Choosing Trays and Packings for Distillation
نویسنده
چکیده
Distillation towers are essential to the chemical process industries (CPI), so it is imperative that they are properly designed and operated. Tower internals are arguably the most important piece of process equipment, since they cannot easily be accessed after startup. If the tower internals malfunction, the distillation tower will follow suit and the entire chemical process will suffer. This article explains how process simulations of the distillation tower provide the necessary data for engineers to select proper tower internals. These internals can be trays or packings, each of which has a set of characteristics that makes one more appropriate for a particular separation application than the other.

The D+r Tray: Novel Laboratory Equipment for Studying Heterogeneously Catalyzed Reactive Distillation – Design and Simulation-based Validation
In this paper, novel equipment for laboratory studies of heterogeneously catalyzed reactive distillation is described. The so called D+R tray equipment consists of a combination of conventional bubble cap trays with sections that are filled with catalyst and through which the liquid flows when it passes from one distillation tray down to the next. It is designed so that the catalyst can be easi...
متن کاملSeparation Performance of Structured Packed Columns: a Comparison of Two Modelling Approaches
INTRODUCTION Structured packings of the corrugated sheet type have become increasingly popular for the application in distillation and absorption columns, due to their very good performance characteristics. Commonly, at suband near-atmospheric pressures, structured packings outperform random packings and trays in capacity and/or separation efficiency (see, e.g., Kurtz et al., 1991; Brunazzi, E....
متن کاملCFD Simulation of Dry and Wet Pressure Drops and Flow Pattern in Catalytic Structured Packings
Type of packings and characteristics of their geometry can affect the flow behavior in the reactive distillation columns. KATAPAK SP is one the newest modular catalytic structured packings (MCSP) that has been used in the reactive distillation columns, recently. However, there is not any study on the hydrodynamics of this packing by using computational fluid dynamics. In the present work, a 3D ...
متن کاملHydrodynamics of Sieve Tray Distillation Column Using CFD Simulation
Sieve trays are widely used in the gas- liquid contactors such as distillation and absorption towers. In this article, a three-dimensional, two phase CFD model using Euler-Euler framework was developed to simulate a distillation tower with two sieve trays. Hydrodynamic simulation of air and water system in different rates of gas phase was carried out and velocity distribution parameters, clear ...
