A solution of organic colloids ( solid material ) in water at 6 0 deg C is fed to a single - effect evaporator
A solution of organic colloids solid material in water at deg C is fed to a singleeffect evaporator to produce wt concentrated solution. Saturated steam at bar absolute pressure is supplied to the heating system of the evaporator at a flow rate of kg h The operating temperature of the evaporator is deg C ie the temperature in the evaporator The specific heat of the feed solution is J g K and the latent heat of vaporization of the solution may be taken equal to that of water. The solution has negligible boiling point elevation and all kind of heat losses to the environment may be neglected. a Calculate the required feed flow rate kg h and solid content wt solids of the feed solution in order to produce kg h wt concentrated product solution. b If the estimated overall heat transfer coefficient is W m K calculate the required heat transfer area in m c Write down your recommendations maximum two to improving the operation ie improving its efficiency of this evaporator.
