Ammonia absorption in ionic liquids-based mixtures in plate heat exchangers studied by a semi-empirical heat and mass transfer framework

Unfavorable transport properties have always been pointed out as the key factors that hinder the application of ammonia/ionic liquids (NH ₃ /ILs) in absorption cycles, while heat and mass transfer of these new fluids in components have been rarely reported. In this study, a corrugated plate heat exchanger is selected as the...

Effect of type-III Anti-Freeze Proteins (AFPs) on CO₂ hydrate formation rate

CO2 hydrate slurry is a favourable direct coolant of fresh products due to its large latent heat and phase change temperature around 7 °C. Continuous production of this slurry is, however, difficult to realise due to the high rate of hydrate formation. The use of additives is proposed with the purpose of decreasing the formation rate so that the...
