Abstract

Ionic liquid (IL)-NH3 double-effect absorption systems are proposed to utilize the high-temperature exhausted gas (250-500 oC) from engines with the purpose of delivering the required refrigeration of the fishing vessel. In this work, practical concerns on the stabilities, toxicities and viscosities of IL-based fluids have been discussed. Monte Carlo (MC) methods have been applied to extend the vapor-liquid equilibrium properties of selected IL-NH3 working pairs to high-temperature conditions. Additionally, a case study based on a specific fishing vessel has been carried out to investigate the economic feasibility of the proposed systems.
