MULTIPLE EFFECT EVAPORATORS

Separation of solid from watery solutions by simple evaporation, involves considerable expenditure. Selling price of some products may absorb the expenditure but for ETP and inorganic salts, multiple effect evaporation is unavoidable.

Multiple effect aims to separate water from solids with as low water vapor formation as possible. This is achieved by carrying out condensation at progressively lower temperatures. Last effect is usually under vacuum.

Yajna Fuel Services can design, supply, erection and commission such systems. Packages are also available to increase no. of effect from 3 to 6 or 4 to 8 depending on cost of steam and recovery of water designed.

Such systems having been found useful for Textile, metal processing, pharma and many other process industries. System is usually installed as last piece of equipment for zero liquid discharge plant.

Retrofit of one more effect to your existing MEE System

MEE System saves energy as per No. of effects. At a time when fuel was cheaper lesser no. of effects was justifiable, not anymore. Additional effect will save energy further as heat going to condenser reduces. We propose to add effect before the existing first so that it can without adding pressure and tougher conditions of boiling.

We suggest to introduce air cooled condenser / feed preheater at this stage but major savings are achieved by adding extra effect or you can choose.

Please allow our engineer to understand you existing system so that operators get system familiar to them.
