Supplementary data Energy efficient vortex-enhanced water evaporation technology for concentrated brine management: Theory and process simulation evaluation

Description

Data simulation for Desalination drinking water systems and industrial processes generating high salinity streams require practical brine management options for disposal and/or treatment.  Treatment most often involves large capacity brine concentrating processes, on the order of 2000 m3/day, that rely on water evaporation, vapor compression, and condensation.  Tornadic One-Pass™ (TOP™) technology adds an aerosol-generating “Pod” device to the evaporation step with the goal of energy efficient operation even at smaller scales.  The principles behind the tornadic flowfield that breaks up and aerosolizes water injected into the Pod are introduced.  Design of a 6.8 m3/day TOP™ demonstration system producing a NaCl slurry (55 wt% solids) from a 22 wt% NaCl influent is described.  Simulations of the system with three influent brine concentrations and three forms of final NaCl concentrate are presented and predicted energy usage is compared to estimates for conventional systems.  By varying simulation process parameters, the heat transfer performance of the evaporator/condenser is identified as having a large impact on overall efficiency.  TOP™The TOP™ system is anticipated to be most competitive, on an energy usage basis, with conventional concentrator/crystallizer systems when processing higher salinity brines and producing final concentrates containing precipitated NaCl.
