CORE IPEX VRB ELECTROLYTE

Three important refinements of the IPEX SMB IX technology were recently commissioned at our piloting facility in South Africa. These include demineralisation of process and eluent make-up water, expanded resin rinse facilities and process tweaks to further enhance eluate quality.


These further improvements promise ultra-pure pregnant solutions suitable for direct conversion to premium grade products such as VRB electrolyte. Early indications during ramp-up already confirms a major shift towards the ultra-pure objective which the IPEX team will soon be able to confirm in eluate composition after week or two of steady state operation.


IPEX SMB IX pilot plant


The three-stage demineralisation plant shown below is producing low conductivity make-up water of less than 10ppm TDS


Three-stage IX demineralisation pilot plant


The expanded IX rinse system allows multiple counter current rinsing of resin beds effectively removing any entrained salinity which is essential to ultra-pure eluates.


New rinse system


This novel capability promises VRB electrolyte produced at compelling cost from a range of secondary resources.
