EVAPORATION SECTION

     PROCESS DESCRIPTION FOR EVAPORATION SECTION

This scheme will be used for production of Dry total solid solids. This is multiple effect evaporation system. Total THREE effects of evaporation will be supplied. All Heat Exchangers will be Falling Film type evaporators. All effects are provided with circulation cum transfer pumps.
Feed will come to Feed Pre-heater 1-4 & enter in Effect–1. Concentrated liquid will be transferred from Effect -1 to Effect – 2 by circulation cum transfer pump. Same way conc. Solution will flow from Effect -2 to Effect - 3, From Effect-3 solution will be transferred to by circulation cum transfer pump.

Effect-1 will be heated by dry saturated steam. Vapors from Effect-1 will be used for heating Effect-2 & so on up to Effect-3. Effect-3 vapor from vapor liquid separator will be sent to INDIRECT CONTACT TYPE surface condenser. Process Condensate from Effect-1 to 3, as well as surface condenser will be collected in Process Condensate pot & will be transferred to desired location by Process Condensate Pump. This Concentrate will come out as product.

     HIGH PRESSURE NOZZLE ATOMIZATION SYSTEM

The feed from feed tank is fed to the atomization system through a variable speed feed Pump .The atomised particles come in contact with the hot air entering the chamber in a co-current fashion through an air distributor .

The dried product entrained with the exhaust air is separated in a high efficiency cyclone separator and discharged through the rotary air lock valve. The exhaust air is further passed through a wet ventury scrubber for recovering the fines not separated in cyclone. Clean air is then vented to the atmosphere.

The process air is handled by means of two centrifugal fans.
