ABSTRACT

The need in fresh water for drinking and industrial applications is increased permanently. This challenge can be solved by using sea water desalination. One of the most popular methods of desalination of large volumes of water is a vacuum distillation technology. However, vacuum desalters need the optimization of their design and/or operation. The desalters' optimization is carried out with account for many different parameters that affect their efficiency. The purpose of the present work is a preliminary analysis of the influence exerted by the internal distiller vacuum level and by the salt concentration in sea water on the operation of the main distiller's construction units. It is shown that an increase in the vacuum level worsens the operation of steam compressor and of water ejection unit. Pressure reduction improves the performance of the heater unit, and it does not affect the vaporizer unit operation. An increase in the sea water salinity worsens the operation of the unit and vaporizer. It does not influence the performance of other desalter units.
