etc. These softwares are not freely available and therefore, there exists a need for an open source software for the simulation of bioprocesses. Furthermore, the chemical process softwares show compatibility issues, when used for bioprocesses. More recently, an open source process simulator called DWSIM was introduced for the simulation of chemical processes. However, the applicability and compatibility of DWSIM for complex bioprocess simulation involving microbial biomass has not been reported yet. Therefore, the present study evaluates and reports the simulation results of the bioethanol production process developed by NREL (National Renewable Energy Laboratory, USA), performed in DWSIM. The simulator results were compared to those of existing commercial software, and the results showed good agreement with the literature. This suggests that DWSIM could be a promising alternative for bioprocess flowsheeting and simulation, and further technoeconomic analysis.

“…It was concluded that the performance of the two tools was similar, although some details were lacking in order to make a thorough assessment. Nayak et al [18] compared results obtained with DWSIM, Aspen Plus and a property package implementation in OpenModelica. A few examples involving distillation of water/methanol, ethylene glycol production including distillation of water and glycol/ethylene oxide as well as a conversion reactor (ethanol to ethyl acetate) are shown.…”

In this paper, a detailed evaluation of the open source process simulator DWSIM is presented. Using a previously published simulation model of an oil and gas separation plant, the results obtained with DWSIM are compared to a commercial process simulator widely used in the industry. The modelled flow scheme comprises a vast number of unit operations including separators (flash vessels), valves, splitters, mixers, compressors, heat exchangers, pumps and recycles (tear streams). The results obtained with DWSIM both for characterization of the inlet fluid as well as for a single operating state for the entire process, compare very well with the data obtained using a commercial tool. A rigorous comparison is made and generally, compared results are within 1% in deviation with a few exceptions. Further, an elaborate comparison is made for over 90 simulations with different settings where 10 independent variables are randomly varied over a wide range. Again, good agreement is found between the two tools. The results are very encouraging and provide fidelity in the use of the investigated open source process simulation tools in a professional environment.
