چکیده مقاله
Purpose: This study aims to reduce solvent vapor pollution in printing units by applying Zeolite Type 3A for water adsorption and ethyl acetate separation The focus is on minimizing VOC emissions and improving industrial air quality The proposed approach offers a sustainable alternative to conventional solvent disposal methods Methods: Zeolite was selected for its porous structure and selective pore size for water adsorption Thermodynamic data confirmed exothermic and spontaneous adsorption ΔH = 45 kJ/mol, ΔG = 13 8 kJ/mol After drying, ethyl acetate was separated in a tray column with 98% purity Results: Zeolite effectively removed water vapor without adsorbing ethyl acetate, enhancing product purity Adsorption data fit the Langmuir isotherm with high accuracy R² > 0 99 Regeneration at 150°C demonstrated strong cyclic stability Conclusion: Using zeolite reduced pollutant emissions and improved process efficiency Compared to other methods, zeolite showed superior selectivity and thermal resistance This technology is industrially viable and compliant with environmental regulations
