Multicolumn Distillation Plant

GEM’S Superfine Quality Multicolumn Distillation Plant is based on the principal of interstage heat exchange to produce pure pyrogen free sterile distilled water

A part of feed water on the inside of the heat exchanger tubes is converted to steam because of surface film evaporation. A predetermined minimum amount passes through the column which causes both rapid heating of feed water and rapid cooling of boiler steam, therefore creating vapours at high velocity under pressure. This vapour rising through the entertained section is subjected to a 180 turn caused by centrifugal force.

Due to spiralling motion, the pure vapour rises upward through a vertical section outside the heat exchanger. Due to this unique centrifugal seperation technique, the impuritites such as endotoxins and pyrogen are removed. The purified vapour (steam) then moves towards the upper portion of the column.

The pure steam in the first column serves as the source of heat for the second column. This process is repeated in all the 4 to 5 columns or more. Each column is working at a slightly lower temperature and pressure than the proceeding one. The heating energy requirements are reduced by 70% as external heat is required to vapourise only 30% of the feed water.
