Steam economy increases steadily in multiple-effect evaporators as the number of effects increases. Adding a thermocompressor to a three-effect system can approximately double the economy, but that pales in comparison to the potential steam economy of an evaporator with MVR — which is 5–10 times that of the three-effect evaporator.
