of energy can be significantly reduced; however, investment costs increase when adding evaporation effects. This highlights the importance of investigating trade-offs between savings in steam and added investment in order to find the optimum number of effects. In addition to multiple-effect evaporation, vapour recompression
In an evaporator using tubing, after the water begins to boil, bubbles will rise and cause circulation, facilitating the separation of the liquid and the vapor at the top of the heating tubes. The amount of evaporation that takes place depends on the temperature difference …
medium in the steam chest of the next effect, it is called multiple effect evaporation. Single effect evaporation is simple but fails to utilize the steam effectively, while multiple effect evaporators evaporate more quantity of water per kilogram of steam consumed in the evaporation process.
forced circulation evaporator to achieve zero liquid discharge process for pharmaceutical effluent. Reverse osmosis reject is conveyed to multiple effect falling film evaporator to separate salt and reusable water. This study aims to diagnose the ills of the multiple effect evaporator to improve the efficiency and energy consumption.

This improved the efficiency of the multiple effect evaporator significantly resulting in reduction of chemical oxygen demand and total dissolved solids by 91.5% and 96% respectively. This also achieved reduction in energy consumption by 40% reducing the overall live steam consumption from 0.55 to 0.32 kg/kg of effluent treatment.
How Evaporator Coils Increase Efficiency. This occurs at the same time that the blower in the air handler or furnace is absorbing heat from your house through the cooling fins. As this warm air travels over the evaporator coil, the cold coils extract this heat and the liquid is converted back to a gas.
diagnose the ills of th e multiple effect evaporator to improve the efficiency and energy consumption. Diagnosis Diagnosis involves vacuum testing and hydro testin g.
1.2 Problems associated with multiple effect evaporators. The problems associated with a multiple effect evaporator system are that it is an energy intensive system and therefore any measure to reduce the energy consumption by reducing the steam consumption will help in improving …
