A system for the recovery of sucrose from affination syrup has been developed. The system consists of membrane filtration, softening using a spent NaCl stream, and Organo's New Simulated Moving Bed Chromatography, which is capable of separating three components. With the expected purity and recovery of sucrose with this system of 92-97% and 90-93%, respectively, this system will be a promising alternative for sugar refineries which seek improvements.

The robustness of three kinds of PID decoupling control systems of CSTR with uncertain dynamics is investigated. It has been found that within 5K or 5% of concentration of setpoint change in temperature or concentration of reactant of CSTR, each control system is robust enough for there to be less than 10% modeling errors in frequency factor and heat of reaction. Among the modeling errors in kinetic parameters, that of activation energy gives the most significant effect on the robustness of a control system of CSTR. Computer simulations have shown that a PID linearizing control system is much less robust against modeling error in activation energy compared to the other two PID decoupling control systems.
