Advanced Separation Process

An MSMPR crystallizer (operating volume =100L ) is operated in steady state at 60C with a residence time of 50 minutes. If the feed has a solute concentration of 250g solute/L solution, then determine (i) the dissolved concentration of the solute in the crystallizer; (ii) the productivity of the crystallizer (in kg crystals/day). Data: G=5106cB=11014c3.8 where G=m/s,c=kg solute /L solution, B=#/m3s The product solubility is given by c(T)=0.0009T+0.1 where c=kg solute /L solution, T=C. The solute crystal density may be taken to be 2,000kg/m3, and the volumetric shape factor of the crystals may be taken to be 0.8
