An MVC system is to be designed to produce 5000m3/d of fresh water. The boiling temperature is 700C and the temperatures of the compressed vapour and condensate are higher by 8 oC and 3C, respectively. The salinity of the feed seawater is 38000 ppm and the rejected brine salinity is 70000 ppm. For preliminary design considerations neglect thermodynamic losses, assume constant specific heat for all liquid stream (4.2 kJ/kg OC), constant specific heat for the vapor streams (1.884 kJ/kg OC), and constant overall heat transfer coefficients of 2.7, 7.2, and 7.8 for the evaporator, distillate preheater, and brine preheater, respectively. Calculate the following: Mb,Mf,Tf,To,Ab,Ad,Ae,W and the cost Determine the effect of boiling point change( assume 5 values of Tb) recalculate your values, Draw a graph represents the change effect with W
