Abstract:Furfural has been selected as one of the top 30 biomass derived platform compounds by the U.S.Department of Energy based on several indicators including the raw material used for production, estimated processing cost, technical complexity, and market potential. In this work, several high value chemicals such as butadiene, surfactants, jet-fuels and lubricants are produced from furfural. The paper proposes the integrated flowsheet to produce those chemical and techno-economic and life cycle analysis is performe… Show more
“…Multiple thermodynamic models can be used in Aspen Plus's process simulation, and the proper selection and correct use of the thermodynamic model determine the accuracy, reliability, and success of the simulation. NRTL thermodynamic package is selected for the property method to predict the liquid-liquid and liquid-vapor behavior [21] . Next, heat integration is carried out using Aspen Energy Analyzer V8.8 to generate the optimal heat exchanger network designs.…”

The need for producing renewable fuels from biomass has increased due to depleting fossil resources and environmental concerns. However, the low fraction of biomass carbon converted to product is an undeniable drawback for most current biofuel productions from fermentation due to undecomposed lignin in biomass composition and carbon loss as CO 2 . In this work, two main production routes of the MixAlco® process, the Ketonization route (KR) and Esteri cation route (ER) are evaluated for the mixed alcohol production by brown algae, third-generation biomass without lignin. A Novel Fermentation process using syntrophic bacteria consortia (SBC) is developed to produce acetic acid from waste gas produced by KR and ER process. The paper investigates the integrated owsheet for these alternative routes, using techno-economic and life cycle analysis to compare the minimum selling price and environmental impacts. The ER's capital and operating cost combined with the SBC is the highest compared with other routes. The cost of raw materials and utilities are the two major cost factors for all the processing routes examined. ER process performs the best in terms of environmental impacts except in water depletion compared with other processes, while the KR process performs the worst regarding the environmental metrics.

“…In the bioenergy sector, concepts such as oxycombustion of biomass for nearly zero‐net emissions , pressurized anaerobic digestion and biogas upgrading , and techno‐economic assessment of biomass‐based chemical production have been investigated using Aspen Plus. Even though each study handles the modeling process from a different technological perspective, the main goal is the development of a realistic process model with high efficiency and product quality.…”
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.
