Distillation process design & Desalination membrane device design
1. Patents for Distillation
- Active vapor distributor for dividing wall column to control vapor split ratio, and for packed column
to maintain uniform vapor distribution covering wide operation range.
- Multi-effect distillation for acetic acid dehydration of azeotropic distillation process to reduce
energy consumption.
2. Patents for Desalination/Water recovery
- FO-Distillation hybrid desalination process which ammonium bicarbonate solution is used as the
draw solution. Low temperature below 110 C waste heat can be utilized.
- FO combined membrane which the pervaporation membrane is combined with FO membrane in one
module, which does not need high pressure pump or the additional draw solution regeneration
system. Low temperature below 90 C waste heat can be utilized.
