-A continuous flow stirred cell operating at point conditions has heen developed for the study of mass transfer in distillation. Results for the methanol-isopropanol and methanol-ethanol binary systems showed that 85-10096 of the resistance to mass transfer resided in the vaponr phase, and that the vaponr side coefficients correlated well with those obtained ia the same cell for gas phase controlled absorption. Plun rates for the ternary system methanol-ethanoi-isopropanol were in fair agreement with those predicted from the binary data, using a modified form of the Krishoa-Standart theory. It is concluded that the experimental technique shows considerable promise, but requires further development to overcome discrepancies in the interfacial heat balance.
