Vapour pressure vs. Temperature data from PRO II and from Antoine’s equation with coefficients from table 6 are plotted in figure 4. From the plot it is evident that the vapour pressure data calculated from Antoine’s equation is in close agreement with PRO II simulation.
Calcuation withA ntoine's Equation – An Inexpensive Solution
Major drawback associated with inferential temperature control is misinterpretation of temperature change as a composition change due to pressure variations in distillation columns. This drawback can be overcome by implementing an inexpensive pressure compensated temperature control technique as illustrated in this text. Antoine’s equation can be used effectively for calculation of pressure compensated temperature for hydrocarbon systems.
