NH3 has attracted increasing attention as a fundamental material and promising hydrogen carrier. The uptake of from NH3-containing exhausted gas presents economic environmental issues. In this study, [MEA][SCN] was paired with glycerol, acetamide, formamide, phenol (PhOH), ethylene glycol, urea, glycerolformal, or 1,3-dimethyl-2-imidazolidinone to construct deep eutectic solvents (DESs) for effective absorption NH3/CO2 separation investigation. All the [MEA][SCN]-based DESs exhibited good performance. Notably, [MEA][SCN]-PhOH (1:1) realized an atmospheric capacity 0.2459 g NH3·g–1 DES selectivity 194.53 at 303.15 K. Based on experimental data, new process recovery melamine tail using (DES-M) developed simulated operational parameters optimization, heat exchange network design, evaluation. DES-M can recycle purity 99.6% save 82.01% utility costs compared water scrubbing method. integration design in reduces 66.94% low-pressure steam 9.00% costs. Specially, optimized exceed 59% after-tax rate return renewable energy.
