In the pursuit of effective carbon capture technologies, this study presents a novel method for monitoring CO2 absorption in concentrated Monoethanolamine (MEA) solvent systems. Carbon capture is essential for mitigating greenhouse gas emissions, and MEA is a widely used solvent for this purpose. However, real-time and accurate monitoring of CO2 absorption remains a challenge. Here, we introduce a method based on electrical conductivity variations resulting from the interaction between CO2 and MEA. Experimental results demonstrate the feasibility and efficiency of this approach, offering promising prospects for enhanced carbon capture monitoring and process control.

This study investigates the influence of different inoculum types on biogas production efficiency in anaerobic digestion processes. Anaerobic digestion is a crucial technology for renewable energy production and waste management. The efficiency of this process is significantly affected by the type of inoculum used. We evaluated the biogas yield from various inoculums, including cow dung, sewage sludge, and anaerobic digester sludge, using a controlled laboratory setup. Key parameters such as methane content, biogas volume, and the rate of production were monitored and analyzed.

Results demonstrated that the choice of inoculum plays a pivotal role in biogas production efficiency. Cow dung inoculum exhibited the highest biogas yield, followed by anaerobic digester sludge and sewage sludge. Methane content was also significantly higher in biogas produced from cow dung inoculum. The study highlights the importance of selecting an appropriate inoculum to enhance biogas production, providing valuable insights for optimizing anaerobic digestion systems. Future research should focus on the synergistic effects of mixed inoculums and the long-term stability of biogas production. These findings contribute to the advancement of sustainable energy solutions and the effective management of organic waste.
