energy aspects

Reading time:

The type of energy chosen (low pressure/medium steam pressure or electricity) is essential and must be studied in detail in order to obtain optimal operating costs.

Measures to reduce energy consumption are associated: mechanical steam compression (MSC), thermal steam compression (TSC) and multiples effects (ME).

Multiple effects configurations are more advanced: each stage recovers the condensation’s latent heat from the previous stage, the number of stages being limited by the feed temperature from the heat exchanger in the first stage and the condensate cooling temperature in the last stage.
