Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Design and investigation of algorithms for the reflux ratio control under process of azeotrope rectification Shevchuk V.P., Bocharov M.G. The structural model of rectifying column is developed with the purposes to design the control algorithms for reflux ratio and to give the mathematical formulation for the rectification process. In the issue three control algorithms for reflux ratio have been worked out. The verification and the effectiveness of these algorithms have been carried out.
