| Popis: | In this analysis, based on the bubble point method, a physical model wasestablished clarifying the interactions (mass and heat) between the species present in thestreams in circulation in the column. In order to identify the externally controlled operatingparameters, the degree of freedom of the column was determined by using Gibbs phase rule.The mathematical model converted to Fortran code and based on the principles of: 1) Globaland local mass conservation balance, 2) Enthalpy balance, and 3) Vapour-liquid equilibriumat each tray, was used to simulate the behavior of the column, concentration distributions,temperature and streams for each phase along the column at high pressure in each tray. Theenergy consumption at the condenser and the boiler was also evaluated using the Starlingequation of state. |
