Multi Column Distillation Plant

The Multi Column Distillation plant produces low conductivity pyrogen /endotoxin free Water For Injection (WFI) by stage distillation process. As the name suggests the unit consists of a series of pressure vessels in the form of columns / stills which are inter connected. Boiler steam is utilised only in the first column to produce pure steam and remaining columns utilize this pure steam to produce further more pure steam. During this heat exchange process, pure steam condenses. Additional condensers are provided on top to condense the pure steam completely to produce WFI. The plant is designed for maximum heat recovery and hence very economical inoperating cost.
