Desalination

Desalination consists mainly of sea-water desalination for industrial use or for obtaining drinking water. Three main processes are used: multistage flash, thermocompression and reverse osmosis.

Multi Stage Flash

Desalination is carried out by flashing seawater in a vacuum, in a series of cascade chambers, operating at decreasing temperatures and pressures. The chambers have a demister to separate the brine entrainments from the saturated steam and a tube bank supplied with seawater that condenses the saturated steam and preheats the feed water.
Distinctive characteristics of the Costacurta internals used in the desalination process are:

  • Long-standing experience in the design and production of this type of internals
  • Optimised flexible production process
  • Wide range of types and solutions
