| | 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
