Multi Column Distillation Plant
Multi Column Distillation Plant
Salient Features
Low maintenance as there are no moving parts except feed pump
The unit can be generate 50% higher output by increasing pressure of steam.
Application
To produce sterile, pyrogen free steam conforming to IP/BP specification.
Operation Principle
Inner stage heat transfer principle
Pre-heated feed water is fed to the 1st column, wherein it is heated by steam. Due to heat transfer and surface evaporation of feed water, part of it is converted into steam
Condensing vapour from the last stage is used as heating vapour for next stage. The process is repeated through the last column, each column working at a lower Pr. And temperature than previous one,.
Due to the Pr. Difference between columns, the energy supplied to the 1st column is repeatedly reused in the system.
External source of heat energy is used only in 1st column and only vapour in last column is condensed with external cooling water, thus saving
