Abstract

Spray Flash Vacuum Distillation (SFVD) offers a groundbreaking alternative to conventional distillation technologies, such as thermal and membrane distillation. Building on our recently published one-stage study, this paper extends the research by introducing a two-stage SFVD model for continuous distillation. Leveraging an in-house algorithm and custom-developed codes, the study aims to integrate key system components—namely, the flash evaporation chamber, feed brine and cooling water circulation loops, parallel plate condensers, vacuum pump, and non-condensable gases storage tank. Utilizing thermo-fluid principles, the study adopts an optimized approach to model a sequential reduction in vapor pressure. This method facilitates active flash evaporation and optimizes condensation rates, particularly in later stages where vapor temperature gradually decreases. The proposed model is capable of calculating critical system characteristics, such as the spray flash rate of evaporators, yield rate, and thermodynamic properties of the steam/brine cycle. Additionally, the model evaluates essential thermo-fluid parameters, including energy consumption, thermal efficiencies, and heat recovery rates.
