“…Moreover, it has a large extensive property databank, including numerous models and stream properties. It also permits the addition of custom blocks through FORTRAN subroutines when advanced, or application-specific modeling is required (Tungalag et al, 2020). A fourstage steady-state equilibrium model by Aspen Plus® was developed by Kabir et al (2015) to simulate pyrolysis of municipal green waste in a rotary kiln.…”

Thermochemical processes, which include pyrolysis, torrefaction, gasification, combustion, and hydrothermal conversions, are perceived to be more efficient in converting waste biomass to energy and value-added products than biochemical processes. From the chemical point of view, thermochemical processes are highly complex and sensitive to numerous physicochemical properties, thus making reactor and process modeling more challenging. Nevertheless, the successful commercialization of these processes is contingent upon optimized reactor and process designs, which can be effectively achieved via modeling and simulation. Models of various scales with numerous simplifying assumptions have been developed for specific applications of thermochemical conversion of waste biomass. However, there is a research gap that needs to be explored to elaborate the scale of applicability, limitations, accuracy, validity, and special features of each model. This review study investigates all above mentioned important aspects and features of the existing models for all established industrial thermochemical conversion processes with emphasis on waste biomass, thus addressing the research gap mentioned above and presenting commercial-scale applicability in terms of reactor designing, process control and optimization, and potential ways to upgrade existing models for higher accuracy.

“…In these studies, the influence of parameters on the characterization of gaseous products is often considered, such as equivalent ratios (ER) (Li et al 2012), temperature, mass ratio of steam to materials, etc. Aspen Plus simulation of municipal solid waste gasification also has been conducted to evaluate the effects of the air equivalence ratio, moisture concentration, and gasifier temperature on the lower heating value (LHV) of syngas, the composition of syngas, heat conversion efficiency, and carbon conversion of municipal solid waste (Chen et al 2010;Niu et al 2013;Chen et al 2013;Begum et al 2014;Deng et al 2019;Tavares et al 2019;Tungalag et al 2020). In short, the role of Aspen Plus software in the pyrolysis and gasification process simulation research has become well established.…”

The disposal of automotive shredder residue (ASR) directly affects China’s goal of achieving a 95% recycling rate for end-of-life vehicles. Pyrolysis and gasification have gradually become the most commonly used thermochemical technologies for ASR recycling. To obtain more hydrogen-rich syngas, it is necessary to determine the optimal process parameters of the ASR pyrolysis and gasification process. The main process parameters of the two-stage ASR pyrolysis and gasification process were studied using the established Aspen Plus model. Through analyzing the effects of process parameters, such as the temperature, equivalence ratio, and mass ratio of steam to ASR feedstock, on the product distribution and product characteristics of ASR pyrolysis and gasification, the optimal process parameters were determined. A series of comparative experiments under different conditions were conducted. The experimental results verified the accuracy and reliability of the Aspen Plus simulation model for the ASR pyrolysis and gasification processes and verified the practical feasibility of the process parameters obtained from the simulation analysis.

“…Generally, simulators are used to investigate the performance of the system before the actual process implementation. ASPEN Plus is one among other simulators which have been used to simulate MSW gasification processes [35] [36] [34]. Begum et al [37] performed a numerical investigation of a fixed bed gasifier for MSW gasification using ASPEN Plus.…”

Municipal solid waste (MSW) is becoming a concern as population in urban area is increasing. Several disposal methods (landfill and biochemical) have been used. However, waste to energy (WTE) particularly gasification technology is a potential technology for energy recovery. The system is used to convert biodegradable material into syngas under limited gasifying media. This study presents numerical analysis of producer gas for the two air paths in the hybrid fixed bed gasifier (HFBG). It was revealed that the optimum operating condition was achieved when the air ratio at the first air flow path (AIR1) was 0.3. Furthermore, the exergy efficiency of about 81.51% was achieved.
