A MODEL FOR PREDICTING THE NUMBER OF MASS-TRANSFER UNITS AND THE EFFICIENCY OF SIEVE TRAYS IN RECTIFICATION

The design of rectification columns is based on the method thetheoretical tray and actual setupof real trays carried out with help various kinetic characteristics, such as efficiency. relation between local integral efficiency a complex function geometric, physicochemical hydrodynamic factors. A theoretical for calculating has not yet been proposed, because setting influence number Empirical correlations or traycan be found in literature. aim present work to make comparison calculated data by means model known from literature experimentally obtained Tetrachloromethane-Toluene binary mixture laboratory single-sieve column. Among tasks currentwork also determine parameters applied model. proposed semi-empirical allows calculation mass-transfer units and, therefore,of
