Abstract
A multi-stage flash reversal unit includes a housing; plural stages located inside the housing; an evaporation port that receives a water feed having a first temperature; a condensation port that outputs a concentrated water feed having a second temperature, which is lower than the first temperature; and a cooling unit that cools down the concentrated water feed.
Claims20
A multi-stage flash reversal unit comprising:
- a housing;
- plural stages located inside the housing;
- an evaporation port that receives a water feed having a first temperature;
- a condensation port that outputs a concentrated water feed having a second temperature, which is lower than the first temperature;
- and
- a cooling unit that cools down the concentrated water feed,
- wherein the evaporation port and the condensation port are arranged within the housing so that the water feed enters first the evaporation port when the water feed first enters the housing, and the concentrated water feed exits the condensation port last when leaving the housing.

A method for producing distilled water with a multi-stage flash, MSF, reversal unit, the method comprising:
- providing a water feed, having a first temperature, to an evaporation part of the MSF reversal unit;
- flash evaporating an amount of water from the water feed in the evaporation part, to obtain vapors and a concentrated water feed;
- cooling down the concentrated water feed in a cooling unit, wherein the cooling unit lowers a temperature with a given temperature interval;
- providing the cooled, concentrated, water feed to a condensation part of the MSF reversal unit;
- producing the distilled water by condensating the vapors in the condensation part;
- and
- outputting the concentrated water feed at a second temperature, which is lower than the first temperature,
- wherein an evaporation port that receives the water feed and a condensation port that expels the concentrated water feed are arranged within a housing of the MSF reversal unit so that the water feed enters first the evaporation port when the water feed first enters the housing, and the concentrated water feed exits the condensation port last when leaving the housing.

A multi-stage flash reversal unit comprising:
- an evaporation part that receives, at an evaporation port of a housing, a water feed having a first temperature and flash evaporates water from the water feed to form vapors;
- a condensation part that condensates the vapors to generate distilled water, and outputs a concentrated water feed having a second temperature, which is lower than the first temperature, at a condensation port of the housing;
- and
- a cooling unit that cools down the concentrated water feed,
- wherein the evaporation port and the condensation port are arranged within the housing so that the water feed enters first the evaporation port when the water feed first enters the housing, and the concentrated water feed exits the condensation port last when leaving the housing.
