Answer:
feed = 220.77 kg/s; maximum production rate of solid crystal = 416 kg/s; the rate of supplying fresh feed to obtain the production rate = 1.6
Explanation:
Material or mass balance can be used to estimate the mass flow rates of all the streams in the diagram shown in the attached file.
Overall balance:
Water:
Using substitution method, we have:
= 220.77 kg/s
= 4.16 kg/s
The maximum production rate of solid crystal is = 10*4.16 = 416 kg/s
Around evaporator:
kg/s
Around the mixing point:
Solid crystal:
Using the last two equations, we can obtain:
kg/s
The rate of supplying fresh feed to obtain the production rate is:
= 352.5/220.77 = 1.6
