Able limit of absorber column. Hello everyone I am currently researching more on the design of a amine stripping column but have met some roadblocks. Amine absorber column design
Amine Absorber Column Design, Material balance for the top part of the column is YA t L V A t X A A LX Y V 52-6 In this equation XA and YA are the mole ratios of A in the liquid and vapor phase respectively at any location in the column including at the two terminals. 2 will be absorbed by the amine solution. If you are designing a new distillation column it is advisable to size for about 60 flooding. While simulating in Promax you can specify maximum limit up to 85.
