“…Peng Robinson with Boston Mathias mixing rules (PR-BM) is used in calculating the product yields from the SCWG reactor. It has been reported that PR-BM property method produced the closest value with the experimental data [68] and employed in other SCWG modelling studies [68][67] [69]. The feedstock stream (20,000 kg/h) contained 5 wt% wheat straw (1000 kg biomass/h) [70].…”

Aspen Plus has become one of the most common process simulation tools for both academia and industrial applications. In the last decade, the number of the papers on Aspen Plus modeling of biomass gasification has significantly increased. This review focuses on recent developments and studies on modeling biomass gasification in Aspen Plus including key aspects such as tar formation and model validation. Accordingly, challenges in modeling due to specific assumptions and limitations will be highlighted to provide a useful basis for researchers and end‐users for further process modeling of biomass gasification in Aspen Plus.

“…Moreover, experimental analysis and process simulation are often applied to make up for the lack of data by many scholars. A pilot scale experiment and process simulation by Aspen Plus for sewage sludge treatment by supercritical water gasification (SCWG) were conducted to explore the features of the emerging technology. A novel technique route for methanol from sludge based on gasification technology was developed and analyzed by Aspen .…”

In this paper, a decision-making framework based on process simulation and the fuzzy PROMETHEE II method was proposed to evaluate the performances of the waste management alternatives considering the situation of lacking data and uncertainty. Process simulation and fuzzy multi-criteria decisionmaking methods were applied to deal with the problem of insufficient data and uncertain information from linguistic descriptions. First, a criteria system covering environmental, economic, technical, and social aspects was established for sustainability evaluation. Then, sustainability assessment was conducted based on the results of process simulation. The fuzzy best−worst method was applied to obtain the fuzzy weights for the criteria based on the preferences of stakeholders, and the fuzzy PROMETHEE II approach was presented to generate the ranking for all the alternatives. A case study for the prioritization of sludge-to-energy technologies was carried out to demonstrate the feasibility of the proposed framework. Sensitivity analysis and uncertainty analysis were also conducted to verify the stability and robustness of the model. Results indicate the effectiveness of the proposed model on providing reference for the waste-to-energy alternatives ranking and giving constructive suggestions for the industry and future research directions. The constructed model can not only provide useful references for decision-makers but also can inspire researchers to investigate biomass management technologies in a similar framework, and the application may even extend to other fields.
