Just published a comprehensive update on HCl electrolysis technology in the Portfolio Planning PLUS Ltd database - a critical process for chlorine recovery, in particular in isocyanate manufacturing.

KEY HIGHLIGHTS:
✅ Three commercial technologies compared: ODC, Diaphragm, and Membrane cells
✅ Energy efficiency gains: ODC process delivers 30% energy savings (733-1070 kWh/t Cl₂)
✅ Process integration: Detailed plant configurations for each technology variant
✅ Industrial applications: Focus on chlorine recycle in MDI/TDI production
