Summary: Vinasse, a residue from the distillation of fermented juice for ethanol production, can be used as a feedstock for biomethane production by reducing sulfate concentrations and increasing organic matter concentration through the use of ultrafiltration membranes. Digestion experiments showed that the ultrafiltration concentrate had the highest biomethane production rate, while the ultrafiltration permeate had the lowest biomethane production rate.

Summary: Few studies have been conducted on sludge blankets in treatment systems. This research aimed to analyze the sludge blankets of three UASB reactors used in sugarcane vinasse treatment. Changes in granulometry, heavy metal concentration, and organic and inorganic contents in the sludge blanket were studied. Results showed a reduction in granular diameter and an increase in metal accumulation, which did not negatively affect the methanogenic process.

Summary: The experiment used a mixed-UASB reactor to treat baker's yeast wastewater, showing that an increase in inlet wastewater concentration led to higher removal of organic compounds, but lower methane production efficiency. Chemical oxygen demand efficiency ranged from 9.05% to 35.98% at concentrations of 1.55 to 4.1 mg COD cm(-3). At the end of 40 days, the volume of biogas obtained from the wastewater was 113.4 L.

Summary: This study aimed to energetically valorize sludge from wastewater treatment plants and discharges from the wine sector through anaerobic co-digestion. Two different processes, single-stage mesophilic anaerobic digestion and Temperature-Phased Anaerobic Digestion (TPAD), were employed for the valorization. Biodegradability tests were conducted to determine the methane production yield, and the results showed that the single-stage process was more effective in methane generation compared to the TPAD process.

Summary: The treatment of sugarcane vinasse is a challenge in sustainable bioethanol production, with anaerobic digestion being the most promising method. This study investigated the dynamics of microbial communities in a 100m(3) UASB methanogenic reactor during bioethanol production. Firmicutes were found to play a specific role in vinasse treatment, and the adaptation of inoculum to vinasse influenced microbiota diversity. The microbial community structure adapted to changes in feed and persisted during starvation periods in the reactor.

Summary: This study conducted a techno-economic analysis comparing two types of thermophilic anaerobic reactors and three biogas utilization schemes. The results showed that the Fixed Bed Reactor (FBR) produced twice as much biogas as the Continuous Stirred Tank Reactor (CSTR) under the same conditions. The economic analysis indicated that co-firing in existing boilers by fuel-oil replacement and partial substitution of coal was more economically attractive than electricity production at the current electricity pricing in Indonesia.

Summary: Further studies are needed to improve the stability and efficiency of methane production from vinasse. Anaerobic digestion with one or more wastes and the addition of micronutrients, especially iron, are attractive operational strategies for this purpose. The performance of two treatment systems, consisting of UASB reactors operated under mesophilic and thermophilic temperature conditions, was evaluated for the anaerobic digestion of vinasse. The addition of water treatment plant (WTP) sludge in ADVS promoted the recovery of the reactors and increased methane production and stability, regardless of the system and proportion of WTP sludge used.

Summary: Non-conventional amines are being researched worldwide to overcome the limitations of traditional amines like MEA and MDEA. Adequate process and thermodynamic models are crucial for understanding the applicability and performance of these amines in CO2 absorption, but studies on process modeling for these amines are limited. This study used rate-based modeling and Deshmukh-Mather method to model CO2 absorption by DETA solution in a packed column, validated the model with experimental data, and conducted a sensitivity analysis of mass transfer correlations. The study also compared the CO2 absorption efficiency of DETA solution with an ionic solvent [bmim]-[PF6] and highlighted the importance of finding optimum operational parameters for maximum absorption efficiency.

Summary: The utilization of smart water in EOR operations has gained attention, but more research is needed to understand the complex mechanisms involved. This study investigated the interfacial tension between smart water and crude oil, considering factors such as salt, pH, asphaltene type, and aged smart water. The results revealed that the hydration of ions in smart water plays a key role in its efficacy, with acidic and basic asphaltene acting as intrinsic surfactants. The pH also influenced the interfacial tension, and the aged smart water's interaction with crude oil depended on asphaltene type, salt, and salinity.

Summary: In this study, high-performance solid catalysts based on phosphotungstic acid (HPW) supported on Zr-SBA-15 were synthesized and evaluated for the one-pot conversion of furfural (FUR) to γ-valerolactone (GVL). The catalysts were characterized using various techniques, and the ratio of HPW and Zr was found to significantly affect the selectivity of GVL. The HPW/Zr-SBA-15 (2-4-15) catalyst exhibited the highest GVL yield (83%) under optimized reaction conditions, and it was determined that a balance between Bronsted acid sites (BAS) and Lewis acid sites (LAS) was crucial for achieving higher catalytic performance.
