MODERN TECHNOLOGIES FOR NATURAL GAS DEHYDRATION AND MOISTURE REMOVAL

Abstract. This thesis examines the technological significance of removing water vapor from natural gas and evaluates modern dehydration methods used in gas treatment and processing plants. The paper discusses glycol absorption, solid-desiccant adsorption, membrane separation, low-temperature condensation, and hybrid systems. Particular attention is given to hydrate prevention, water-dew-point control, solvent and adsorbent regeneration, energy efficiency, process reliability, emissions reduction, and digital monitoring. The analysis shows that no single dehydration method is universally optimal; technology selection must be based on gas composition, pressure, flow rate, required product specification, site conditions, operating flexibility, environmental constraints, and life-cycle cost. Practical recommendations are proposed for improving the reliability and efficiency of natural gas dehydration systems.
