3/28 · If your question is about a real-life distillation column, we do not have enough information to answer whether the feed tray should move higher or lower. This is because in

2005/9/1 · The effects of feed locations to the design of reactive distillation are explored. In this work, ideal reactive distillation systems are used to illustrate the advantage of feed trays

Determining the number of stages required for the desired degree of separation and the location of the feed tray is merely the first steps in producing an overall distillation column design. Other things that need to be considered are tray spacings; column diameter; internal configurations; heating and cooling duties.

By choosing the optimum feed tray location for the columns, about 16% of energy consumption could be reduced. Key words: Distillation, Process Control, 

word "optimum" implies the feed plate location, with fixed number of equilibrium trays in the column, that will provide for a specified separation in the 

SEPARATION COLUMNS (DISTILLATION, ABSORPTION AND EXTRACTION) 557 Methods for predicting the entrainment from sieve plates are given in Section 11.13.5, Figure 11.27; a similar method for bubble-cap plates is given by Bolles (1963).

The feed to a distillation column can be liquid or vapor, or both, depending on the temperature, pressure, and composition of the feed. To quantify the thermal condition of the feed, the parameter q is defined as the fraction of the feed that is liquid. It follows that 1 — q is the fraction of feed that is vapor:

Feed is a saturated liquid: HF = hL ⇒q = 1, q. Feed Plates • Feed plates are fitted in the distillation column to separate different mixtures •.

Fractionation - Another term for distillation, or fractional distillation. Feed - The liquid and/or gas feed into the distillation column. The tray below the inlet nozzle is called the feed tray. Heavy Component - The component with the lower relative volatility, for simple hydrocarbon this is the component with the higher molecular weight. . Found in higher concentration in the bottom

Abstract—The paper considers the effect of feed plate location on the interactions in a seven plate binary distillation column. The mathematical model of the distillation column is deduced based on the equations of mass and energy balances for each stage, detailed model for both reboiler and condenser, and heat transfer equations.
