Finding Sustainable Deep Eutectic Solvents for an Efficient Separation of CO₂ and NH₃ in Melamine Production with Soft-SAFT.

ABSTRACT: Industrial processes frequently release tail gases containing harmful components, such as carbon dioxide (CO₂) and ammonia (NH₃), with significant environmental implications. Effective separation and recovery of these gases are critical for reducing pollution and enhancing resource efficiency. This paper investigates the use of deep eutectic solvents (DESs) to capture and separate CO₂ and NH₃ from melamine production tail gases, offering an alternative to traditional methods such as coproduction systems and water scrubbing. Choline chloride ([Ch]-Cl)-based solvents with ethylene glycol (EG), urea (UR), and glycerol (GL) are assessed for selective gas absorption using the soft-SAFT Equation of State (EoS). This approach has been used to model the
