Separation (Advanced Column)
BEco grade
Midstream2 facilities tracked
Column-based solvent extraction technology (e.g. RapidSX™ by Ucore) that accelerates aqueous-organic contact in closed vertical columns rather than open mixer-settler tanks. Cuts organic solvent inventory ~75%, raffinate discharge ~73%, physical footprint ~75%, and cycle time from 10-14 days to ~24 hours versus conventional SX, while achieving equivalent purity output.

Technical Moat
HighThe moat is proprietary column packing geometry and flow dynamics that sustain mass transfer at commercial throughput. Ucore's RapidSX™ IP is US-held and DoD-supported, representing a credible Western alternative to Chinese mixer-settler chemistry.
