Formation Kinetics Evaluation for Designing Sustainable Carbon Dioxide-Based Hydrate Desalination via Tryptophan as a Biodegradable Hydrate Promotor

Desalination using hydrates is a developing field, and initial research promises commercially feasible approach. The current study proposes the natural amino acid, namely tryptophan, as biodegradable gas hydrate promotor for desalination applications to speed up formation process. Its kinetic behavior separation capabilities with CO2 were investigated. studies carried out varying concentrations (0.5, 1, 2 wt.%) of tryptophan at different experimental temperatures (274.15, 275.15, 276.15, 277.15 K) 3.5 4.0 MPa pressure 1 wt.% brine concentration. induction time, rates, uptake, water recovery are characterized reported in this work. Overall finding demonstrated that efficiently acted (KHP), increased quantities further supported almost all studied conditions. kinetics also it shortens time by 50.61% increases 144.5% rate addition 274 K temperature condition. discovered similar conditions, improved uptake 124% moles 121%. Furthermore, (0.5–2 enhance due hydrophobic nature tryptophan. Findings revealed meaningful link between operating observed exact settings. High pressures facilitate reduced times relatively higher highlighting subcooling effect on Overall, can be concluded considerably enhances hydrate-based process, making more sustainable cost-effective.
