A two-effect falling-film evaporator with thermocompressor requires about 0.32 kg of steam to evaporate 1 kg of water, and a five-effect evaporator requires 0.09 kg of steam. Without the thermocompressor, the specific steam consumption would be approx. 0.55 and 0.2 kg per kg of water evaporation respectively.
