Sodium Hydroxide (NaOH) solution contains 4 wt% NaOH is fed into a series of 3 evaporators. In each unit, equal amount of water is vaporized and then condensed and combined to obtain a fresh water product stream. The 3d evaporator output stream contains 8 wt% NaOH. With the help of a complete process flowchart, determine the fractional yield of fresh water from the evaporated process (kg H2O recovered / kg H20 in process feed), the percentage of NaOH in the solution leaving the 1st and 2nd evaporator and the fractional yield of the fresh water after this stage,

Question
need the correct ans asap
Transcribed Image Text:a) Sodium Hydroxide (NaOH) solution contains 4 wt% NaOH is fed into a series of
3 evaporators. In each unit, equal amount of water is vaporized and then condensed
and combined to obtain a fresh water product stream. The 3d evaporator output stream
contains 8 wt% NaOH. With the help of a complete process flowchart, determine the
fractional yield of fresh water from the evaporated process (kg H2O recovered / kg H20
in process feed), the percentage of NaOH in the solution leaving the 1st and 2nd
evaporator and the fractional yield of the fresh water after this stage.
