Praj is a process engineering company with deep understanding of various industrial processes and related systems. 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 a solvent from a solution in order to increase the concentration of the solute. Building on its expertise, praj offers concentration solutions using energy efficient evaporation technology. 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.
