This systematic literature review critically examines the processes, contaminant profiles, and hydrate inhibition efficacy of regenerated Monoethylene Glycol (MEG) in the oil and gas industry. The analysis highlights the multifaceted challenges posed by various contaminants, thermal degradation, and the need for precise contaminant management to maintain MEG’s effectiveness. Key findings include the significant impact of contaminants such as acetic acid, sodium chloride, and calcium carbonate on MEG performance, and the necessity of considering thermal history in MEG application. The review also identifies critical research gaps, including the need for systematic studies on individual contaminants, optimization of contaminant concentrations, and exploration of diverse gas mixtures. Addressing these gaps will enhance the reliability and efficiency of MEG in hydrate inhibition, contributing to more sustainable operational practices in the industry.
