GEM's Superfine Quality Multi Column Distillation Plant is based on the principal of interstage heat exchange to produce pure pyrogen fee sterile distilled water.
A part of feed water on the inside of the heat exchanger fubes is converted to steam because of surface film evaporation . A predetermine minimum amount passes through the column which cause both rapid heating of feed water and rapid cooling of boiler system, therefore creating vapours of high velocity under pressure. This Vapour rising through the entertaind section is subjected to a 180 furn 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 separation technique. The impurities such as endotoxins and pyrogens 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 id respected in all the 4 to 5 column or more . Each column is working at a slightly lower temperature and pressure than the preceeding one. The heating energy requirement are reduced by 70% as external heat is required to vapourise only 30% of feed water.
