“…Aspen Plus is one of the process simulators used commercially to investigate problems related to the application of the PSE tools in petrochemical, chemical, and industrial processes. The main characteristics of this commercial simulator are (i) its up‐to‐date and complete databanks, which makes it powerful and appropriate for simulation related to electrolytes as well as solid non‐conventional materials such as biomass and coal and (ii) the availability of several thermodynamic properties and models and complete unit operations representations 5 . One of its differentials is the possibility of integration of an interface and bidirectional platform, allowing the simulation of non‐linear models typical of fermentation/biorefinery processes 6 .…”

Fermentation is the main process for converting substrates into bioproducts such as ethanol, bioplastics, and different foods and drinks. However, there are numerous challenges associated with the fermentation process in bioreactors and many of them can be solved using simulations based on process systems engineering (PSE). This study's objective is the design and assessment of the applicability of simulations of three fermentation processes (alcoholic, lactic, and propanoic) through their kinetic parameters, using the commercial process system engineering platform Aspen Plus, integrated with a chemical kinetics subroutine made as a Fortran User Model for calculating the process balances. The simulations of fermentation models in Aspen Plus were consistent, considering the experimental models available in the literature. In most cases, the residual standard deviation (RSD) (%) obtained was below 10%, which is acceptable for biotechnological processes. Some cases did not represent the literature models due to the limitations of the simulator (thermodynamics and components), linked with the complexity of the model. The applicability of these models within a commercial simulator, although limited, is therefore valid for the design, analysis, and optimization of complex reactional systems, such as fermentation, which implies quick technological advances, especially regarding bioprocesses.

“…Silica (SiO 2 ) is an essential material that is mostly used for applications such as adsorbents (chemical or moisture), glasses, catalyst supports, buildings and construction, pharmaceuticals, medicine, and electronics. [1][2][3][4] However, silica production still relies on non-renewable raw materials (sandstone) and fossil fuels. [5,6] On the other hand, several crops can naturally convert mono-silicic acid from the soil to silica by the oxolation process.…”

“…[21][22][23][24] The ash content in bamboo leaves accounts for 25.86 wt.%, with silica content in the ash surpassing 90 wt.%. [2,11,18] Those properties are higher than rice husk, with 16.1 wt.% of ash content which on average contains $90 wt.% silica. [25,26] Compared to sugarcane bagasse, bamboo leaves also have more significant properties: sugarcane bagasse has only 4.14 wt.% of ash content and up to 88.7 wt.% of silica content in the ash.…”

The fallen yellowish bamboo leaves around bamboo crops are always overlooked even though they contain high silica in their ash. Bamboo leaf valorization consequently has the potential to be a green process for synthesizing amorphous silica. Unfortunately, the optimum process parameters have not been widely disclosed. Hence, this study intends to optimize the synthesis of amorphous bio‐silica nanoparticles from bamboo leaves using Box–Behnken design (BBD). Bamboo leaves were initially washed with HCl, followed by combustion at 700°C, and then ash washing, extraction of silica with NaOH (sol–gel method), gelation, and drying. According to the results, optimum conditions occur under no acid washing of leaves, solvent‐to‐feed ratio = 5 mL/g, and extraction duration = 1.5 h. The optimum conditions give the highest purity (94.1 wt.%) and yield (42.33%) as well as the highest surface area (328.61 m2/g), smallest pore diameter (8.69 nm), and largest pore volume (0.71 cc/g) of bio‐silica nanoparticles. Furthermore, bio‐silica nanoparticles are amorphous, spherical‐shaped aggregates, and have a white powdered colour.

“…Recently, the use of biomass attracts many researchers' attention due to its sustainability and contribution to a low carbon footprint. [1][2][3][4][5][6][7][8] Rice husk, as agricultural biomass, has high heating value (2870-4067 kcal/kg) and high volatile matter (55% to 60%), so it is attractive to be exploited as fossil fuels substitute. 9,10 The green products from rice husk are mostly obtained through combustion.…”

The knowledge of fluid–particle flow behavior is necessary. Unfortunately, computational fluid dynamics (CFD) studies are mostly focused on developing numerical methods in detail. Instead, the CFD studies should also subtly shift to become a tool for digitalizing fluid science to guide the practical industrial aspects. Therefore, this simulation study intends to reveal the air and rice husk flow behaviors in a vertical suspension furnace, complete with presenting digital simulation data, aiming to alleviate the escape particle amount. According to this study, the escaped particle amount was suppressed under more sphere particle, smaller particle size, and feed inlet pipe that sunk into the burner. The properties change from rice husk to ash, along with temperature escalation (as in combustion phenomena), enlarging the escaped particle amount, so the cyclone should be installed to handle it. In addition, the results of digital turbulent data from CFD simulation have succeeded in intriguing and revealing the fluid–particle flow behavior in the vertical suspension furnace. The data show a close match to the real phenomena occurring inside this furnace which reflects the standard k–ε model can conclusively predict fluid–particle flow behavior without conflicting Newton's second law of particle motion.
