Feed temperature in distillation column
WebJul 18, 2024 · Greg: Distillation column control is key to achieving consistent product purity that meets specification limits without consuming excessive energy. Composition control via either analyzer or inferred prediction is critical. A proportional-integral-derivative (PID) column temperature is typically used if a temperature can be found that correlates well … WebFor the specification of distillation operation, R or R/Rminis used traditionally because the distillate pproduct is often the more imppportant product Feed condition Value of q Subcooled liquid >1 • q: ratio of the increase in molar reflux rate across the feed > 1 Bubble-point liquid 1 Partially vaporized L F /F reflux rate across the feed
