Abstract

Natural gas dehydration is a crucial process in the energy industry, ensuring pipeline quality gas that meets stringent specifications for transmission and distribution. This research examines key technologies employed in natural gas dehydration, including glycol absorption, desiccant adsorption, solvent salt adsorption, chemical cooling, and hydrate suppression. Among these, glycol absorption remains the most widely used method, particularly in large-scale gas processing operations. However, it faces significant challenges such as emissions, glycol losses, and degradation, particularly in Nigeria's gas fields and storage facilities, impacting operational efficiency and environmental compliance. Desiccant adsorption offers high dehydration efficiency, achieving very low water dew points, but requires effective regeneration strategies and is often limited to specific applications due to cost and complexity. Other methods like solvent salt adsorption, chemical cooling, and hydrate suppression have niche applications but are less prevalent for mainstream gas dehydration. This study focuses on optimizing glycol absorption systems, addressing prevalent issues, and proposing practical solutions to enhance gas processing performance. It details the technology's process flow, operational challenges, and potential fixes for improving dehydration efficiency, reducing emissions, and minimizing losses. Key aspects like glycol circulation rates, regeneration systems, and contamination management are analyzed to provide a comprehensive understanding of the process.

Abstract

  Boosting carbon capture in coal-fired power plants is crucial for achieving greener energy and mitigating climate change . Pinch analysis, a systematic optimization technique, enhances carbon capture efficiency by minimizing energy consumption and reducing environmental impact. In coal plants, achieving high-purity CO₂ capture is a key objective. Using a 30% MEA (monoethanolamine) solution for carbon capture introduces an initial energy premium of 17.6%. However, applying pinch assessment techniques results in a significant 12.3% reduction in overall energy consumption. This translates to a substantial 50% decrease in energy requirements for carbon capture operations. The implementation of pinch analysis enables coal-fired power plants to achieve an impressive 90% CO₂ capture efficiency, underscoring the potential of this approach to enhance sustainability and cost-effectiveness. By optimizing heat exchange networks and identifying optimal heat transfer points, pinch analysis reduces energy and water consumption in carbon capture processes. This systematic optimization contributes to operational efficiency improvements, paving the way for greener and more sustainable power generation practices. The use of pinch assessment techniques offers a pathway towards cleaner energy production, reduced environmental footprints, and compliance with global climate goals . By strategically matching hot and cold streams, coal plants can minimize resource usage while boosting carbon capture performance.
