Multi Column Distillation Plant By Ravi-kiran Industries

Multi Column Distillation Plant DescriptionMulti column distilled water still is designed to produce sterile, pyrogen free distilled water conforming to I.P. / B.P. specifications. The still works on interstage heat exchange principle whereby the distillate is produced at a fraction of the cost as compared to single column stills. All contact parts are made out of AISI 316 quality and mirror polished. OperationMulti column distilled water still works on interstage heat exchange principle. The pre-heated feed water is fed to the first column where it is heated by means of steam from the boiler. Due to heat exchange, surface evaporation of the feed water takes place whereby a part of the feed water is converted into steam. In the process the steam itself condenses back to water. The steam with high velocity and under pressure passes through a specially designed spiral which creates a unique centrifugal force which removes impurities such as pyrogens and exdotoxins which are blown out of the system. Condensing vapor from the previous stage is used as heating vapour for the next stage. The process is repeated through the last column, each column working at a lower pressure and temperature than the previous one. Due to the pressure difference between the columns, the energy supplied to the first column is repeatedly re-used in the system. Only the first column is heated using an external source of energy and only the vapour from the last column is condensed with external cooling water. Thus upto 70% energy is saved.Salient Features100% pyrogen free distilled water conforming to I.P. / B.P. specifications.High initial cost but low operational cost.Saving upto 70% of energy as compared to single column stills.Low on maintenance as no moving parts except feed pump.The unit can be operated at a higher steam pressure to get upto 50% higher output.Automatic dumping of sub-standard distillate.Low level controls for feed water.Conductivity meter to continuously monitor the quality of final distillate. Scope of SupplyS.S. 316 quality multi-stage pump for Feed water, max. pressure of 10kg/cm2S.S. 304 Centrifugal pump for cooling water.S.S. 316 quality Surge tank with level switch to maintain the level of feed water.S.S. 316 quality pneumatic three way valve for automatic dumping of sub-standard distillate.S.S. 304 stand instead of mild steel stand.Fully automatic operation, controlled through a specially designed S.S. electronic panel board with self regulating sensors to keep each of the operating parameters within the pre-set limits, hence no skilled labour required to operate the plant.Magnetic level switch in the first column to maintain the level of feed water in the column.Pressure switch to monitor the pressure of feed water.Pressure gauges, safety valve, rotameters etc. *No extra cost for the surge tank and S.S. stand.
