【Abstract】 In this article, it is emphatically discussed how the floating pressure control technique works and to be realized, which is a control based energy conservation method for distallation process in petrochemical plant. The principle of floating pressure control, the control scheme and its realization and some problems in design are illustrated by analyzing the relationship among distillation process, operation pressure, relative volatility and energy consumption, followed by an example to show the effect and benefits of the floating column pressure control.更多还原
