Art,
Thank you for taking the time to share your experience. To clairfy, the NPSHr value I quoted is from the pump curve published by the pump manufacurer. It dos surprise me that the mysterious effect from the residual dissolved gases which increases the NPSH actually required was not...
Art,
Thank you for your response. I apologize for not stating the problem clear enough. I involved in a number of plant designs although this is my first time involved in an amine unit design team.
Starting from the amine stripper, the proposed layout of the new unit is:
Amine ->...
In most column designs, we put the bottom product pump directly downstream of the column. The column height is adjusted (during design stage) to provide sufficient NPSH for the pump. The only exception that I know of is in the regenerator section of a amine plant. The "accepted practice" is to...
