Time Narration
00:01 Welcome to this tutorial on simulating an Absorption Column using CAPE-OPEN Unit Operation in DWSIM.
00:09 In this tutorial, we will learn to: simulate an Absorption Column,
00:16 use ChemSep column as CAPE-OPEN Unit Operation,
00:20 specify Thermodynamics in ChemSep column,
00:24 specify Pressure profiles & Method in ChemSep column.
00:29 To record this tutorial, I am using: DWSIM 5.2 (Classic UI) and Windows 10.
00:39 The process demonstrated in this tutorial is identical in other OS also such as-

Linux,

Mac OS X or

FOSSEE OS on ARM.

00:51 To practice this tutorial, you should know:
00:56 to add components to a flowsheet,
01:00 select thermodynamic packages,
01:03 add material streams and specify their properties.
01:08 The prerequisite tutorials are mentioned on our website.
01:13 You can access these tutorials and all the associated files from this site.
01:19 We will develop a flowsheet to determine Outlet stream properties after absorption.
01:26 Here we give compounds, inlet stream conditions and property package.
