Case study

MSF OT plant. The plant contains two main section; these are the brine heater ( or the heat input section ), the flashing stages ( the heat recovery section (24 stages) are used to produce 370 Kg/sec of Distillate water. The following specifications are made to obtain the plant design parameters and performance characteristics and cost .

The specifications include the following :

. Intake seawater Temperature, T_SW =25 ⁰C .

. Steam Temperature, T_S =116 ⁰C .

. Top brine Temperature, T₀ = 106 ⁰C .

. Brine Temperature in the last stage, T_n = 40 ⁰C .

. Salinity of intake seawater , Xf = 42000 ppm .

. Vapor velocity in the last stage , V24 = 6 m/s .

. Brine mass flow rate per stage width, V_b = 180 kg/m.s .

. Weir friction coefficient, Cd = 0.5 .

. Tube velocity of seawater stream, Vr = 2 m/s .

Changing the intake seawater Temperature, T_SW = 20 , 25 , 30 , 33 ⁰C
