ABSTRACT
A number of findings from the comparative analysis of gas dehydration techniques are presented. The choice of technique is influenced by a number of parameters, including as the desired dryness level, the type of the gas, cost effectiveness, and environmental impact. Each approach has pros and cons of its own. Absorption is employed when little attention is paid to the output stream's water content and when little cash is needed for operational expenditures. In situations where bone dry NG is necessary, adsorption is employed. While a wealth of literature exists regarding process simulation and parameter optimization for the natural gas dehydration process, very little of it focuses on optimizing the process overall to minimize energy consumption overall, equipment capital and operating costs, carbon emissions, and other environmental factors while imposing restrictions on lean solvent concentration (TEG purity), water removal efficiency (specifications), stripping gas flow, and TEG losses and consumption. There is a need for a more comprehensive strategy.
