Webwhere, 1 < θ < α LK and q is the quality of feed. 8. Select an operating reflux ratio, R as a factor of minimum reflux ratio, typically a factor of 1.2 is considered. Number of stages, N is calculated based on Gilliland's correlation. WebFeed temperature is 50 0 C and reflux ratio for the column is 1: 3. Column is operating at atmospheric pressure. Distillation column material balance and other properties of all streams are as below: Heat Duty Calculation for Column at Saturated Reflux Let us calculate total heat input at column reboiler for above operating conditions.
WebHence, there is a delicate balance among these factors, and often the reflux ratio has to be continuously adjusted to meet the change in feed composition and other day-to-day variations. As indicated in Fig. 11-7, the optimum reflux ratio occurs at the point where the sum of fixed charges and operating costs is a minimum.
