Developing computer program for a Design a single and multi stage flash desalination plant

Résumé

Multi stage flash desalination process one of the most techniques
which is widely used for large scale drinking and industrial water
production, for the last decades most of MSF desalination units
were installed in the middle east and north Africa.
The heat transfer area is different from stage to stage due to the
boiling point elevation in the brine solution, therefore the precise
calculation is required to achieve optimum design parameters.
In this paper, a computer program will be developed to estimate
all the variable using heat and mass balance equations for each
stage separately, and this will result accurate data of heat transfer
area, brine flow, produced steam, and accurate number of pipes,
which will reduce the total capital cost of MSF desalination plant.
Finally the output data will be assessed against real design data
of a 1200 m3/day msf desalination unit.
