Flowable Channels

Performance of flow capacitive deionization modules, such as those used in Se(L)ect(i)vity project, is not only influenced by membranes. The geometry of flow electrode channels also has a strong influence on salt adsorption capacity (SAC). Thus, advanced computing project Flowable Channels (CPCA/A0/401985/2021) will focus on Optimization of flow electrode channel geometry to boost recovery of lithium from brines by flow capacitive deionization (FCDI).

High performance computing (HPC) resources of the National (Portuguese) Network for Advanced Computing will be used to perform computational fluid dynamics (CFD) simulations of the flow of carbon slurries (flow electrodes) in FCDI modules.

The main objective is to improve the design of these flow electrode channels to ensure uniform distribution and mixing of carbon slurries.
