ECOVAP - RANGE OF EVAPORATORS

Praj delivers high end solutions for varied application including concentration by evaporation, heating and cooling by special heat exchanger, separation and scrubbing by distillation and many others.

Evaporation is a process of vaporization of asolvent from asolution in orger to increase the concentration of the solute. Building on its expertise, Praj offers concentration solutions using energy efficient Evaporation Technology.

We aim at delivering high product quality and overall energy efficiency.

Falling Film Evaporator with boiling inside the tubes. The feed to the evaporator is fed to the top of the Calandria through efficient liquid distributors. Steam is given on the shell side. The concentrate is collected at the bottom. The same operation is repeated in multiple effects to achieve steam economy.

The liquid is heated in a heat exchanger and flashed in a flash vessel to achieve desired concentration. Multiple pass are provided to get required flow rate. Evaporative Crystallization can be efficiently achieved in ECOVAP FC.

The feed at near boiling is fed to the bottom of the Calandria. It is then pumped inside the tubes. Steam is provided on the shell side. Liquid and vapor are separated in the vapor separator at the top. Multiple effects are used to achieve higher steam economy.
